LATEST AWS D1.1 STRUCTURAL WELDING
CODE CERTIFICATION (STEEL) EXAM OFFERED
BY AMERICAN WELDING SOCIETY (AWS) | Q&A
WITH RATIONALES
1. Which AWS document is the primary code for
welding of structural steel in buildings and bridges?
A) AWS D1.5
B) AWS D1.2
C) ASME Section IX
D) AWS D1.1
Correct answer: D
Rationale: AWS D1.1 is the primary code for welding
of structural steel; D1.2 covers aluminum and D1.5
covers bridges.〖17†L18-L20〗
2. AWS D1.1 applies primarily to which base
material(s)?
A) Aluminum
B) Stainless steel
C) Carbon and low‑alloy steel
,D) Cast iron
Correct answer: C
Rationale: AWS D1.1 applies to carbon and low‑alloy
steels commonly used in structures; non‑ferrous
alloys are outside its scope.〖15†L20-L24〗
3. Which of the following is explicitly excluded from
the scope of AWS D1.1?
A) Carbon steel plate 1/8″ or greater
B) Low‑alloy steel plate 1/8″ or greater
C) Aluminum alloy plate 1/8″ or greater
D) Stainless steel plate 1/8″ or greater
Correct answer: C
Rationale: AWS D1.1 applies to carbon and low‑alloy
steels; aluminum and other non‑ferrous alloys are
excluded.〖15†L20-L24〗
4. What is the minimum thickness of base metal that
an AWS D1.1 welder can work on?
A) 1/16″
B) 1/8″
,C) 3/16″
D) 1/4″
Correct answer: B
Rationale: AWS D1.1 requires a minimum thickness
of 1/8″ for welded joints under its provisions.〖
9†L24-L25〗
5. The term “WPS” in AWS D1.1 stands for:
A) Welding Position Specification
B) Welding Procedure Specification
C) Weld Process Standard
D) Welding Performance Statement
Correct answer: B
Rationale: WPS (Welding Procedure Specification)
defines the parameters and techniques for
producing acceptable welds.〖5†L30-L34〗
6. What is the function of a PQR (Procedure
Qualification Record)?
A) Certify welders
, B) Record test results proving a WPS produces
sound welds
C) Specify electrode type
D) Track welding costs
Correct answer: B
Rationale: A PQR validates that a WPS can produce
sound welds by documenting actual welding
conditions and test results.〖5†L45-L48〗
7. When a welder passes a groove weld test on
1‑inch thick plate, what is the maximum base metal
thickness the welder is qualified to weld per AWS
D1.1?
A) 1 inch
B) 1.5 inches
C) 2 inches
D) Unlimited
Correct answer: C
Rationale: When a welder qualifies on plate
thickness T, the qualified thickness range extends
