CSA W48 Electrode and Filler Metals Certification

CSA W48 provides requirements for the classification and certification of welding consumables by itself or in conjunction with gas mixtures or fluxes as applicable. The standard provides all requirements on chemical and mechanical properties of the electrodes and acceptable manufacturing tolerances. In addition, CSA Standard W48 requires the manufacturer to implement a quality management system that provides instruction on how to manufacture, inspect, pack, store, label and ship these welding consumables.
