WLD 216 - Fabrication/Welding 5

12 Credit(s)

This course instructs in the skills and technology associated with fabrication of metal products. Welding practice is provided in wire drive, SMAW and GTAW processes. Fabrication skills taught include blueprint reading, metal layout, part preparation and assembly and final finishing. Also studied are concepts in ferrous metallurgy and their applications especially pertaining to welding of carbon and stainless steel.

Prerequisite: WLD 215 . Second year standing or instructor consent or performance test and written examination.
