1.
Which statement best describes the primary scope of AWS
D1.1/D1.1M?
A. Welding of aluminum pressure vessels
B. Welding of reinforcing bars exclusively
C. Welding of commonly used carbon and low-alloy structural
steels
D. Welding of stainless-steel piping systems
Answer: C. Welding of commonly used carbon and low-alloy
structural steels
,Rationale: AWS D1.1/D1.1M is the Structural Welding Code—
Steel. Its scope addresses welded structures made from
commonly used carbon and low-alloy constructional steels. It
establishes requirements associated with structural welding,
including qualification, fabrication, inspection, and acceptance.
Aluminum structures, reinforcing bars, stainless steel, and
pressure piping are covered by other standards when
applicable. Selecting the correct governing code is fundamental
because qualification and acceptance requirements are code-
specific.
2.
A welding contractor is preparing a structural-steel project
governed by AWS D1.1. Which activity is specifically addressed
by the code?
A. Qualification of welding procedures and welders
B. Certification of building electricians
C. Calibration of concrete batching equipment
D. Design of electrical grounding systems
Answer: A. Qualification of welding procedures and welders
Rationale: Qualification is a central function of AWS D1.1. The
code establishes requirements for welding procedure
qualification and performance qualification of welders and
,welding operators. These requirements provide evidence that
the specified welding variables and personnel capabilities can
produce acceptable structural welds. The other activities are
outside the primary purpose of the structural welding code.
3.
What is the principal purpose of a Welding Procedure
Specification (WPS)?
A. To document the welder's employment history
B. To specify the controlled welding variables and requirements
for making the weld
C. To replace engineering drawings
D. To serve only as an inspection report after welding is
complete
Answer: B. To specify the controlled welding variables and
requirements for making the weld
Rationale: A WPS provides the welding instructions and
essential information necessary to produce a weld under
controlled conditions. Depending on the applicable qualification
route, it identifies variables such as welding process, base
metals, filler metal, joint details, electrical parameters,
preheat/interpass requirements, and other applicable
, conditions. A WPS is therefore a production-control document
rather than a personnel résumé or postweld inspection report.
4.
What is the primary distinction between a prequalified WPS
and a WPS qualified by testing?
A. A prequalified WPS never requires compliance with the code
B. A tested WPS can ignore the applicable base-metal
requirements
C. A prequalified WPS may be used without procedure
qualification testing when all applicable prequalification
requirements are satisfied
D. A tested WPS automatically qualifies every welding process
Answer: C. A prequalified WPS may be used without
procedure qualification testing when all applicable
prequalification requirements are satisfied
Rationale: Prequalification is a specific code pathway, not an
exemption from the code. A WPS can be considered prequalified
only when the applicable requirements governing materials,
joint details, welding processes, filler metals, positions, preheat,
electrical variables, and other relevant conditions are satisfied.
If the proposed procedure falls outside the permitted
prequalified limits, procedure qualification testing may be
