Course objective: To be able to produce quality fillet and square groove welds on thin carbon steel, stainless steel and aluminum in the flat, horizontal and vertical positions, using the gas tungsten arc welding process. This course also develops skills for Welder, Arc (DOT 810.384-014), Production Line Welder (DOT 819.684-010), Tack Welder (DOT 810.684010) and the Arc Welding portion of Combination Welder (DOT 819.384-010).

Course content: This course provides the student with a thorough technical understanding of gas tungsten arc welding, arc characteristics and welding safety. It provides training to develop the skill necessary to make quality gas tungsten arc welds on 16 and 11 gauge mild steel, .060-inch and .062-inch gauge stainless steel and .125-inch aluminum, using both direct and alternating current. In addition, material is presented on the weld characteristics of carbon steel, stainless steel and aluminum. Information on pulsed current is included to prepare the student for more detailed applications of pulsed current used in gas tungsten arc welding pipe.

Testing: To pass this course, the student is required to take two written tests. The student also must pass a visual guided bend test in the flat position on mild steel, and visual tests on stainless steel and aluminum.
