Question 1
Which statement best describes the primary scope of AWS
D1.1/D1.1M?
A. It applies exclusively to pressure vessels constructed from
carbon steel.
B. It establishes requirements for welding structural steel,
including fabrication, qualification, and inspection.
C. It governs only the design of welded aluminum structures.
D. It applies only to pipeline welding and pipeline inspection.
Correct Answer: B
Rationale: AWS D1.1/D1.1M is the Structural Welding Code—
Steel and establishes requirements associated with welded
structures fabricated from commonly used carbon and low-alloy
,structural steels. Its provisions address areas such as design,
WPS prequalification and qualification, welder qualification,
fabrication, inspection, stud welding, tubular structures, and
strengthening or repair of existing structures. It is therefore
much broader than a code limited to a particular welding
process or product such as pressure vessels or pipelines.
Question 2
When AWS D1.1 is incorporated into contract documents, what
is the general effect of that incorporation?
A. Only the visual inspection requirements automatically
become mandatory.
B. The code becomes advisory unless the fabricator voluntarily
adopts it.
C. The provisions of the code generally become requirements
unless specifically modified or exempted by the Engineer or
contract documents.
D. Only the welding procedure qualification requirements
become mandatory.
Correct Answer: C
Rationale: When D1.1 is stipulated in the contract documents,
its applicable provisions are requirements unless the Engineer or
contract documents specifically modify or exempt particular
,provisions. This distinction is important because D1.1 is a
contractual construction code when invoked by the project
documents, rather than merely a collection of optional
recommendations.
Question 3
A WPS is described as “prequalified” under AWS D1.1. What is
the most accurate interpretation?
A. Every welder using the WPS is automatically qualified for
every position and thickness.
B. The WPS may be exempt from procedure qualification
testing when all applicable prequalification requirements are
satisfied.
C. The WPS never needs to identify essential welding variables.
D. The WPS can be used for any base metal regardless of its
classification.
Correct Answer: B
Rationale: Prequalification provides a means by which a
Welding Procedure Specification can be accepted without
conducting a separate procedure qualification test, but only
when the WPS complies with all applicable prequalification
provisions. Prequalification of the WPS does not automatically
qualify individual welders, does not eliminate the need for
, required WPS information, and does not authorize unrestricted
combinations of base metals, filler metals, processes, positions,
thicknesses, or techniques.
Question 4
What is the principal purpose of a Welding Procedure
Specification (WPS)?
A. To document the welder's employment history
B. To establish the welding variables and requirements
necessary to produce an acceptable weld
C. To replace the contract drawings
D. To certify an inspector's qualifications
Correct Answer: B
Rationale: A WPS establishes the controlled welding variables
and instructions under which production welding is to be
performed. Depending on the applicable provisions, it addresses
items such as base metal, filler metal, welding process,
electrical characteristics, preheat, interpass temperature, joint
details, technique, and other required variables. A WPS is
therefore a production-control document, not a substitute for
engineering drawings or personnel certification.
