Questions
1.
What is the primary scope of AWS D1.1/D1.1M?
A. Welding of aluminum pressure vessels
B. Welding of stainless-steel piping systems
C. Welding of structural assemblies made from commonly used
carbon and low-alloy steels
D. Welding of aerospace flight hardware
Correct Answer: C. Welding of structural assemblies made
from commonly used carbon and low-alloy steels
Rationale: AWS D1.1/D1.1M is the Structural Welding Code—
Steel. Its scope addresses welded steel structures fabricated and
,erected using commonly used carbon and low-alloy
constructional steels. It is therefore fundamentally different
from codes intended specifically for aluminum, pressure vessels,
piping, or aerospace hardware. The code is applied when its
requirements are invoked by the governing contract documents,
specifications, or other applicable requirements.
2.
A project specification invokes AWS D1.1 but explicitly modifies
one of its requirements. Which requirement governs that
specific situation?
A. The original D1.1 requirement always overrides the contract
B. The modified requirement stated by the Engineer or contract
documents, as permitted by the code
C. The welder may select whichever requirement is easier to
satisfy
D. The fabricator's internal WPS automatically overrides the
project specification
Correct Answer: B. The modified requirement stated by the
Engineer or contract documents, as permitted by the code
Rationale: D1.1 establishes a framework for structural welding,
but its general provisions recognize that the Engineer or
contract documents may specifically modify or exempt
,provisions where permitted. A fabricator cannot independently
override the governing contract requirements simply by using
an internal WPS. The applicable project documents must
therefore be reviewed before determining exactly which D1.1
provisions apply.
3.
Which D1.1 clause primarily addresses the design of welded
connections?
A. Clause 3
B. Clause 4
C. Clause 6
D. Clause 8
Correct Answer: B. Clause 4
Rationale: Clause 4 addresses the design of welded connections.
In the 2025 edition, AWS made several design-related changes,
including clarification of base-metal and filler-metal strength
requirements, provisions involving toughness and matching
filler metals, LRFD provisions, and a new table addressing
available strength of welded joints. A person performing an
open-book examination should therefore go directly to Clause 4
for design questions.
, 4.
Which clause is primarily associated with prequalification of
welding procedure specifications?
A. Clause 4
B. Clause 5
C. Clause 7
D. Clause 9
Correct Answer: B. Clause 5
Rationale: Clause 5 addresses prequalification of Welding
Procedure Specifications, commonly abbreviated WPSs. A
prequalified WPS is not simply a document created by the
contractor; it must satisfy the applicable prequalification
requirements of the code. The 2025 edition revised several
provisions in Clause 5, including filler-metal strength
requirements and the organization of the prequalified WPS
tables.
5.
What is the fundamental distinction between a prequalified
WPS and a WPS requiring qualification?
A. A prequalified WPS never needs to identify welding variables
B. A prequalified WPS must satisfy the applicable D1.1
