Correct Answer: B
2. Which organization publishes the AWS D1.1 Structural
Welding Code – Steel?
A. ASTM
B. AISC
C. American Welding Society (AWS)
D. OSHA
,Rationale: AWS is responsible for structural welding codes used
in inspection.
Correct Answer: C
3. What does a weld discontinuity refer to?
A. A required weld feature
B. An interruption in the weld structure
C. A welding procedure specification
D. A welding machine setting
Rationale: Discontinuities are imperfections that may or may
not be defects.
Correct Answer: B
4. Which welding process uses a continuously fed electrode
wire and shielding gas?
A. SMAW
B. GMAW
C. SAW
D. FCAW-S
Rationale: Gas Metal Arc Welding (GMAW) uses wire feed and
shielding gas.
Correct Answer: B
,5. What is the main function of a Welding Procedure
Specification (WPS)?
A. To describe inspection methods
B. To define welding parameters and requirements
C. To certify welders
