CMAE 1568 - Gas Tungsten Arc Welding

Credits: 3

Course Description:

This course covers the safety hazards and applications for Gas Tungsten Arc Welding (GTAW) in the welding industry. Material covered will be power sources, setup, types of current, current selection, shielding gases, and torch types. Procedures and potential problems welding various metals (Aluminum, Stainless Steel, and Mild Steel) will be addressed in this course.
Applications for the process in different industries, as well as the use of back purging will be discussed. Welds will be made in the flat, horizontal, vertical and overhead positions. Written and fundamental tests will be completed in accordance with the American Welding Society (AWS) codes and standards.
Course Outcomes:
1. Demonstrate the proper use of Personal Protective Equipment (PPE) during welding.
2. Demonstrate safety habits consistent with industry standards and college policy.
3. Operate GTAW equipment according to industry standards and practices.
4. Differentiate GTAW setup requirements and techniques from other welding processes,
5. Evaluate the various types of power sources, types of current, and applications utilized in GTAW.
6. Demonstrate the different methods of adding filler metal when utilizing GTAW.
7. Examine the GTAW applications used in current industry practices,
8. Demonstrate proper electrode preparation for desired weld characteristics based on ferrous and nonferrous metals.
9. Demonstrate welds in the flat, horizontal, vertical, and overhead positions utilizing GTAW aligned with industy codes and practices.
10. (ILO: 2) Analyze the metallurgical properties of ferrous and nonferrous metals using industy recognized terminoloy.
