CAWI study plan

CAWI · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Welding Inspection and Certification Fundamentals & Welding Processes, Procedures, and Qualifications

  • Define the CAWI certification scope, eligibility routes, and renewal or recertification requirements in your own words

  • Map the duties of an inspector versus a welding supervisor, welding engineer, and third-party examiner, listing at least eight distinct responsibilities for the inspector

  • Identify the main reference standards landscape (ISO 9606, ISO 15614, ISO 5817, AWS D1.1, ASME Section IX) and state what each one governs without confusing their scopes

  • Build a personal glossary of 30 inspection and certification terms with a one-line definition for each

Your checkpoint

A one-page certification roadmap plus a 30-term glossary, self-quizzed to 90 percent accuracy

Week 2

Welding Inspection and Certification Fundamentals & Welding Processes, Procedures, and Qualifications

  • Trace the document flow from enquiry through welding procedure specification, procedure qualification record, welder qualification, production, and final acceptance

  • Explain the inspector's role at each hold point and witness point in that flow

  • Distinguish procedure qualification from welder performance qualification using at least four concrete contrasts

  • Draft a checklist an inspector would use before welding starts on a new job

Your checkpoint

A process-flow diagram with inspector hold points annotated, plus a pre-weld checklist of at least 15 items

Week 3

Welding Processes, Procedures, and Qualifications

  • Compare SMAW, GMAW, FCAW, GTAW, and SAW on heat input, deposition rate, typical positions, and common defects

  • Describe how process selection drives procedure qualification variables and essential versus non-essential variables

  • Summarize the essential variables for a procedure qualification test and explain why each one is controlled

  • Explain the range-of-qualification concept for thickness, diameter, position, and process

Your checkpoint

A comparison matrix covering five processes across at least six attributes, with essential variables highlighted

Week 4

Welding Processes, Procedures, and Qualifications & Welding Metallurgy, Materials, and Weldability

  • Walk through a procedure qualification test step by step: preparation, welding, specimen extraction, testing, and acceptance

  • Interpret a welder qualification test record and determine whether the welder's qualification covers a given production joint

  • Relate heat input calculations to procedure limits and demonstrate the arithmetic

  • Predict how a change in preheat, current, or travel speed affects qualification validity

Your checkpoint

Two worked case studies: one procedure qualification and one welder qualification, each with a written accept or reject decision and justification

Week 5

Welding Metallurgy, Materials, and Weldability

  • Describe the iron-carbon equilibrium diagram and the effect of cooling rate on ferrite, pearlite, bainite, and martensite formation

  • Explain the heat-affected zone and how peak temperature and cooling time change its microstructure and toughness

  • Define hardenability, carbon equivalent, and hydrogen-assisted cold cracking, and state the countermeasures for each

  • Classify carbon steels, low-alloy steels, stainless steels, and aluminium alloys by weldability concerns

Your checkpoint

A one-page HAZ diagram with annotated zones and a table of at least 10 material groups with their principal weldability risks

Week 6

Welding Metallurgy, Materials, and Weldability & Weld Examination, Testing, and Code Compliance

  • List the main weld discontinuities and explain which are planar, which are volumetric, and why that distinction changes detection method

  • Match each discontinuity type to the examination method most likely to detect it

  • Explain the metallurgical mechanisms behind solidification cracking, lamellar tearing, and reheat cracking

  • Interpret a carbon equivalent value and recommend preheat and interpass controls for a given steel

Your checkpoint

A defect-to-method matrix covering at least 12 discontinuities with detection rationale for each

Week 7

Weld Examination, Testing, and Code Compliance

  • Compare visual, penetrant, magnetic particle, ultrasonic, and radiographic examination on principle, typical applications, and limitations

  • Explain sensitivity, technique, and acceptance criteria as separate concepts in non-destructive examination

  • Interpret quality levels or acceptance categories for weld imperfections and apply them to sample indications

  • Describe destructive tests used in qualification: tensile, bend, impact, hardness, and macro examination, and what each proves

Your checkpoint

Five practice interpretation scenarios where you assign an acceptance decision to described indications and defend it in writing

Week 8

Welding Inspection and Certification Fundamentals & Welding Processes, Procedures, and Qualifications & Welding Metallurgy, Materials, and Weldability & Weld Examination, Testing, and Code Compliance

  • Review all four domains using a spaced-repetition pass over your glossary, matrices, and case studies

  • Complete at least two timed mixed-domain practice sets and analyse every error by root cause

  • Re-derive the highest-risk calculations from memory: heat input, carbon equivalent, and range of qualification

  • Write a personal weak-area list with a remediation action for each item

Your checkpoint

A full timed mock examination scored and reviewed, with an error log and remediation plan

Milestones

Week 2: Explain the document flow and inspector hold points to a colleague or on paper without notes, and score at least 85 percent on a self-made fundamentals quiz

Week 4: Correctly decide both qualification case studies, including identifying at least one variable that would invalidate the qualification

Week 6: Match at least 10 of 12 discontinuities to their most likely detection method and justify each choice in one sentence

Week 8: Score at least 75 percent on the timed mixed-domain mock examination with no domain below 65 percent
