Introduction
,This examination assesses the candidate’s mastery of the AWS D1.1 Structural Welding Code—Steel, the globally
recognized standard for welding carbon and low-alloy structural steel. The primary purpose is to verify that inspectors,
engineers, fabricators, and welding professionals possess the knowledge required to ensure structural integrity, safety,
and code compliance in steel construction. The exam evaluates skills ranging from procedure and welder qualification
to fabrication tolerances, inspection criteria, and nondestructive examination. It employs multiple-choice and scenario-
based questions designed to simulate real-world decision-making. Candidates are tested on their ability to navigate the
code, apply acceptance criteria, and resolve compliance issues—skills essential for maintaining quality assurance in the
field.
SECTION ONE: QUESTIONS 1–50
Question 1
What is the primary material scope of AWS D1.1/D1.1M?
A. Aluminum alloys and stainless steels
B. Carbon and low-alloy structural steels
C. Cast iron and wrought iron
D. Copper-nickel alloys
,🟢 Correct Answer: B. Carbon and low-alloy structural steels
🔴 Explanation: AWS D1.1 is the Structural Welding Code for Steel, covering carbon and low-alloy steels used in
structural applications.
Question 2
Under AWS D1.1, who bears the primary responsibility for approving a Welding Procedure Specification (WPS)?
A. The welder performing the work
B. The Engineer or designated authority
C. The welding inspector only
D. The filler metal manufacturer
🟢 Correct Answer: B. The Engineer or designated authority
🔴 Explanation: The Engineer or designated authority is responsible for approving welding procedures to ensure
they meet project and code requirements.
Question 3
, What document provides the written instructions required to make a production weld?
A. Procedure Qualification Record (PQR)
B. Welding Procedure Specification (WPS)
C. Welder Performance Qualification (WPQ)
D. Material Test Report (MTR)
🟢 Correct Answer: B. Welding Procedure Specification (WPS)
🔴 Explanation: The WPS is the written document that provides specific directions for making a weld according to
qualified parameters.
Question 4
A Procedure Qualification Record (PQR) serves what primary purpose?
A. Documenting a welder's individual skill level
B. Recording the variables and test results of a qualified procedure
C. Authorizing a fabricator to begin production
D. Certifying an inspector's credentials
