Question 1
A structural steel project contract specifically invokes AWS
D1.1/D1.1M. A fabricator proposes to omit a D1.1 requirement
because the requirement is inconvenient for the shop's
established production procedure. No approved contract
modification has been issued. What is the appropriate
approach?
A. The fabricator may omit it if the weld visually appears
acceptable.
B. The fabricator may omit it if the welding engineer agrees
verbally.
C. The requirement remains applicable unless it is specifically
modified or exempted by the appropriate project authority or
,contract documents.
D. The requirement may automatically be omitted when an
alternative welding process is used.
Rationale: When D1.1 is invoked by the contract documents, its
applicable provisions form part of the governing welding
requirements. A shop preference does not override the code.
Any permitted modification or exemption must come through
the appropriate contractual or engineering authority rather
than being made unilaterally by production personnel. This
distinction is especially important on an open-book examination
because the governing documents determine which code
requirements are mandatory for the particular project.
Question 2
Which statement best describes the primary purpose of a
Welding Procedure Specification (WPS)?
A. To document only the welder's personal experience.
B. To establish the controlled welding variables and
requirements used to produce a weld meeting the specified
requirements.
C. To replace all inspection records after welding is completed.
D. To establish the structural design loads for the connection.
,Rationale: A WPS provides controlled instructions for
performing a weld, including the applicable process and
essential welding variables required by the governing
qualification provisions or prequalification provisions. It is not
simply a record of who performed the weld. Nor does it replace
design documents or inspection records. A properly controlled
WPS helps ensure that production welding is performed within
the qualified or prequalified range.
Question 3
A WPS is identified as prequalified. What is the most important
implication?
A. Every welder using it is automatically qualified for every
welding position.
B. No inspection is required because the WPS is prequalified.
C. The WPS can be used without procedure qualification
testing only when all applicable prequalification requirements
and limitations are satisfied.
D. The WPS can be used regardless of base-metal or electrode
limitations.
Rationale: Prequalification is conditional, not a blanket
exemption from the code. A prequalified WPS must conform to
the applicable requirements governing such matters as base
, materials, joint details, welding process, consumables,
parameters, preheat/interpass requirements, and other
applicable limitations. If any required condition falls outside the
permitted range, the procedure may require qualification rather
than simply being treated as prequalified.
Question 4
A welder is qualified for a particular process and range of
variables. The employer now wants the welder to perform
production welding using a different welding process. What
should be determined first?
A. Whether the welder has more than five years of experience.
B. Whether the weld will receive visual inspection.
C. Whether the existing performance qualification covers the
proposed welding process and applicable variables.
D. Whether the new process uses the same shielding gas.
Rationale: Welder performance qualification is process- and
variable-dependent. Experience alone does not extend a
qualification beyond its permitted range. The fact that both
processes produce fusion welds or use similar shielding gases
does not make them interchangeable. The applicable
qualification requirements must be checked to determine
