AWS Code Compliance & Standards 3 — Questions and Answers
Question 1: Which AWS code specifically addresses welding of aluminum structures?
- AWS D1.2 (Correct answer)
- AWS D1.1
- AWS D1.3
- AWS D1.6
Correct answer: AWS D1.2
AWS D1.2 is the Structural Welding Code for Aluminum and governs aluminum structural welding.
Question 2: What is the purpose of a Procedure Qualification Record (PQR)?
- To document the actual welding variables used and test results during WPS qualification (Correct answer)
- To list the names of qualified welders
- To specify the inspection methods required
- To record the material purchase order information
Correct answer: To document the actual welding variables used and test results during WPS qualification
A PQR documents the actual conditions used during welding of test specimens and the results of required tests.
Question 3: Which ASME code section governs welding of pressure vessels?
- ASME Section IX (Correct answer)
- ASME Section I
- ASME Section V
- ASME Section VIII
Correct answer: ASME Section IX
ASME Section IX covers Welding, Brazing, and Fusing Qualifications and applies to pressure vessel and piping welding.
Question 4: Under AWS D1.1, what is the maximum undercut allowed for statically loaded structures in steel 1 inch or less thick?
- 1/32 inch (0.8 mm) (Correct answer)
- 1/8 inch (3.2 mm)
- 1/16 inch (1.6 mm)
- 3/32 inch (2.4 mm)
Correct answer: 1/32 inch (0.8 mm)
AWS D1.1 limits undercut to 1/32 inch for statically loaded structural members 1 inch or less in thickness.
Question 5: Per AWS standards, what does CJP stand for in weld joint design?
- Complete Joint Penetration (Correct answer)
- Certified Joint Procedure
- Carbon Joint Position
- Continuous Joint Profile
Correct answer: Complete Joint Penetration
CJP stands for Complete Joint Penetration, meaning the weld extends through the full thickness of the joint.
Question 6: What is the role of the Welding Inspector (CWI) in code compliance?
- To verify that welding is performed in accordance with the applicable code and WPS (Correct answer)
- To write the Welding Procedure Specification
- To perform all nondestructive testing independently
- To certify the base metal for use in the project
Correct answer: To verify that welding is performed in accordance with the applicable code and WPS
The CWI's role is to inspect and verify that all welding conforms to the applicable code requirements and the approved WPS.
Question 7: Which destructive test evaluates the ductility and soundness of a weld by bending a specimen?
- Guided bend test (Correct answer)
- Nick-break test
- Macro-etch test
- Tensile test
Correct answer: Guided bend test
The guided bend test bends a weld specimen around a die to evaluate ductility and reveal surface or subsurface discontinuities.
