Questions
1. What is the primary scope of AWS D1.1/D1.1M?
A. Welding of pressure vessels exclusively
B. Welding of aluminum aircraft structures
C. Welding of commonly used carbon and low-alloy structural
steel structures
D. Welding of stainless-steel piping systems
Correct Answer: C. Welding of commonly used carbon and
low-alloy structural steel structures
AWS D1.1/D1.1M is the Structural Welding Code—Steel. Its
scope addresses requirements for fabricating and erecting
welded steel structures made from commonly used carbon and
low-alloy constructional steels. It is not a general-purpose code
covering every welding application. Other AWS codes address
,specialized materials or applications, so the applicable
governing code must always be established before welding
work begins.
2. When AWS D1.1 is specified by the contract documents,
which statement best describes its application?
A. Only the visual inspection requirements become mandatory
B. All applicable provisions become requirements unless
specifically modified or exempted by the Engineer or contract
documents
C. Only the welder qualification requirements apply
D. The fabricator may select which provisions to follow
Correct Answer: B. All applicable provisions become
requirements unless specifically modified or exempted by the
Engineer or contract documents
When D1.1 is invoked by the contract, its applicable
requirements govern the covered welding work. The code also
recognizes that the Engineer or contract documents can
specifically modify or exempt particular provisions. This
distinction is important because simply using a D1.1-based WPS
does not mean the organization can arbitrarily disregard other
applicable code requirements.
,3. Which AWS D1.1 clause primarily addresses the design of
welded connections?
A. Clause 2
B. Clause 3
C. Clause 4
D. Clause 9
Correct Answer: C. Clause 4
Clause 4 addresses the design of welded connections.
Understanding the organization of D1.1 is important because
the code separates general requirements, references,
terminology, design, prequalification, qualification, fabrication,
inspection, and other subjects. A welder or inspector should
know where a requirement originates rather than relying on
memory alone.
4. What is the principal purpose of a Welding Procedure
Specification (WPS)?
A. To document the welder's employment history
B. To provide the welding variables and instructions required to
produce the specified weld
C. To replace all inspection records
D. To establish the structural engineer's professional license
, Correct Answer: B. To provide the welding variables and
instructions required to produce the specified weld
The WPS establishes the controlled welding parameters and
essential information necessary for producing an acceptable
weld. Depending on whether the WPS is prequalified or
qualified by testing, its supporting basis is different. A WPS is
therefore a fabrication-control document, not merely an
administrative form.
5. A WPS is described as “prequalified.” What does that
designation generally mean?
A. Every welder can use it without qualification
B. The WPS meets the applicable code requirements without
requiring procedure qualification testing, provided all
prequalification requirements are satisfied
C. The procedure has been approved by every structural
engineer
D. The WPS can be used on any base metal regardless of its
classification
Correct Answer: B. The WPS meets the applicable code
requirements without requiring procedure qualification
testing, provided all prequalification requirements are
satisfied
