Question 1
What is the primary purpose of a Welding Procedure
Specification (WPS) in structural welding?
A. To document the welder's employment history
B. To establish the inspection schedule for a project
C. To specify the welding variables and conditions required to
produce the intended weld
D. To replace the need for welder performance qualification
Rationale: A WPS establishes the controlled welding variables
for a particular application, including items such as the welding
process, base metal, filler metal, joint configuration, position,
,preheat, and applicable technique requirements. Its purpose is
to provide a repeatable procedure for production welding. A
WPS does not serve as a résumé, inspection schedule, or
automatic substitute for personnel qualification.
Question 2
Under AWS D1.1, what is the fundamental distinction between
a prequalified WPS and a qualified WPS?
A. A prequalified WPS can be used without a qualified welder
B. A prequalified WPS meets specified code requirements
without requiring procedure qualification testing
C. A qualified WPS can only be used for fillet welds
D. A prequalified WPS does not have to be documented
Rationale: Clause 5 provides a pathway for prequalification
when the WPS complies with the applicable code requirements
and limitations. A procedure that does not qualify for
prequalification can instead be established through the
procedure qualification requirements of Clause 6. Personnel
qualification remains a separate requirement; prequalification
of the WPS does not automatically qualify the person
performing the weld.
Question 3
,Which clause of AWS D1.1 primarily addresses qualification of
welding procedures and welding personnel?
A. Clause 3
B. Clause 4
C. Clause 6
D. Clause 9
Rationale: Clause 6 is the Qualification clause. It addresses WPS
qualification and performance qualification for welders, welding
operators, and tack welders. Clause 5 addresses prequalified
WPSs, while Clauses 7 and 8 primarily address fabrication and
inspection.
Question 4
A welder performs a successful qualification test using a CJP
groove weld on a nontubular connection. Within the applicable
qualification limits, what broader weld types can this
qualification cover?
A. Only CJP groove welds
B. Only groove welds and fillet welds
C. CJP groove welds, PJP groove welds, fillet welds, plug
welds, slot welds, and tack welds
D. Only the exact joint configuration used during the test
, Rationale: AWS D1.1 provides an extent of qualification in
which qualification for a CJP groove weld on a nontubular
connection can qualify the welder for the listed broader
categories, subject to the applicable limitations of the code. The
qualification is therefore not automatically restricted to the
exact test-joint geometry.
Question 5
Which statement best describes the relationship between a
WPS and a Procedure Qualification Record (PQR)?
A. The PQR is the production instruction and the WPS is the test
record
B. The WPS specifies how welding is to be performed, while
the PQR documents qualification test results when procedure
qualification is required
C. The WPS and PQR are interchangeable documents
D. The PQR is required for every prequalified WPS
Rationale: The WPS is the controlled instruction used for
production welding. When a procedure must be qualified rather
than prequalified, the PQR records the actual variables used
during the qualification test and the resulting test data. A
prequalified WPS follows the code's prequalification provisions
and does not require a PQR merely because it is a WPS.
