WFH-105 Semi-Automatic and Automatic Welding

252 hours


This course encompasses fundamental and intermediate levels of instruction in the use of the most common semi-automatic and automatic wire feed processes. These processes include Gas Metal Arc Welding (GMAW) including Pulse transfer, Flux Cored Arc Welding (FCAW) including Gas and Self-shielded, Metal Cored Arc Welding (MCAW), and Submerged Arc Welding (SAW). Students will be exposed to the operation of these processes as they relate to carbon steel, stainless steel, and aluminum. The theory component of this course includes the design and operation of various power sources and wire feed mechanisms as well as the different types of transfer modes commonly used. Instruction also includes shielding gases and their effect on weld metal transfer, weld metal chemistry, composition of electrode wires and associated fluxes.
