70 CLOCK HOURS
Prerequisites: The student must have completed the Hobart Institute of Welding Technology’s Gas Tungsten Arc Welding 2” Pipe (GTA108) course. If the student has not completed the above course, skill must be demonstrated by successfully completing the following tests:
The individual must pass a written test. Following successful completion of the written test, the student must pass a visual and destructive test of a single v-groove weld butt joint on 2” schedule 80 pipe in the 5G position using gas tungsten arc welding process. The joint must be completed using the “cup walking” method. Prerequisite testing charge is $50.00.
Course Objective: To be able to produce quality single v-groove welds on 2-inch diameter schedule 80 mild steel and stainless steel pipe in the 6G position.
Course Content: This course provides the student with a thorough understanding of the preparation, weldability and methods of welding stainless steel and mild steel pipe using the gas tungsten arc welding process. The students will develop the necessary skills to produce quality single v-groove welds on 2-inch diameter schedule 80 mild steel and stainless steel pipe in the 6G position with purge. The student will also have the opportunity to develop skills in welding dissimilar metals using the GTAW process.
Testing: To pass this course, the student is required to take one written test. The student must also pass visual and guided bend tests and/or radiographic testing on a 6G mild steel pipe and a 6G stainless steel pipe in the 6G position.
