WEL 277 — WEL 277
Offers the student the opportunity to develop skills in the Gas Tungsten Arc Welding process for mild steel pipe. It develops the skills necessary to produce quality open root groove welds, on 5" diameter schedule 80 mild steel pipe in the 2G and 5G positions, walking the cup technique to deposit the root and hot p ass, and the SMAW process with E7018 low hydrogen electrodes to complete the weld. An introduction to ER309 stainless steel welding in the 6G position is also presented. Weld quality will b e validated using guided bend tests. 5-week course (80 hr.) Prerequisite: WEL 270 (WELD 270)
Prerequisites: WEL 270, WELD 270
