CSA W59.2-18 Welded aluminum construction.
3 General requirements
3.1 Qualification requirements
3.1.1 Contractor
When mandated in the contract or in the governing design Standard,* all contractors performing work
under this Standard shall comply with CSA W47.2 for welded fabrications.
* Examples: CSA S6 and CSA S157.
3.1.2 Welding processes
This Standard covers the following welding processes:
a) gas metal arc welding (GMAW);
b) gas tungsten arc welding (GTAW);
c) plasma arc welding (PAW);
d) friction stir welding (FSW); and
e) stud welding (SW) by the arc and capacitor discharge.
Filler metals and allied materials for the various processes shall conform to the requirements in
AWS A5.10/A5.10M, except for stud welding, which shall conform to the requirements of Clause
of this Standard.
Other welding processes may be used with the approval of the engineer. Any welding process not covered directly by AWS A5.10/A5.10M or not written in this Standard shall be subject to the acceptance provisions of CSA W47.2.
Note: Clause 10 provides specific requirements for friction stir welding (FSW).
Stud welding procedures shall conform to the requirements of Clause 6 and their approval shall be based on satisfactory tests prescribed in Clause 6.
Aluminum base alloys to be welded under this Standard shall conform to the requirements of CSA HA
series or ASTM, in the following Aluminum Association alloy classifications:
a) Wrought alloys:
i) 1XXX: 1060, 1100;
ii) 2XXX: 2219;
iii) 3XXX: 3003, Alclad 3003, 3004, Alclad 3004;
iv) 5XXX: 5005, 5050, 5052, 5083, 5086, 5154, 5254, 5454, 5456, 5652;
v) 6XXX: 6005, 6005A, 6061, Alclad 6061, 6063, 6082, 6351; and
vi) 7XXX: 7005.
