CSA W47.1 and CSA W59 Certification Exam
Practice Questions & Verified Answers (2026/2027 Update)
SECTION 1: CSA W59 SCOPE & GENERAL REQUIREMENTS
1. According to CSA W59, what is the minimum base metal thickness to which
the standard applies?
A. 1 mm
B. 2 mm
C. 3 mm (1/8 in)
D. 5 mm
Correct Answer: C. 3 mm (1/8 in). Rationale: CSA W59 applies to the welding of
base metals 3 mm (1/8 in) and thicker. Base metals thinner than 3 mm welded to
base metals 3 mm and thicker are also covered by AWS D1.3/AWS D1.3M in
conjunction with CSA W59 .
2. CSA W59 covers welding requirements for which type of steel construction?
A. Stainless steel only
B. Carbon and low-alloy welded steel construction
C. Aluminum construction only
D. Pressure vessel construction
,Correct Answer: B. Carbon and low-alloy welded steel construction. Rationale:
CSA W59 covers welding requirements for carbon and low-alloy welded steel
construction, with the exception of those types listed in Clause 1.2 .
3. What types of structures are covered in CSA Standard W59?
A. Only statically loaded structures
B. Only cyclically loaded structures
C. Both statically and cyclically loaded (repetitive loading) structures
D. Only pressure vessels
Correct Answer: C. Both statically and cyclically loaded (repetitive loading)
structures. Rationale: CSA Standard W59 covers statically- and cyclically-loaded
(repetitive loading) structures .
4. Which of the following welding processes is NOT included in CSA W59?
A. Shielded Metal Arc Welding (SMAW)
B. Submerged Arc Welding (SAW)
C. Laser Beam Welding (LBW)
D. Gas Metal Arc Welding (GMAW)
Correct Answer: C. Laser Beam Welding (LBW). Rationale: CSA W59 includes
SMAW, SAW, GMAW, FCAW, MCAW, ESW, EGW, and stud welding (SW) processes.
Laser beam welding is not included in this standard .
5. According to CSA W59, surfaces to be welded shall be free of contaminants
within what distance of any weld location?
A. 25 mm (1 in)
B. 50 mm (2 in)
C. 75 mm (3 in)
D. 100 mm (4 in)
, Correct Answer: B. 50 mm (2 in). Rationale: CSA W59 Clause 5.3.1 specifies that
surfaces to be welded shall be free, within 50 mm (2 in) of any weld locations, of
moisture and other foreign material that will prevent proper welding .
6. What does CSA W59 specify regarding stud welding?
A. Stud welding is not covered
B. Clause 6 has requirements for stud welding
C. Only Clause 10 covers stud welding
D. Stud welding requires separate certification
Correct Answer: B. Clause 6 has requirements for stud welding. Rationale: Yes,
Clause 6 of CSA Standard W59 has requirements for stud welding .
7. Does CSA Standard W59 contain provisions for pre-qualified joints?
A. No, all joints must be qualified individually
B. Yes, Clause 10 has details for the geometry of joints that are prequalified
C. Only for groove welds
D. Only for fillet welds
Correct Answer: B. Yes, Clause 10 has details for the geometry of joints that are
prequalified. Rationale: Yes, Clause 10 has details for the geometry of joints that
are prequalified, provided the welding procedures are followed .
8. What are the types of welds as specified in CSA Standard W59?
A. Groove, fillet, plug, or slot welds
B. Only groove and fillet welds
C. Only butt and lap welds
D. Only T-joints and corner joints
Correct Answer: A. Groove, fillet, plug, or slot welds. Rationale: Welds are
classified as groove, fillet, plug, or slot welds .
