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 Pipe 6G Position Uphill course. If this course has not been completed, the following prerequisite tests are required:
Pass a visual and guided bend test on a weld produced in the 6G position using E6010 and E7018 electrodes — and pass a written test. Prerequisite testing charge is $100.00.
Course objective: To produce quality single V-groove welds on 2-inch diameter schedule 80 and XX heavy wall carbon steel pipe in the 6G position. 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 pipe welding, weld quality, uphill pipe procedures and preheating and interpass heat treatments. This course helps to develop welding skills to produce quality multipass welds on 2-inch diameter schedule 80 and XX heavy wall mild steel pipe in the 6G position, using E6010 and E7018 electrodes.
Testing: To pass this course, the student is required to take two written tests. The student also must pass a visual and guided bend test on a weld produced in the 6G position on both schedule 80 and XX heavy wall, 2-inch pipe.
