Upon completion of the course, the student should have developed downhill pipe welding techniques for the service transmission piping fields.
Prerequisites: The student must have successfully passed the HIWT Shielded Metal Arc Welding 6″ Pipe 6G Uphill course. If this course has not been completed, the following prerequisite test 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 open root groove welds on 6-inch schedule 80 carbon steel pipe in the 5G and 6G positions using E7010 electrodes. This course also develops skills for Welder, Arc (DOT 810.384-014).
Course content: This course provides the student with a thorough understanding of downhill pipe welding procedures and weld quality. It provides training to develop the skills necessary to produce quality welds on open root carbon steel pipe in the 5G and 6G positions, using E7010 electrodes.
Testing: To pass this course, the student is required to take two written tests. The student also must pass a visual test on 6-inch diameter schedule 80 pipe in the 5G position, and must pass a visual guided bend and nick break test in the 6G position.
