1.
What is the primary scope of AWS D1.1/D1.1M?
A. Welding of pressure vessels and pressure piping
B. Welding of aluminum aircraft structures
C. Welding of structures fabricated from commonly used
carbon and low-alloy structural steels
D. Welding of stainless-steel food-processing equipment
Answer: C. Welding of structures fabricated from commonly
used carbon and low-alloy structural steels
AWS D1.1/D1.1M is specifically intended for welded structures
made from commonly used carbon and low-alloy constructional
steels. Its scope addresses structural design, fabrication,
,qualification, inspection, stud welding, tubular structures, and
repair. Pressure vessels, aluminum structures, and other
specialized applications are governed by other standards unless
specifically incorporated into a project.
2.
Which clause of AWS D1.1 primarily addresses prequalification
of Welding Procedure Specifications?
A. Clause 4
B. Clause 5
C. Clause 6
D. Clause 8
Answer: B. Clause 5
Clause 5 establishes the requirements under which a Welding
Procedure Specification can be considered prequalified. A
prequalified WPS does not eliminate the need to follow the
applicable code requirements; rather, it permits the WPS to be
exempt from the specific WPS qualification testing requirements
when all applicable prequalification conditions are satisfied.
3.
,A contractor proposes to use a WPS that does not satisfy the
applicable prequalified requirements. What is the fundamental
consequence?
A. The WPS automatically becomes prequalified after the first
production weld
B. The WPS may need qualification testing before being used
under the code
C. The welder's qualification automatically qualifies the WPS
D. Visual inspection alone qualifies the WPS
Answer: B. The WPS may need qualification testing before
being used under the code
Prequalification is an exemption from WPS qualification testing
only when the prescribed requirements are met. If the proposed
procedure falls outside those requirements, it cannot simply be
treated as prequalified. The applicable qualification provisions
must then be followed to demonstrate that the procedure can
produce an acceptable weld with the required properties.
4.
Which clause contains the principal requirements for
qualification of WPSs and welding personnel?
A. Clause 3
B. Clause 5
, C. Clause 6
D. Clause 10
Answer: C. Clause 6
Clause 6 addresses qualification. It includes requirements for
WPS qualification as well as performance qualification of
welding personnel, including welders, welding operators, and
tack welders. This distinction is important because qualifying a
procedure and qualifying an individual are separate code
functions.
5.
Why is a qualified WPS not, by itself, sufficient authorization for
any welder to perform production welding?
A. A WPS only applies to tack welds
B. The WPS establishes procedure requirements, while the
individual must also satisfy applicable performance
qualification requirements
C. WPS qualification applies only to inspectors
D. The WPS eliminates all personnel qualification requirements
Answer: B. The WPS establishes procedure requirements,
while the individual must also satisfy applicable performance
qualification requirements
