2. Catalog Description:

Gas tungsten arc welding. This is the second in a series of courses which teach the student the operation and application of gas tungsten arc welding (GTAW). The student selects proper current, prepares metal, and makes satisfactory welds. The course includes advanced welds on ferrous and non-ferrous metals as well as on pipe. A laboratory fee is required.

Minimum Grade Required

3. Prerequisites: WELD 130

Corequisites:

Other: Or permission of the Instructor or Program Coordinator

4. Learning Outcomes

Upon successful completion of the course the student will be able to:

· Explain the theory and applications of the Gas Tungsten Arc Welding (GTAW) process for pipe welding

· Select the proper welding power source, polarity, shielding gas, flow rate, tungsten electrode type and diameter, nozzle size, and filler metal required to produce an acceptable weld on pipe

· Assemble and adjust all the variable required to produce an acceptable weld on ferrous and non-ferrous metals and on pipe

· Prepare a tungsten electrode for welding for welding with AC or DC

· Prepare metals and pipe for welding and perform acceptable welds on all types of joints in all positions

· Identify all of the common potential safety hazards involved when using the GTAW process in a working environment and describe ways of safely dealing with these hazards
