CSA W59-18 Test Questions and Already
Solved Solutions 2026-2027 Updated.
CSA W59 - Answer Welded Steel Construction using Metal Arc Welding
CSA W59
Scope - Answer Covers welding requirements for any type of welded steel construction with
the following exception.
- does not apply to pressure vessels or to structures governed by special codes such as Lloyds,
API, ASME or AWWA.
- does not cover stainless steel.
*Includes provisions for SMAW, SAW, GMAW, FCAW, MCAW, ESW (Electro Slag welding), EGW
(Electro Gas welding) and SW (stud welding) welding processes.
CSA W59
Jurisdiction - Answer Steel Buildings, Bridges, Machinery, Cranes, Rail and Road Vehicles,
Storage Tanks, Mobile Drilling Units and Steel Fixed Offshore Structures.
*Linked with CSA W47.1 and CSA W48.
CSA W59
Administration - Answer All contractors performing work under this standard shall be certified
for welding fabrications when so stipulated in the governing design standard.
-In the absence of specific requirements in the governing design standard, the fabricator shall,
at the option of the engineer, either;
(a) Be certified under CSA W 47.1 or
(b) Provide evidence that he can produce the required welded fabrication to the engineer.
CSA W59
Welding Procedure Qualification - Answer The selection of the type of groove, the geometry
of preparation, the welding process and the related welding procedures shall be the
responsibility of the contractor's engineer and subject to the approval of the engineer.
Has a number of prequalified welding procedures.
CSA W59
Area of Interest to Welders - Answer -The welder, w/o and the welding consumables must be
adequately protected from the environment.
-The welder or w/o shall be able to work in reasonable comfort.
, -Welding should not be done below -18 C (0 F).
-Welds should conform to the engineer's specifications.
-All electrodes should be protected and stored so that their specified properties and
characteristics are not adversely affected.
-Surfaces and edges shall be smooth and uniform. Free from cracks, fins, scale, slag, rust, paint,
grease, moisture and other foreign material.
CSA W59
Performance Qualification Test Requirements - Answer There are no testing requirements but
because it is directly linked to Code CSA W47.1, most contractors who are fabricating to CSA
W59 are certified to CSA W 47.1.
CSA Standard W59 covers the welding requirements for what type of steel construction? -
Answer (Cl. 1.1, 1.2) The welding requirements of CSA W59 can be applied to carbon and low-
alloy steel construction, except where other special codes such as those of the API, ASME, or
AWWA govern.
(Cl. 1.4) This Standard is not intended for use with steels having a minimum specified yield
strength over 700MPa (100,000 psi)
What types of structures are covered in CSA Standard W59? - Answer (Cl. 1.1) CSA Standard
covers Statically- and cyclically- loaded (Repetitive loading) Structure. Clause 11 deals with
provisions that are applicable to statically loaded structures only and Clause 12 deals with
provisions that are applicable to cyclically-loaded structures only. The provisions of Clause 3 to
10 are applicable to all structures.
What is the definition of low hydrogen? - Answer Low hydrogen - A term applied to
consumables manufactured to deposit weld metal having a specified maximum limit to the
diffusible hydrogen content or to a process having inherently low diffusible hydrogen levels.
Who is the engineer as described in CSA Standard W59? - Answer Engineer - The
professionally qualified person representing the regulatory authority or the purchaser.
What are the requirements for the certification of contractors? - Answer (Cl. 3.1.1) When
mandated in the contract or in the governing design standard*, all contractors performing work
under this Standard shall comply with CSA Standard W47.1 for welded fabrications.
*Examples: CSA S6 and CSA S16.
Which welding processes are covered in CSA Standard W59? - Answer (Cl. 3.1.2.1) This
standard covers the SMAW, SAW, GMAW, GTAW, FCAW, MCAW, ESW, EGW, and SW processes.
