WELD 208 - Gas Tungsten Arc (TIG) Welding


PROGRAM: Industrial Technology
CREDIT HOURS MIN: 3
LECTURE HOURS MIN: 1
LAB HOURS MIN: 4
DATE OF LAST REVISION: Fall 2022

This course provides students with a thorough knowledge of the gas tungsten arc welding (GTAW) process. This course also includes a detailed study of the techniques of making welds in all positions using the GTAW applications. The combination of lectures. labs and discussion provide additional background information essential to a qualified GTAW welder.

 1. Demonstrate safe practices involved in GTAW. [c

 2. Demonstrate proper inspection, setup, and breakdown of GTAW equipment. [e,f]

3. Identify and describe the function of each component of a GTAW station. [e,f]

4. Properly identify and assemble all components of the GTAW torch. [e,f]

5. Demonstrate proper safety procedure in removal and refitting of gas cylinders. [e,f]

6.   Identify GTAW electrodes and filler metals using the AWS electrode classification system. [e,f]

7. Explain the effects of DCEN, DCEP, and AC current on electrode life, surface cleaning, and weld characteristics. [e,f]

8. Identify proper shielding gases for GTAW. [e,f]

9. Properly prepare tungsten electrodes for welding. [e,f]

10. Properly prepare metals for welding. [e,f]

11. Identify and GTAW five (5) basic weld joints.  [e,f]

12. GTAW with Mild Steel, Stainless Steel, and Aluminum. [e,f]

13. GTAW in all positions with mild steel. [e,f]
