Preface

This is the second edition of CSA W48, Filler metals and allied materials for metal arc welding. It supersedes the first edition published in 2001.

1 Scope

1.1

This Standard specifies requirements for the classification and certification of
(a) carbon steel covered electrodes for shielded metal arc welding (SMAW);
(b) chromium and chromium-nickel steel covered electrodes for SMAW, including electrodes designated for welding heat-resistant steels containing more than 11% chromium and less than 50% nickel;
(c) low alloy steel covered electrodes for SMAW;
(d) wire electrodes and deposits for gas-shielded metal arc welding (GMAW) of non-alloy and fine-grained steels, as specified in Clause 1.2;
(e) carbon steel electrodes for flux-cored arc welding (FCAW) and metal-cored arc welding (MCAW);
(f) fluxes and solid carbon steel electrodes for submerged arc welding (SAW); and
(g) fluxes and composite carbon steel electrodes for SAW.

1.2
Wire electrodes and deposits for GMAW of non-alloy and fine-grained steels are classified and certified under this Standard using the designations and classification requirements specified in CAN/CSA-ISO 14341. The procedures and conditions for required tests, including radiographic test requirements, are specified in Clause 7.

1.3
The filler metals and allied materials covered by this Standard are classified in accordance with requirements based on one or more of the following criteria:
(a) chemical composition;
(b) usability characteristics;
(c) type of covering (for covered electrodes);
(d) diffusible hydrogen in weld metal (hydrogen-controlled classifications);
(e) mechanical properties of weld metal (including heat treatment condition); and
(f) positions of welding for which electrodes are suitable.
