WELD 120: Beginning Welding and Metal Fabrication II

Credits 15
Quarter Offered

Continuation of WELD 110. Includes the shielded metal arc welding (SMAW) process, electrodes, oxy-acetylene flame cutting, introduction to plasma and carbon arc cutting, gouging, and the fundamentals of metallurgy. Learn to layout, cut, prepare, fit-up, and weld together metal to repair parts and fabricate projects using SMAW. This class may include students from multiple sections.

This class has a $200 welding lab supplies course fee.
