CSA Standard W59 covers the welding requirements for what type of steel construction? - correct
answer -The welding requirements of CSA Standard W59 can be applied to carbon and low-alloy
welded steel
What types of structures are covered in CSA Standard W59? - correct answer -CSA Standard W59
covers statically- and cyclically-loaded (repetitive loading) structures.
What is a low-hydrogen electrode? - correct answer -A low-hydrogen electrode is an electrode that
deposits weld metal with a specified maximum limit of diffusible hydrogen.
What are the requirements for contractor certification? - correct answer -When mandated in the
contract or in the governing design Standard*, all Contractors performing work under this Standard
must be certified to CSA W47.1 for welded fabrications.
What welding processes are covered in CSA Standard W59? - correct answer -This standard covers the
SMAW, GMAW, GTAW, MCAW, FCAW, SAW, ESW, EGW and SW processes.
Does CSA Standard W59 specify requirements for stud welding? - correct answer -Yes, Clause 6 has
requirements for stud welding.
Does CSA Standard W59 contain provisions for pre-qualified joints? - correct answer -Yes, Clause 10
has details for the geometry of joints that are prequalified, provided
the welding procedures
What base metals can be welded under CSA Standard W59? - correct answer -Welding Supervisor - the
company's designated person(s)
directly responsible for ensuring that qualified tack welders, welders, and welding operators weld in
accordance with approved or accepted welding procedure data sheets in the shop and the field.

The requirements for welding symbols are specified in what standard? - correct answer -Welding
symbols shall be as shown in AWS Standard A2.4, together with the additional conventions developed
for CSA Standard W59 and shown in Annex D of CSA Standard W59.
What information should be given on a design drawing? - correct answer -A design drawing should
contain:
information for preparation of detail and erection drawings;
the effective throat thickness shall be defined, if there are partial penetration groove welds.
What typical welding information would you expect to find on an erection or detail drawing? - correct
answer -A) location, type, size and length of all welds:
B) distinguish between shop and field welds;
C) groove depths and joint preparations, if there are partial penetration joints,together with the position
of welding;
D) any notes required, e.g. welding sequence, control of distortion, etc..
What are the types of welds as specified in CSA Standard W59? - correct answer -Welds are classified
as groove, fillet, plug or slot welds.
What is a complete joint penetration (CJP) groove weld? - correct answer -A CJP groove weld is one
that has complete penetration and fusion of weld and
base metal throughout the thickness of the joint.
What is a partial joint penetration groove weld? - correct answer -A partial joint penetration groove
weld is defined as one having
joint penetration less than complete
Does CSA Standard W59 allow for the use of intermittent groove welds? - correct answer -No. Groove
welds must be continuous for the full length of the joint or as otherwise permitted by the Engineer.
