AWS Welding Coordination & QA Endorsement flashcards
AWS Welding Coordination & QA Endorsement · Build recall with a focused review session.
31 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Quality assurance definition
- The planned and systematic activities implemented within a quality system to provide confidence that welding will meet specified requirements, focused on prevention rather than detection.
- Quality control definition
- The operational techniques and activities used to verify that welding work meets acceptance criteria, such as inspection, testing, and measurement of the completed or in-process joint.
- Inspection and test plan
- A project document listing each inspection and test activity with its reference criterion, responsible party, and hold, witness, or review status, used to control verification sequence.
- Hold point
- A stage in the inspection plan where work cannot proceed until the designated party has performed the inspection and recorded acceptance, providing a mandatory pause in production.
- Witness point
- A stage where the designated party is notified and may observe the inspection, but production may continue if the party does not attend as scheduled.
- Essential variable
- A welding parameter whose change beyond the qualified range requires requalification of the procedure, because it can affect the mechanical properties or integrity of the joint.
- Nonconformance report
- A record describing a departure from specified requirements, including the location, the violated criterion, the disposition decision, and the verification of the corrective action.
- Concession disposition
- A documented, authorized acceptance of a nonconforming item without rework or repair, usually requiring customer or design authority approval and a defined service limitation.
- Traceability of consumables
- The ability to link filler metal used in a joint to its batch, certificate, and storage history, so that defects can be investigated and affected welds identified.
- Calibration interval
- The defined period during which a measuring or testing instrument is considered accurate; results obtained outside this period are not valid for acceptance decisions.
- Procedure qualification record
- A documented record of the welding variables used to produce a test weld and the destructive test results demonstrating that the procedure produces acceptable properties.
- Welder qualification test
- A test demonstrating that an individual welder can produce welds meeting acceptance criteria for a specific process, position, and joint configuration within a validity period.
- Visual inspection limits
- Acceptance criteria for surface features such as undercut, porosity, spatter, and profile, applied before any volumetric testing and recorded against the applicable code clause.
- Radiographic testing
- A volumetric examination using penetrating radiation to reveal internal discontinuities; acceptance depends on discontinuity type, size, and distribution against a reference standard.
- Ultrasonic testing
- A volumetric examination using high-frequency sound to detect and size internal planar discontinuities, requiring qualified operators and a written technique for the joint geometry.
- Welding coordination definition
- The organizational function that plans, executes, and verifies welding-related activities so that production, inspection, and documentation conform to specified requirements.
- Coordinator competence basis
- Competence is judged by a combination of technical knowledge of welding processes and standards, practical welding experience, and demonstrated ability to apply that knowledge.
- Contract review
- Examination of the enquiry and order to confirm that welding requirements, standards, delivery, and inspection needs can be met before accepting the work.
- Design feasibility review
- Assessment of whether a specified joint design, material combination, and access arrangement can be welded to the required quality with available processes and equipment.
- Subcontractor verification
- Confirmation that subcontracted welding is performed under equivalent coordination, qualification, and inspection controls, with the coordinating party retaining responsibility.
- Consumable storage control
- Filler metals are kept in conditions matching the manufacturer's requirements, with issue and return records, and hydrogen-sensitive electrodes re-dried per procedure before use.
- Filler metal issue record
- A log linking each batch of filler to the welder and joint, enabling identification of affected work if a consumable-related defect is later found.
- Equipment suitability check
- Verification that welding power sources and ancillary equipment match the process, current range, duty cycle, and position needs of the planned work.
- Preheat control
- Establishing and verifying minimum preheat and maximum interpass temperature before and during welding, measured at defined distances from the joint using calibrated devices.
- Welding sequence planning
- Determining the order and direction of passes and joints to control distortion and residual stress, documented before production begins.
- Fit-up verification
- Checking root gap, edge preparation, alignment, and dimensional tolerances before welding, since fit-up deviations can cause defects that later inspection cannot correct.
- Post-weld heat treatment
- A controlled heating and cooling cycle applied after welding to relieve residual stress or temper the microstructure, requiring documented parameters and temperature records.
- Personnel qualification matrix
- A register showing which welders and operators are qualified for which process, position, and joint type, with validity dates and renewal requirements.
- Welding procedure specification
- A document specifying the qualified welding variables, including process, materials, joint design, and parameters, that production must follow for a given application.
- Production planning document
- A record of the planned welding sequence, personnel, equipment, consumables, and inspection points that is issued before work starts and updated as work progresses.
- Final documentation review
- Verification before handover that qualification records, inspection reports, nonconformance closures, and traceability records are complete and consistent with the specification.
