WELD-272 Advanced Welding Processes

Credits 4 / 6 Contact Hours
Pre-requisite: Placement into ACRD 080 ; WELD-168 and WELD-170. Note: Students must provide their own safety glasses, gloves, boots, welding jacket, and welding beanie for lab activities.
This course will examine the uses, operational characteristics, and power supply requirements of pulse welding equipment. The information will enable students to enhance their welding skills and techniques on carbon steel, stainless steel, and aluminum in various qualifying positions using GMAW and GTAW processes.
