Question 1Welding Quality Assurance

In a welding quality assurance system, what is the primary purpose of a Welding Procedure Specification (WPS)?

  1. To record the results of visual inspection after welding
  2. To provide the qualified set of welding variables used to produce a sound joint Correct answer.
  3. To document the welder's personal certification history
  4. To list the purchase cost of consumables

Explanation

A WPS is a written, qualified document that specifies the essential, non-essential and supplementary essential variables for producing a weld that meets specified requirements. It guides the welder and inspector so that production welds match the conditions proven by procedure qualification testing.

Question 2Welding Quality Assurance

Which document records the actual variables used during welding of a specific production joint?

  1. The welding record or weld map Correct answer.
  2. The welder performance certificate
  3. The material test certificate
  4. The Welding Procedure Qualification Record

Explanation

The welding record (sometimes called a weld map or production record) captures the actual parameters, welder identity and joint identification applied to a specific production weld. It provides traceability linking the WPS to what was really done.

Question 3Welding Quality Assurance

A welder qualified under one WPS is assigned to weld a joint using a different process not covered by that qualification. What is the correct QA action?

  1. Allow welding if a supervisor observes the first joint
  2. Allow welding if the welder has more than five years of experience
  3. Require requalification for the new process before production welding Correct answer.
  4. Allow welding provided the joint is later radiographed

Explanation

Welder qualification is specific to the process, position and essential variables covered by the test. Changing to an unqualified process requires new qualification testing before the welder may produce production welds under that process.

Question 4Welding Quality Assurance

What does a procedure qualification record primarily demonstrate?

  1. That the welding equipment has been calibrated within the last year
  2. That the welder can work at the required production rate
  3. That the consumables were stored correctly
  4. That a proposed welding procedure can produce a joint meeting the required mechanical properties Correct answer.

Explanation

Procedure qualification involves welding a test coupon to the proposed specification and subjecting it to mechanical and nondestructive tests. Passing results demonstrate that the procedure, as written, can deliver the required joint properties.

Question 5Welding Quality Assurance

Which of the following best describes the role of a welding coordinator in a quality assurance system?

  1. Designing the structural load calculations for the product
  2. Performing all production welds personally
  3. Managing and verifying welding activities, personnel and documentation to meet quality requirements Correct answer.
  4. Setting the commercial price of welded fabrications

Explanation

The welding coordinator oversees that welding is planned, executed and documented in accordance with the applicable quality requirements. This includes verifying personnel qualification, procedure availability and inspection arrangements.

Question 6Welding Quality Assurance

Why must welding consumables be stored and handled according to the manufacturer's recommendations?

  1. To allow the use of lower welding current
  2. To reduce the insurance premium of the workshop
  3. To shorten the arc time during welding
  4. To ensure the consumable's chemical composition and moisture content remain within specification Correct answer.

Explanation

Many consumables, particularly basic-coated electrodes and flux, absorb moisture if exposed to humid air, which can cause hydrogen-induced cracking and porosity. Controlled storage and re-drying preserve the composition and low-hydrogen condition specified for the procedure.

Question 7Welding Quality Assurance

What is the main purpose of a visual inspection performed before welding begins?

  1. To measure the final weld profile
  2. To verify joint preparation, fit-up and cleanliness meet the specification Correct answer.
  3. To confirm the tensile strength of the completed joint
  4. To determine the welder's hourly output

Explanation

Pre-weld visual inspection checks that the joint geometry, gap, bevel, cleanliness and fit-up conform to the drawing and WPS before any arc is struck. Catching deviations at this stage prevents defects that would be costly to repair later.

Question 8Welding Quality Assurance

Which record typically provides traceability between the base material used and the finished welded product?

  1. The welder's training attendance sheet
  2. The workshop layout drawing
  3. The equipment maintenance log
  4. The material test certificate linked to the heat number Correct answer.

Explanation

A material test certificate identifies the heat number and the chemical and mechanical properties of the supplied material. Linking that heat number to the product through production records provides material traceability.

Question 9Welding Quality Assurance

During production, a welder proposes increasing the current beyond the range stated in the WPS to improve penetration. What should the coordinator do?

  1. Refuse any change and stop all welding permanently
  2. Approve the change immediately because penetration improves
  3. Authorize the change only after the WPS is revised and requalified as required Correct answer.
  4. Allow the change for one shift and record it afterwards

Explanation

Welding current is typically an essential variable, so a change outside the qualified range may invalidate the procedure. The correct route is to revise the WPS and, where the variable is essential, requalify before production use.

Question 10Welding Quality Assurance

A welder qualified in the flat position is asked to weld in the vertical-up position on the same process and joint type. What does proper QA practice require?

  1. No action, because position is not a qualification variable
  2. Only a change of welding current
  3. Approval by the customer's purchasing department
  4. Verification that the existing qualification covers the vertical position or requalification Correct answer.

Explanation

Welding position is normally an essential variable for welder qualification, and a test in one position does not automatically cover all others. The coordinator must confirm the qualification range covers the required position or arrange a new test.

Question 11Welding Quality Assurance

Which action best ensures that measuring equipment used for weld inspection remains reliable?

  1. Scheduling periodic calibration against traceable standards and recording the results Correct answer.
  2. Storing the instrument in the welder's toolbox
  3. Letting each inspector judge accuracy by feel
  4. Recalibrating the instrument only when a defect is found

Explanation

Inspection gauges and instruments must be calibrated at defined intervals against standards traceable to a national or international reference. Records of calibration demonstrate that measurements taken during inspection are valid.

Question 12Welding Quality Assurance

A surface-breaking crack is detected in a finished fillet weld. What is the most appropriate immediate QA response?

  1. Reduce the inspection frequency for that welder
  2. Paint over the area to prevent moisture ingress
  3. Increase the welding current on the next joint only
  4. Record the defect, mark the location and initiate the approved repair procedure Correct answer.

Explanation

A crack is a rejectable defect that must be documented and repaired according to an approved procedure, often including excavation to sound metal and re-inspection. Recording the location preserves traceability and supports root-cause analysis.

Question 13Welding Quality Assurance

What is the purpose of a hold point in a welding quality plan?

  1. To require that work stops and specified inspection or approval occurs before proceeding Correct answer.
  2. To reduce the number of welders on the project
  3. To allow work to continue while inspection is arranged later
  4. To record the cost of welding consumables

Explanation

A hold point is a stage in the quality plan where work must not proceed until the designated inspection or approval has been completed and documented. It prevents concealment of work that requires verification.

Question 14Welding Quality Assurance

A procedure qualification test coupon fails its bend test. What is the correct interpretation for the QA system?

  1. The procedure is qualified because other tests may have passed
  2. The bend test result should be deleted from the record
  3. The procedure is not qualified and must be investigated and requalified Correct answer.
  4. The failure can be ignored if the welder is experienced

Explanation

All required tests in the qualification standard must be satisfied for the procedure to be qualified. A failed bend test indicates the procedure is not yet proven, so the cause must be investigated and the procedure requalified.

Question 15Welding Quality Assurance

How should welding consumables that have exceeded their specified holding time after opening be treated?

  1. Re-dried or otherwise conditioned per the manufacturer's instructions before use, or rejected Correct answer.
  2. Mixed with new consumables to extend their life
  3. Used immediately without any further action
  4. Used only for non-structural tack welds

Explanation

Consumables exposed beyond the permitted holding time may have absorbed moisture and must be conditioned according to the manufacturer's recommendations, such as re-drying, or else rejected. Using them unconditionally risks hydrogen cracking and porosity.

Question 16Welding Quality Assurance

An inspector finds that a weld's reinforcement height exceeds the acceptance limit. Which classification and action is appropriate?

  1. A geometric imperfection to be assessed against the acceptance criteria and corrected if rejectable Correct answer.
  2. A critical defect requiring immediate scrapping of the component
  3. A cosmetic issue that requires no record
  4. A material nonconformity chargeable to the steel mill

Explanation

Excessive reinforcement is a geometric imperfection whose acceptability depends on the applicable acceptance criteria, such as those for weld profile. If it exceeds the limits it is treated as a nonconformity and corrected, for example by grinding.

Question 17Welding Quality Assurance

Which practice best supports root-cause analysis when repeated porosity is found in production welds?

  1. Recording parameters, consumable batch, gas flow and environmental conditions for affected welds Correct answer.
  2. Blaming the welder and taking no further action
  3. Increasing the inspection sampling rate only
  4. Repairing each weld without collecting any data

Explanation

Systematic data collection on parameters, consumables, shielding gas and site conditions allows correlations to be identified and the true cause isolated. Without such records, repairs treat symptoms rather than causes.

Question 18Welding Quality Assurance

What does the term 'essential variable' mean in the context of a welding procedure?

  1. A variable that can be changed freely by the welder
  2. A variable related only to the cost of production
  3. A variable that affects the mechanical properties or soundness of the weld and requires requalification if changed Correct answer.
  4. A variable that only affects the appearance of the weld

Explanation

Essential variables are those parameters, such as process, filler classification, current range or preheat, whose change beyond the qualified range can affect the joint properties. Changing them requires the procedure to be requalified.

Question 19Welding Quality Assurance

A fabrication uses a steel grade with a higher carbon equivalent than originally specified. What is the most appropriate QA consideration?

  1. Assess the need for increased preheat and revised procedure qualification before welding Correct answer.
  2. Weld without preheat and inspect afterwards only
  3. No change is needed because welding parameters are fixed
  4. Reduce preheat to save time

Explanation

A higher carbon equivalent increases hardenability and the risk of hydrogen-assisted cold cracking, so preheat and interpass controls may need to be increased. This generally requires a revised and requalified procedure before production.

Question 20Welding Quality Assurance

Which of the following is the most reliable evidence that a welder's qualification remains valid at the time of production welding?

  1. A current qualification certificate confirming scope, validity and continuity Correct answer.
  2. A photograph of the welder's previous work
  3. The welder's membership of a trade association
  4. A verbal assurance from the welder

Explanation

Valid qualification is demonstrated by a certificate that identifies the process, position and range covered and confirms that validity has been maintained, for example through continuity of employment. This documentary evidence is what the quality system relies upon.

Question 21Welding Quality Assurance

When establishing the inspection and testing plan for a pressure-retaining weld, which sequence is technically sound?

  1. Procedure qualification, then production welding with in-process inspection, then final NDT and pressure test Correct answer.
  2. Final NDT, then welder qualification, then production welding
  3. Final hydrostatic test, then root inspection, then procedure qualification
  4. Production welding, then procedure qualification, then visual inspection

Explanation

Qualification of the procedure and personnel must precede production, with in-process inspection controlling the work as it proceeds. Final nondestructive testing and the pressure test then verify the completed joint in the correct order.

Question 22Welding Quality Assurance

A repair weld is made on a joint that was already subjected to a qualification-critical heat treatment. What is the key QA requirement?

  1. The repair should be left uninspected to save cost
  2. The repair procedure and any post-weld heat treatment must be qualified and documented, and the joint re-inspected Correct answer.
  3. The repair can be covered by the original WPS without review
  4. No further action is required because the repair is small

Explanation

Repairs introduce new thermal cycles and may require a qualified repair procedure and repeat of post-weld heat treatment, followed by re-inspection. Documenting the repair preserves traceability and confirms the joint still meets requirements.

Question 23Welding Quality Assurance

Two procedures produce acceptable tensile results, but one shows consistently higher scatter in Charitable impact values near the specified minimum. How should the coordinator interpret this?

  1. The higher-scatter procedure indicates less process control and warrants investigation before adoption Correct answer.
  2. Scatter is irrelevant if the average passes
  3. Both are equally robust because tensile tests passed
  4. The procedure with scatter should be adopted because it is cheaper

Explanation

High scatter in impact results near the acceptance minimum signals variability in essential variables such as heat input or consumable condition. Investigating and tightening process control reduces the risk of marginal production joints.

Question 24Welding Quality Assurance

An audit finds that production welds were made with a WPS whose supporting qualification record cannot be located. What is the most defensible QA conclusion?

  1. The welds are acceptable if the welder is highly experienced
  2. The welds lack documented procedure qualification and must be treated as nonconforming pending investigation Correct answer.
  3. The missing record can be recreated from memory by the supervisor
  4. The welds are automatically acceptable because they passed visual inspection

Explanation

Without a locatable qualification record, there is no objective evidence that the procedure was ever qualified, so conformity cannot be demonstrated. The welds should be treated as nonconforming until the evidence is found or the situation is otherwise resolved.

Question 25Welding Quality Assurance

A quality plan specifies 10 percent radiographic testing of butt welds, but the client requests 100 percent on a critical vessel. How should the coordinator respond?

  1. Refuse because the plan cannot be changed once issued
  2. Apply 100 percent testing to all future projects automatically
  3. Revise the inspection plan to reflect the increased testing and document the change through the agreed change control Correct answer.
  4. Perform the extra testing without recording it

Explanation

Inspection plans are controlled documents that may be revised when requirements change, provided the revision follows the agreed change control process and is recorded. The increased testing is then implemented and its results documented.

Question 26Welding Quality Assurance

Which document defines the welding variables that a welder must follow for a specific production joint?

  1. The welding procedure specification Correct answer.
  2. The nondestructive testing report
  3. The purchase order for base metal
  4. The welder performance certificate

Explanation

The welding procedure specification is the controlled document that lists the qualified ranges of current, voltage, travel speed, consumable, and joint preparation for a given joint. Production welding must follow it, and any departure requires requalification or documented approval. Other documents support or record work but do not prescribe the welding variables.

Question 27Welding Quality Assurance

What is the primary purpose of a welding procedure qualification record?

  1. To record the daily preheat temperature log
  2. To list the welders employed on a project
  3. To certify the calibration status of welding machines
  4. To document the test results that prove a procedure produces sound welds Correct answer.

Explanation

A procedure qualification record captures the essential variables used to weld a test coupon and the mechanical test results obtained from it. It is the objective evidence that the procedure can deliver the required properties. It does not track personnel, daily production conditions, or equipment calibration.

Question 28Welding Quality Assurance

A quality control inspector identifies a weld that meets all acceptance criteria but whose surface finish is rougher than the drawing note requires. How should this be classified?

  1. A welder qualification failure
  2. An acceptable condition needing no action
  3. A nonconformity against a specified requirement Correct answer.
  4. A critical defect requiring immediate rejection

Explanation

Any departure from a specified requirement, including finish or dimensional notes on the drawing, is a nonconformity even when structural acceptance criteria are met. It must be recorded and dispositioned through the quality system. It is not automatically a critical defect, and it cannot simply be ignored.

Question 29Welding Quality Assurance

Which activity verifies that a welding machine's output meter reads accurately before production use?

  1. Calibration against a reference instrument Correct answer.
  2. Review of the consumable certificate
  3. Visual inspection of the cable insulation
  4. A destructive bend test of a coupon

Explanation

Calibration compares the instrument's indication with a traceable reference standard and documents the result. This is the accepted method for confirming measurement reliability. Cable inspection, mechanical testing, and consumable certification address different concerns.

Question 30Welding Quality Assurance

What does a welder qualification test primarily demonstrate?

  1. That the welding procedure has adequate toughness
  2. That the welder can produce welds meeting the required standard for a defined scope Correct answer.
  3. That the base metal meets its specification
  4. That the shop's quality system is certified

Explanation

Welder qualification tests the individual's ability to deposit sound welds within a defined range of process, position, and joint configuration. Procedure qualification, material certification, and system certification are separate demonstrations. Confusing them is a common audit finding.

Question 31Welding Quality Assurance

Which of the following is a destructive test commonly used to evaluate the soundness of a procedure qualification butt weld?

  1. Magnetic particle examination
  2. Transverse tensile test Correct answer.
  3. Ultrasonic examination
  4. Dye penetrant examination

Explanation

Mechanical tests such as transverse tensile, bend, and impact tests are destructive and are used to qualify procedures. Penetrant, ultrasonic, and magnetic particle methods are nondestructive and do not remove material for property evaluation.

Question 32Welding Quality Assurance

What is the main purpose of maintaining traceability of filler metal batches used on a project?

  1. To allow investigation and recall if a consumable-related problem arises Correct answer.
  2. To replace the need for procedure qualification
  3. To reduce the purchase cost of consumables
  4. To satisfy the welder's personal recordkeeping

Explanation

Batch traceability links delivered welds to the specific consumable lots used, enabling targeted investigation and containment if a problem is later found. It supports quality assurance but does not affect cost, replace qualification, or serve individual recordkeeping.

Question 33Welding Quality Assurance

Which term describes the documented examination of a weld by a qualified person using senses and simple tools without damaging the weld?

  1. Radiographic testing
  2. Hardness testing
  3. Macro etching
  4. Visual inspection Correct answer.

Explanation

Visual inspection examines the weld surface and profile using eyesight and simple gauges, and it does not damage the component. Radiography, hardness testing, and macro etching either use radiation or remove material for evaluation.

Question 34Welding Quality Assurance

A welder qualified for a process on 10 mm plate is assigned to weld 25 mm plate under the same procedure. What must the QA function confirm before production?

  1. That the thickness range of the welder's qualification covers 25 mm Correct answer.
  2. That the joint will be radiographed in full
  3. That the welder has at least five years of experience
  4. That the base metal certificate is less than one year old

Explanation

Welder qualifications are valid only within the thickness range recorded on the qualification, and exceeding that range requires requalification. Experience, certificate age, and inspection extent do not substitute for qualification coverage. Confirming the range is the essential QA check.

Question 35Welding Quality Assurance

A procedure qualification record lists a preheat of 100 °C, but production drawings specify 150 °C. How should the QA engineer respond?

  1. Permit production only if the welder agrees
  2. Require evaluation of the change against the qualified essential variables before release Correct answer.
  3. Reject the drawings and demand they match the record exactly
  4. Allow production because higher preheat is always beneficial

Explanation

Preheat is generally an essential variable, and a change beyond the qualified range must be assessed, and if necessary requalified, before release. Higher preheat is not automatically acceptable because it can alter mechanical properties. Neither the welder's opinion nor a simple rejection resolves the technical question.

Question 36Welding Quality Assurance

Which action best demonstrates that a corrective action for repeated lack-of-fusion defects has been effective?

  1. Closing the corrective action report after the welder is retrained
  2. Increasing the amount of final inspection on finished goods
  3. Filing the defect reports in the project quality record
  4. Monitoring subsequent production welds and confirming the defect rate falls Correct answer.

Explanation

Effectiveness is verified by data showing the problem is reduced or eliminated after the action is implemented. Retraining, added inspection, and filing records are activities, not evidence of outcome. Monitoring subsequent production provides that evidence.

Question 37Welding Quality Assurance

An inspector must confirm that a fillet weld throat thickness meets the drawing. Which approach is technically appropriate?

  1. Measure the leg lengths with a fillet weld gauge and calculate the throat Correct answer.
  2. Rely on the welder's stated settings for the pass
  3. Compare the weld with an adjacent joint made by the same welder
  4. Estimate the size by eye and record the nominal value

Explanation

Fillet weld size is verified by measuring leg lengths with a suitable gauge and deriving the throat thickness from the geometry. Eyeball estimates, machine settings, and comparison with other joints are not measurements. Objective measurement is required for acceptance decisions.

Question 38Welding Quality Assurance

A fabricator wants to substitute a consumable of the same classification from a different manufacturer without notifying the client. What is the QA position?

  1. The change is acceptable only for non-pressure parts
  2. The change must be assessed against the specification and approved before use Correct answer.
  3. Substitution is acceptable because the classification is identical
  4. Substitution is acceptable if the welder prefers the new product

Explanation

Consumable brand changes can affect arc behaviour, chemistry, and hydrogen content, so they must be assessed against project requirements and formally approved. Identical classification does not guarantee identical performance. Welder preference and part category do not authorize unapproved changes.

Question 39Welding Quality Assurance

Which element of a welding quality plan defines the point at which work may not proceed without documented client or inspector approval?

  1. A hold point Correct answer.
  2. A review point
  3. A surveillance point
  4. A witness point

Explanation

A hold point stops work until the designated party has inspected and recorded approval. A witness point requires notification but does not stop work if the party does not attend. Surveillance and review are broader activities without the stop-work effect.

Question 40Welding Quality Assurance

An audit finds that welders are using a procedure whose qualification supports a lower heat input than that being applied. What is the most appropriate immediate action?

  1. Stop the affected work and quarantine the welds pending evaluation Correct answer.
  2. Continue production and note the issue in the final report
  3. Recalibrate the welding machines and resume
  4. Retrain the welders at the next scheduled session

Explanation

Welds made outside the qualified heat input range have no demonstrated property basis, so work must stop and the affected welds must be contained and evaluated. Documentation alone does not protect the product. Calibration and training do not address the nonconforming welds already produced.

Question 41Welding Quality Assurance

Which practice best ensures that welding consumables remain suitable for use after a package is opened?

  1. Using opened packages within the same shift regardless of condition
  2. Returning unused consumables to a controlled holding oven or sealed store Correct answer.
  3. Marking opened packages with the welder's initials
  4. Storing opened packages in the open workshop

Explanation

Many consumables absorb moisture once opened, so they must be returned to controlled storage, such as a holding oven or sealed container, per the manufacturer's instructions. Open workshop storage, unrestricted same-shift use, and initialing do not control moisture pickup.

Question 42Welding Quality Assurance

Two identical production joints show different weld bead profiles although the same procedure was followed. Which factor is most likely to explain the difference?

  1. The calibration sticker on the machine
  2. The base metal certificate number
  3. The project quality plan revision
  4. The welder's travel technique and manipulation Correct answer.

Explanation

Bead profile is strongly influenced by the individual welder's travel angle, speed, and manipulation even when current and voltage follow the procedure. Certificate numbers, calibration labels, and plan revisions do not directly alter bead shape. This is why welder technique is controlled through qualification.

Question 43Welding Quality Assurance

A hardness survey shows values above the acceptance limit in the heat-affected zone of a pressure weld. What is the most appropriate QA response?

  1. Reduce the design pressure without further assessment
  2. Investigate the thermal history and agree a disposition with the responsible engineer Correct answer.
  3. Accept the result because hardness does not affect pressure integrity
  4. Repaint the area and re-test at a later date

Explanation

Excessive hardness in the heat-affected zone indicates a thermal history that may reduce toughness or cracking resistance, so the cause and the affected extent must be evaluated and dispositioned. Ignoring the result or repainting does not address the condition. Changing design pressure is a design decision that requires proper assessment.

Question 44Welding Quality Assurance

Which record set best supports a claim that a completed weld was made under controlled conditions?

  1. The approved procedure, the welder's valid qualification, and the production inspection records Correct answer.
  2. The client's email correspondence and the site diary
  3. The welder's resume and the machine purchase invoice
  4. The consumable advertisement and the safety briefing sheet

Explanation

Control of welding is evidenced by an approved procedure, a qualification valid for the scope, and production records showing the specified parameters and inspection results. Resumes, invoices, correspondence, and safety sheets are not technical evidence of welding control.

Question 45Welding Quality Assurance

A weld repair is proposed on a joint that has already received its final post-weld heat treatment. What is the key QA consideration?

  1. Whether the repair and subsequent heat treatment will restore the required properties Correct answer.
  2. Whether the client's representative is on site
  3. Whether the welder has previously repaired similar joints
  4. Whether the repair can be completed within the same shift

Explanation

Repair welding introduces new thermal cycles that can alter microstructure and residual stress, so the need for and effect of further heat treatment must be assessed against the qualified condition. Shift timing, prior experience, and attendance are administrative matters. The technical outcome governs acceptance.

Question 46Welding Quality Assurance

An inspector notices that the same welder produced acceptable root beads on one joint but excessive penetration on a similar joint the next day. Which investigation path is most appropriate?

  1. Increase the inspection frequency for the rest of the project
  2. Requalify all welders on site
  3. Assume the base metal changed and reject the material
  4. Review the welding parameters, fit-up, and root gap records for both joints Correct answer.

Explanation

A change in outcome between similar joints points to variation in parameters, fit-up, or root gap, so those records should be compared first. Blaming the material or requalifying everyone is disproportionate without evidence. Increasing inspection detects but does not explain the cause.

Question 47Welding Quality Assurance

A procedure qualification yields acceptable tensile results but impact values close to the minimum, with high scatter between specimens. How should the QA engineer interpret this?

  1. The procedure is fully acceptable because all values pass
  2. The margin is narrow and the scatter warrants review before production release Correct answer.
  3. The impact test should be ignored because tensile passed
  4. The procedure should be rejected without further consideration

Explanation

Results that pass with little margin and high scatter indicate limited robustness and should prompt review of variables such as heat input and consumable condition before release. Passing values alone do not guarantee consistent production. Ignoring the data or outright rejection without review are both unjustified.

Question 48Welding Quality Assurance

A client requests 100 percent radiographic testing on a critical butt weld, while the approved plan requires 10 percent. What is the correct QA action?

  1. Apply the extra testing only if the welder agrees
  2. Refuse the request because the plan is already approved
  3. Process a documented plan change and implement the increased testing Correct answer.
  4. Perform the extra testing without recording the change

Explanation

Changes to inspection extent must be handled through the documented change control process so that the plan, records, and responsibilities remain consistent. Refusing a stricter client requirement is unhelpful, and performing extra work without recording it creates a documentation gap. The welder's agreement is irrelevant.

Question 49Welding Quality Assurance

Which situation most clearly indicates that a welding quality management system is not functioning effectively?

  1. Welders attend refresher training annually
  2. Inspection records are completed after each shift
  3. The same systematic defect recurs because corrective actions are not verified Correct answer.
  4. Nonconformities are raised and closed with verified actions

Explanation

An effective system prevents recurrence through verified corrective action, so repeated systematic defects signal a breakdown in that process. Timely records, properly closed nonconformities, and refresher training are positive indicators. The distinguishing feature is the absence of effective correction.

Question 50Welding Quality Assurance

A subcontractor supplies welded assemblies with mill certificates for the base metal but no records of the welding parameters used. How should the QA function treat this delivery?

  1. Accept the assemblies if visual inspection shows no defects
  2. Return the assemblies without any communication
  3. Hold the assemblies pending receipt of acceptable welding records or re-verification Correct answer.
  4. Accept the assemblies because material certificates are present

Explanation

Material certificates alone do not demonstrate that welding was performed under controlled conditions, so the assemblies should be held until adequate welding records are provided or the required verification is completed. Visual inspection cannot confirm that qualified parameters were used. Unilateral return without communication is poor practice.
