31442383Basic Gas Tungsten Arc Welding (GTAG)
Course Information
Description
Introductory course designed to provide the learner with a basic theoretical understanding of the Gas Metal Arc Welding process. Emphasis is placed on welding safety, equipment set-up/adjustment and developing manipulative skills using the Gas Tungsten Arc Welding Process. Welding skills are developed by performing a variety of weld joints in the flat and horizontal position on mild steel and stainless steel. Welding electrode identification, applications and shielding gasses are also addressed.
