WLD 215 - Fabrication/Welding 4

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, assembly and final finishing. Also studied are concepts in ferrous metallurgy and their applications.

Prerequisite: WLD 112  and WLD 113  and WLD 114 . Second year standing or instructor consent or performance test and written examination.
