scope:

This Standard prescribes requirements for the classification and certification of

(a) carbon steel covered electrodes for shielded metal arc welding (formerly CSA Standard W48.1);

(b) chromium and chromium-nickel steel covered electrodes for shielded metal arc welding. This includes electrodes designated for welding heat-resistant steels containing more than 1 1 Yo chromium and less than 50% nickel (formerly CSA Standard W48.2);

(c) low alloy steel covered electrodes for shielded metal arc welding (formerly CSA Standard W48.3);

(d) solid carbon steel filler metals for gas-shielded arc welding (formerly CSA Standard W48.4);

(e) carbon steel electrodes for flux- and metal-cored arc welding (formerly CSA Standard W48.5);

(f) fluxes and solid carbon steel electrodes for submerged arc welding (formerly CSA Standard W48.6); and

(g) fluxes and composite carbon steel electrodes for submerged arc welding (formerly CSA Standard W48.6).

Filler metals and allied materials covered by this Standard are classified according to one or more of the following requirements:

(a) chemical composition;

(b) usability characteristics;

(c) covering type (for covered electrodes);

(d) weld metal diffusible hydrogen (hydrogen-controlled classifications);

(e) mechanical properties of the weld metal (including heat treatment condition); and

(f) positions of welding for which electrodes are suitable.
