Upon completion of the course, the student should have developed skills for pipe welding in various industries and applications including power generation, refineries, process piping, vessel manufacturing, utility work and others.
Prerequisites: The student must have successfully passed the HIWT Gas Tungsten Arc Welding Basic course and Shielded Metal Arc Welding 6” Pipe 6G Uphill course. If these courses have not been completed, the following prerequisite tests are required:
Pass a visual test on 11-gauge carbon steel welded in the horizontal position including a lap joint, T-joint and outside corner using the gas tungsten arc welding process; and pass a visual inspection on 6” schedule 80 mild steel pipe welded in the 6G position with backing ring, using the shielded metal arc welding process and E7018 low hydrogen electrodes and pass a written test. Prerequisite testing charge is $150.00.
Course objective: To be able to produce quality single v-groove welds on 2” and 6” diameter schedule 80 carbon steel pipe in the 6G position using the gas tungsten arc welding process and shielded metal arc welding process. Quality is determined through visual inspection and mechanical testing. This course also develops skills for Welder, Arc (DOT 810.384-014).
Course content: This course provides the student with a thorough technical understanding of joint designs, programmable gas tungsten arc welding equipment and methods of welding carbon steel pipe. It provides training to develop welding skills to make welds on carbon steel open root, 2” and 6” diameter schedule 80 steel pipe in the 6G position.
Testing: To pass this course, the student is required to take two written tests. The student also must pass visual and guided bend tests on welds produced on 2” and 6” schedule 80 steel pipe in the 6G position.
