Shipfitter Certification Performance Exam –
QUESTIONS AND VERIFIED ANSWERS WITH
RATIONALES JUST RELEASED
Summarized Exam Coverage
The Shipfitter Certification Performance Exam measures a candidate’s ability to safely perform structural
fitting, layout, blueprint reading, fabrication, alignment, cutting, and repair tasks used in shipbuilding
environments. Candidates are expected to demonstrate strong knowledge of measuring tools, fitting
tolerances, rigging practices, welding preparation, hull fairness, and shipyard safety procedures. The
exam emphasizes practical field performance, structural accuracy, safe work practices, and correct use
of fabrication equipment.
Shipfitter Certification Performance Exam –
1.
A shipfitter preparing to install a bulkhead notices the structure is slightly out of square during fit-up
procedures. What action should be taken first?
A. Force the structure into position using excessive tack welds
B. Verify measurements and correct alignment before welding
C. Begin final welding immediately to prevent movement
D. Remove all temporary bracing permanently
Answer: B
, Page 2 of 136
Rationale: Proper alignment and dimensional verification must occur before welding to prevent
distortion and structural inaccuracies.
2.
Which safety procedure is most critical before beginning hot work inside a confined ship compartment?
A. Increasing ventilation airflow and obtaining proper permits
B. Removing respiratory protection requirements
C. Disabling fire watch responsibilities
D. Eliminating atmospheric testing procedures
Answer: A
Rationale: Confined space hot work requires ventilation, atmospheric testing, and permit authorization
to ensure personnel safety.
3.

A shipfitter notices slag buildup along the cut edge after oxy-fuel cutting operations. What is the most
likely cause?
A. Incorrect cutting speed or improper torch adjustment
B. Reduced oxygen supply pressure only
C. Proper cutting tip operation
D. Excessive surface cleaning procedures
Answer: A
Rationale: Improper travel speed and incorrect torch settings commonly create slag accumulation on
cut edges.
4.
Which measuring tool provides the greatest accuracy for checking structural plate thickness during
fabrication?
A. Framing square
B. Tape measure
, Page 4 of 136
C. Micrometer
D. Chalk line
Answer: C
Rationale: Micrometers provide highly accurate measurements for thickness verification.
5.
A shipfitter preparing a weld joint notices excessive rust and paint contamination near the bevel area.
What should occur first?
A. Perform welding immediately to save production time
B. Clean the joint thoroughly before welding preparation
C. Increase tack weld spacing intentionally
D. Reduce root opening dimensions significantly
Answer: B
Rationale: Weld areas must be free of contaminants to ensure weld quality and structural integrity.
