Question 1
The primary purpose of structural welding special inspection is to:
A. Design welds for structural connections
B. Verify compliance with approved plans and welding codes
C. Approve paint colors and surface finishes
D. Install structural steel members
Answer: B Rationale: Welding inspectors are responsible for verifying that
welding work complies with approved plans, specifications, and applicable
welding codes. The special inspector does not design welds, approve finishes, or
perform installation work. The inspector's role is quality assurance and code
compliance verification.
Question 2
The primary welding code used for structural steel welding in the United States is:
A. AWS D1.1
B. NEC
C. IPC
D. NFPA 13
,Answer: A Rationale: AWS D1.1 is the Structural Welding Code for Steel, which
provides the standards for welding inspection, qualification, and fabrication of
steel structures. The NEC (National Electrical Code), IPC (International Plumbing
Code), and NFPA 13 (fire sprinkler systems) are unrelated to structural welding.
Question 3
The ICC Structural Welding Special Inspector certification is identified by which
designation?
A. S1
B. S2
C. 84
D. 49
Answer: B Rationale: ICC designates the Structural Welding Special Inspector
certification as S2. The exam consists of two modules covering code
requirements and plan reading.
Question 4
A weld is technically defined as:
A. A mechanical fastener used to join structural members
B. A localized joining process using heat, pressure, or both
C. A concrete anchor installation method
D. A roofing attachment system
Answer: B Rationale: Welding is a localized joining process that uses heat,
pressure, or both to create a coalescence of materials. Unlike mechanical
fasteners, welding creates a metallurgical bond between the joined members.
Question 5
,Which of the following must the special inspector verify during structural welding
inspection?
A. Furniture layouts and office arrangements
B. Welder qualifications and certifications
C. Paint colors and decorative finishes
D. Landscaping plans and site grading
Answer: B Rationale: The special inspector must verify that welders are properly
qualified to perform the specified work in accordance with AWS standards.
Furniture layouts, paint colors, and landscaping are not within the inspector's
scope of responsibility.
Question 6
A Welding Procedure Specification (WPS) provides:
A. Approved welding requirements and procedures for producing sound welds
B. Paint schedules and coating specifications
C. Plumbing and piping diagrams
D. Roofing and flashing details
Answer: A Rationale: The WPS documents specify the approved welding
procedures, including parameters, materials, and techniques required to
produce welds meeting code requirements. It provides detailed instructions for
the welder to follow.
Question 7
Groove welds are commonly used for:
A. Complete joint penetration (CJP) connections requiring full strength
B. Temporary tack welds only
C. Roofing repairs and flashing attachments
D. Paint system anchoring points
, Answer: A Rationale: Groove welds are designed for complete joint penetration
connections where the full cross-section of the joint is welded, providing
maximum strength. They are not used for temporary tack welds or non-
structural applications.
Question 8
Which welding process uses a consumable electrode that is continuously fed
through a gun and shielded by an external gas?
A. SMAW
B. GMAW
C. GTAW
D. SAW
Answer: B Rationale: Gas Metal Arc Welding (GMAW), commonly known as MIG
welding, uses a continuously fed consumable electrode and external shielding
gas. SMAW uses a stick electrode; GTAW uses a non-consumable tungsten
electrode; SAW uses granular flux shielding.
Question 9
SMAW stands for:
A. Shielded Metal Arc Welding
B. Surface Mount Arc Welding
C. Steel Metal Arc Welding
D. Standard Metal Arc Welding
Answer: A Rationale: Shielded Metal Arc Welding (SMAW) is a manual welding
process that uses a consumable electrode coated with flux to provide shielding.
It is also known as "stick welding" and is widely used in structural steel
fabrication.
