Each welding process requires its own equipment, power source and filler metal (with or without gas
shield or flux). Therefore, the manual skills, set-up and deposition rate are all different. Each process
is suitable for certain types of joints and welding positions. This chapter briefly explains each process
in more general terms. There are several other welding processes that are not discussed here, but are
covered in depth in the following CWB Modules:
Module 4 Welding Processes and Equipment
Module 5 Power Sources for Welding
Module 6 Electrodes and Consumables
The types of welding joints and welding positions mentioned above can be found in Clause 10 of CSA
W59 “Welded Steel Construction (Metal Arc Welding)”. The electrode designations and classifications
can be found in the CSA W48-01 standard, which covers electrodes for various welding processes:
*CSA W48.1 Mild Steel Covered Arc Welding Electrodes
*CSA W48.2 Stainless Steel Electrodes
*CSA W48.3 Low-Alloy Steel Covered Arc Welding Electrodes
*CSA W48.4 Solid Mild Steel Filler Metals for Gas Shielded Arc Welding
*CSA W48.5 Mild Steel Electrodes for Flux Covered Arc Welding
*CSA W48.6 Base Mild Steel Electrodes and Fluxes for Submerged Arc Welding
