Upon completion of this course, the student should have developed skills for the pressure vessel and nuclear piping fields.
Prerequisites: The student must have successfully passed the HIWT Shielded Metal Arc Welding Structural Advanced course. If this courses have not been completed, the following prerequisite tests are required:
Pass a guided bend test on 3/8” plate in the horizontal, vertical and overhead positions and pass a written test. Prerequisite testing charge is $150.00.
Course objective: To produce high quality single V-groove welds on 6” diameter schedule 80 carbon steel pipe in all positions. 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 understanding of uphill pipe welding and weld quality. This course helps to develop the welding skills necessary to produce quality multipass welds on 6”diameter schedule 80 mild steel pipe in the 2G and 5G positions, using E6010 and E7018 electrodes.
Testing: To pass this course, the student is required to take three written tests. The student also must pass visual and guided bend tests on welds produced in the 2G and 5G positions.
