Question 1
What is the primary scope of AWS D1.1/D1.1M?
A. Welding of pressure vessels and pressure piping
B. Welding of structural steel using commonly used carbon and
low-alloy constructional steels
C. Welding of aluminum aircraft structures
D. Welding of stainless-steel food-processing equipment only
Correct Answer: B. Welding of structural steel using
commonly used carbon and low-alloy constructional steels
Rationale: AWS D1.1/D1.1M is specifically a structural welding
code for steel. Its scope addresses welded structures fabricated
from commonly used carbon and low-alloy constructional
,steels. Pressure vessels, pressure piping, aluminum structures,
and specialized stainless-steel applications generally fall under
other applicable codes or specifications. The governing project
documents should always be checked to determine which
welding standard applies.
Question 2
A welding procedure is being prepared for a structural joint.
What is the principal purpose of a Welding Procedure
Specification (WPS)?
A. To document the welder's employment history
B. To establish the variables and requirements used to produce
an acceptable weld
C. To replace all inspection requirements
D. To identify the project's structural engineer
Correct Answer: B. To establish the variables and
requirements used to produce an acceptable weld
Rationale: A WPS provides the welding personnel with the
essential information needed to make the weld in accordance
with the applicable qualified procedure. Depending on the
applicable qualification route, this includes variables such as
welding process, base material, filler metal, joint details,
position, preheat or interpass requirements, electrical
,characteristics, and other applicable conditions. A WPS does not
replace inspection or engineering requirements.
Question 3
Which statement best describes a prequalified WPS?
A. It never needs to comply with the code
B. It is automatically acceptable for every structural steel
material
C. It may be used without procedure qualification testing when
all applicable D1.1 prequalification requirements are satisfied
D. It is a WPS prepared after a failed welder qualification test
Correct Answer: C. It may be used without procedure
qualification testing when all applicable D1.1 prequalification
requirements are satisfied
Rationale: Prequalification is a specific code-based route for
establishing that a welding procedure does not require
qualification testing when the procedure complies with all
applicable requirements. The term does not mean that the WPS
is exempt from the code. Joint details, materials, welding
processes, filler metals, preheat, welding parameters, and other
applicable requirements must remain within the permitted
limits.
, Question 4
A WPS is described as "prequalified." Which statement is most
accurate?
A. The WPS can contain any welding parameters selected by
the welder
B. The WPS must comply with the applicable prequalification
provisions of D1.1
C. The WPS can be used for any base metal regardless of
classification
D. The WPS does not need to identify the welding process
Correct Answer: B. The WPS must comply with the applicable
prequalification provisions of D1.1
Rationale: Prequalification is conditional, not unrestricted. The
WPS must satisfy the applicable code requirements for the
selected materials, welding process, joint configuration, filler
metal, preheat and interpass controls, and other relevant
variables. If the WPS falls outside the permitted prequalified
conditions, the procedure must be qualified by the applicable
qualification method rather than simply being labeled
prequalified.
