Upon completion of the course, the student should be able to perform production and maintenance welding on mild steel and aluminum commonly used in fabrication and other industries.
Course objective: To be able to produce quality fillet and square groove welds on carbon steel and aluminum in the flat and horizontal 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 810.684-010) 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 and .125” and .25” aluminum, using direct and alternating current. In addition, material is presented on the metallurgy and welding characteristics of carbon steel and aluminum.
Testing: To pass this course, the student is required to take two written tests. The student also must pass a visual test on 11-gauge carbon steel welded in the horizontal position including a lap joint, t-joint and outside corner, and visual inspection and liquid penetrant test on a multi-pass .25” aluminum single v-groove butt joint welded in the flat position.
