Upon completion of the course, the student should have developed uphill pipe welding techniques and skills for the pressure vessel and nuclear piping fields. This process is also used for all utility work, nuclear and navy vessels.

Prerequisites: The student must have successfully passed the HIWT Gas Tungsten Arc Welding Basic course and Shielded Metal Arc Welding Pipe 6G Position Uphill course. If these courses have not been completed, the following prerequisite tests are required:

Pass a visual and guided bend test of a square groove weld on 11-gauge carbon steel plate in the flat position, using the gas tungsten arc welding process; and pass a visual inspection on 6-inch schedule 80 mild steel pipe welded in the 2G, 5G and 6G positions with backing rings, using the shielded metal arc welding process and E7018 low hydrogen electrodes, and pass a written test. Prerequisite testing charge is $200.00.

Course objective: To produce quality single v-groove welds on 6″ diameter schedule 80 carbon steel pipe in all welding positions 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 and stainless steel pipe. It provides training to develop welding skills to make welds on carbon steel open root, 6″ diameter schedule 80 steel pipe in the 2G, 5G, and 6G positions. It also uses the gas tungsten arc welding process with stainless steel filler material to deposit the root and second pass – and the shielded metal arc process to complete the weld.

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 6″ schedule 80 steel pipe in the 2G, 5G and 6G positions.
