Upon completion of this course, the student should be able to perform structural welding related to buildings and bridges – and production welding on light, medium and heavy assemblies.
Prerequisites: The student must have successfully passed the Hobart Institute of Welding Technology Gas Metal Arc Welding Basic (GMA011) course. If this course has not been completed, the following prerequisite test is required: Pass a 3/8-inch plate open root guided bend test in the horizontal, vertical down, and overhead positions, and a written test. Prerequisite testing charge is $150.00.
Course objective: To develop the ability to produce quality fillet and groove welds on carbon steel and aluminum using pulse or spray transfer. This course also develops skills for Welder, Arc (DOT 810.384-014).
Course content: This course provides training on pulse transfer other than the short-circuiting, which is covered in the Gas Metal Arc Welding course. The pulse transfer provides for high deposition rate for all position welding. This course also includes gas metal arc welding of aluminum.
Testing: To pass this course, the student is required to take one written test. The student also must pass one visual guided side bend test and two visual cut and etch tests on aluminum (vertical up and overhead). Pulse transfer will be used.
