1. Which of the following best describes the role of a Structural Welding
Special Inspector under the International Building Code (IBC) Chapter 17?
A. Designs welded connections for structural steel members
B. Performs fabrication of structural steel welds on-site
C. Verifies that welding is performed in accordance with approved plans,
specifications, and applicable codes, including inspection and
documentation of compliance
D. Issues welding procedures and qualified welder certifications for
contractors
The Structural Welding Special Inspector is responsible for observing and
verifying that welding work complies with approved construction
documents and code requirements, rather than designing or performing
welding work. Their primary function is quality assurance through
inspection, testing oversight, and reporting.
2. In Maryland, what is the primary regulatory approach to structural
welding inspection requirements under building codes?
A. Maryland issues a mandatory state welding inspector license
B. Welding inspection is not regulated in any form in Maryland
,C. Maryland adopts the International Building Code (IBC) through the
Maryland Building Performance Standards, which requires special
inspection of structural welding where applicable
D. Only federal OSHA standards apply to welding inspection on construction
sites
Maryland follows the Maryland Building Performance Standards, which
adopt the IBC. The IBC requires special inspection of structural welding in
regulated construction types, meaning inspection is code-driven rather
than governed by a separate state licensing system.
3. Which credential is widely recognized in Maryland and across the U.S.
as evidence of qualification for structural steel welding inspection?
A. OSHA 10-hour Construction Safety Card
B. NICET Highway Construction Level I
C. AWS Certified Welding Inspector (CWI)
D. ACI Concrete Field Testing Technician Grade II
The AWS CWI certification is the industry-standard credential used to
demonstrate competency in welding inspection, especially where IBC
Chapter 17 special inspections require qualified personnel.
4. Under ICC Structural Welding Special Inspector responsibilities, which
task is included?
A. Approving shop drawings and engineering calculations
B. Verifying material identification and ensuring weld materials match
approved specifications
C. Supervising all structural steel erection activities
D. Certifying structural welders for employment eligibility
The inspector is responsible for verifying that materials such as base
metals and filler metals conform to specifications, ensuring compliance
with approved plans rather than performing design or supervisory
contractor roles.
, 5. What is the typical exam structure for the ICC Structural Welding
Special Inspector certification (S2)?
A. Oral exam only with field demonstration
B. 50-question closed-book exam
C. Approximately 90 multiple-choice questions with a timed, open-book
format
D. Practical welding test in a certified welding booth
The S2 exam is a standardized ICC certification exam consisting of multiple-
choice questions designed to evaluate knowledge of codes, plans, and
inspection procedures, and it is typically open-book.
6. Which prerequisite is commonly required before obtaining full
Structural Welding Special Inspector certification in ICC Category S2?
A. State of Maryland journeyman welder license
B. NICET Level III certification in structural steel
C. Completion of Structural Steel and Bolting Special Inspector certification
(S1)
D. OSHA 30-hour Construction Safety certification
ICC requires foundational certification in structural steel and bolting (S1)
before advancing to structural welding (S2), ensuring inspectors
understand steel construction systems before welding-specific inspection.
7. What is the main purpose of special inspections in structural welding
under the IBC?
A. To replace contractor quality control programs
B. To perform design validation of welded connections
C. To provide independent verification that construction work complies
with approved documents and code requirements
D. To approve contractor payment applications
, Special inspections exist to provide independent oversight and verification
that critical structural elements, such as welds, are constructed in
accordance with approved plans and safety standards.
8. Which of the following best describes Maryland’s licensing
requirement for welding inspectors?
A. Maryland issues a mandatory statewide welding inspector license
B. Only engineers may legally perform welding inspection in Maryland
C. Maryland does not require a state welding inspector license;
qualification is typically demonstrated through ICC, AWS CWI, or
equivalent credentials under code requirements
D. Welding inspection is restricted exclusively to federal inspectors
Maryland does not maintain a specific state license for welding inspectors;
instead, qualification is determined by building officials using recognized
certifications such as AWS CWI or ICC credentials under IBC requirements.
9. What is the primary responsibility when a structural welding special
inspector identifies a deviation from approved plans?
A. Immediately halt all construction permanently
B. Modify the engineering design to match field conditions
C. Notify the contractor and, if unresolved, escalate to the design
professional and building official
D. Approve the deviation if it is structurally acceptable
Inspectors must follow a formal reporting chain when deviations occur,
beginning with contractor notification and escalating to engineers and
building officials if corrections are not made.
10. Which code standard is most commonly referenced for
structural welding inspection criteria in the U.S. building code
framework?
A. ASTM C94
B. AASHTO LRFD Bridge Design Specifications
