WELD 122 - Flux Core Arc Welding

Credits: 1-6
LAB hours per week: 12
Introduce students to welding safety, industry practices, and Flux Core Arc Welding in a laboratory setting. Students will learn, practice, and apply skills needed for the safe operation of both self-shielding, and dual shielded FCAW, including the selection of correct parts, tools, and polarities to operate each process. Students will prepare projects to weld using basic blueprint reading skills. Lab practice will be completed while employing professional, ethical, and safe welding shop behavior.
Corequisite(s): Student is required to enroll in WELD 102 , WELD 112 , and WELD 122 .
Course Outcomes:
