Exam QUESTIONS AND CORRECT ANSWERS WITH
RATIONALES
AWS Senior Certified Welding Inspector (SCWI) Exam Practice Questions
10-Point Exam Coverage — Mostly Tested Areas
1. Welder Performance Qualification — welder qualification requirements, test positions,
essential variables, continuity, qualification ranges, test records, performance testing, and
interpretation of results.
2. Welding Procedure Specifications (WPS) — WPS preparation, essential variables, supporting
PQRs, qualified ranges, welding processes, materials, thickness, preheat, interpass temperature,
filler metals, shielding gas, and electrical parameters.
3. Procedure Qualification Records (PQR) — recording actual test variables, mechanical testing,
test results, acceptance requirements, traceability, and determining whether a WPS is properly
supported.
4. Welding Inspection and Quality Assurance — inspection planning, quality systems, hold points,
acceptance criteria, documentation, audits, corrective action, nonconformance control, and
quality records.
5. Nondestructive Examination Coordination — VT, PT, MT, RT, UT, examination selection,
limitations, procedures, personnel qualification, indications, evaluation, and reporting.
6. Welding Metallurgy and Materials — weldability, heat-affected zones, carbon equivalent,
hardness, cracking, heat treatment, material identification, distortion, residual stress, and
metallurgical effects.
7. Welding Processes and Discontinuities — SMAW, GMAW, FCAW, GTAW, SAW, process
variables, common defects, causes, prevention, and repair.
8. Inspection Management and Project Coordination — inspector responsibilities, inspection
procedures, supplier audits, subcontractor control, inspection staffing, communication,
scheduling, and coordination with engineering.
9. Codes, Standards, Specifications, and Contract Requirements — correct code selection,
specification interpretation, drawings, welding symbols, acceptance criteria, contract
requirements, revisions, and code compliance. AWS maintains numerous structural welding
standards, including D1.1, D1.2, D1.3, D1.5, and D1.6. (American Welding Society)
10. Professional Responsibility and Senior-Level Leadership — ethics, impartiality, technical
decisions, audit leadership, records, personnel supervision, risk-based inspection, quality
improvement, and resolving conflicting requirements.

A senior inspector reviews a WPS before production welding begins; what should be verified first about
the procedure?
A. The welder's personal preference
B. The supporting qualification and applicable requirements
C. The welding shop's production schedule
D. The inspector's preferred welding process
Answer: B
Rationale: A WPS must be properly supported and applicable to the work before production welding
begins.
2.
During a supplier audit, the inspector finds repeated weld defects that were not reported in quality
records; what should happen next?
A. Ignore the defects if production is complete
B. Delete the affected records
C. Document the finding and begin corrective action
D. Ask the welder to hide future defects
, Page 3 of 143
Answer: C
Rationale: Repeated undocumented defects indicate a quality-system problem requiring documented
corrective action.
3.
A PQR contains the actual welding variables used during qualification testing; why are these actual
values important?
A. They establish what was actually used during the qualification test
B. They show the inspector's favorite settings
C. They replace all production drawings
D. They determine the contractor's final payment
Answer: A
Rationale: The PQR records actual qualification variables and test results used to support the WPS.
4.
A welder passes a qualification test using one welding process but later uses another process; what
should the inspector verify?
, Page 4 of 143
A. Only the weld appearance
B. Whether the qualification covers the new process
C. The welder's years of employment
D. The material delivery date
Answer: B
Rationale: Welder qualification is process-specific and must cover the process being used.
5.
An inspector sees surface cracking immediately after welding and must determine the proper response;
what is most appropriate?
A. Paint over the crack
B. Accept the weld because it is small
C. Document and evaluate the crack using applicable requirements
D. Grind every weld in the project
Answer: C
Rationale: Cracking is significant and must be evaluated against applicable inspection and acceptance
requirements.
