Course Overview

Gas Metal Arc Welding (GMAW) is the most common industrial welding process and welds steels and aluminum faster than other welding processes. Students of this course will be able to describe and demonstrate the GMAW process.

Gas metal arc welding (GMAW) welding is a process where an electric arc forms between a consumable wire electrode and metals, heating the metals and causing them to melt and join. GMAW, also known as Metal Inert Gas (MIG) welding, feeds a shielding gas and a wire electrode through the welding gun, which avoids contaminants in the air. As such, GMAW is rarely used outdoors.

Upon successful completion of this course, students will be able to describe the types of power sources, machine settings, and maintenance requirements for GMAW. Students will also be able to describe the types of filler wires, shielding gases, and process applications.
Those who successfully complete this course will be able to demonstrate welding on various thicknesses of mild steel using conventional GMAW power sources and mini MIG units in the shop component of the course.
