WLD 131 GTAW (TIG) Plate

Lecture: 2 Lab: 6 Clinic: 0 Credits: 4

This course introduces the gas tungsten arc (TIG) welding process. Topics include correct selection of tungsten, polarity, gas, and proper filler rod with emphasis placed on safety, equipment setup, and welding techniques. Upon completion, students should be able to perform GTAW fillet and groove welds with various electrodes and filler materials.

Pre-requisite(s): DRE 097 or ENG 002
Course is typically offered in Fall and Spring.
Student Learning Outcomes (SLOs)
