1. Which statement best describes the certification commonly required
for structural welding inspection in Maryland construction projects
under building code special inspection provisions?
A. Maryland issues a mandatory state welding inspector license for all
inspectors
B. Structural welding inspection is typically performed under AWS
Certified Welding Inspector qualification aligned with building code
special inspection requirements
C. Only licensed engineers are permitted to inspect structural welds in
Maryland
D. Welding inspection is not regulated in Maryland construction
projects
Rationale: Structural welding inspection in Maryland is governed by
building codes such as the IBC, which require qualified special
inspectors, most commonly AWS Certified Welding Inspectors (CWI),
rather than a standalone state-issued welding inspector license.
2. Under Maryland building practice, structural welding inspection is
primarily required during which phase of construction?
, A. Only during design documentation review
B. Only after project completion
C. During fabrication and on-site construction when structural steel
welds are being made
D. Only during demolition of structures
Rationale: Structural welding inspection is conducted during
fabrication and construction to ensure welds meet code requirements
before structural elements are concealed or completed.
3. Which organization’s certification is most widely recognized for
structural welding inspectors working in Maryland?
A. American Society of Civil Engineers (ASCE)
B. American Welding Society (AWS)
C. Occupational Safety and Health Administration (OSHA)
D. National Institute of Standards and Technology (NIST)
Rationale: The AWS Certified Welding Inspector (CWI) credential is
the primary industry-recognized qualification used for structural
welding inspection under applicable codes.
4. Which code is most commonly referenced for structural steel welding
inspection in Maryland building projects?
A. AWS D1.1 Structural Welding Code—Steel
B. NEC Article 250
C. NFPA 72 Fire Alarm Code
D. ANSI Z87.1 Eye Protection Standard
Rationale: AWS D1.1 governs structural steel welding requirements
and is widely referenced by building codes for inspection criteria.
5. What is the main purpose of a structural welding inspector on a
Maryland construction site?
A. To design steel structures
B. To perform welding work directly
, C. To verify weld quality and compliance with applicable codes and
project specifications
D. To approve contractor payroll
Rationale: Structural welding inspectors ensure welds meet code and
specification requirements through visual inspection and
documentation review.
6. Which inspection method is most commonly used as the foundation of
structural welding inspection?
A. Visual testing (VT)
B. Radiographic testing only
C. Chemical analysis
D. Electrical load testing
Rationale: Visual inspection is the primary and most widely used
method for identifying weld discontinuities and verifying
workmanship.
7. What does AWS CWI certification primarily demonstrate?
A. Ability to operate welding equipment
B. Qualification to inspect and evaluate welds against applicable codes
C. Ability to design structural steel connections
D. Authority to issue building permits
Rationale: AWS CWI certification demonstrates competency in
inspecting welds and interpreting welding codes and standards.
8. In Maryland, who typically enforces structural welding inspection
requirements on construction projects?
A. Federal Aviation Administration
B. Local building authorities (counties or city jurisdictions)
C. Private insurance companies only
D. Welding equipment manufacturers
Rationale: Enforcement of structural inspection requirements is
