Upon completion of the course, the student should have developed downhill pipe welding techniques for techniques for the service transmission piping fields.

Prerequisites: The student must have successfully passed the Hobart Institute of Welding Technology Shielded Metal Arc Welding and Shielded Metal Arc Welding Advanced courses. Students in the 38-week Combination Structural & Pipe Welding Program must successfully complete Shielded Metal Arc Welding Pipe courses including 2, 5, and 6G prior to taking downhill. Any other student must pass the Shielded Metal Arc Welding Pipe courses or must pass the downhill prerequisite testing. If the above courses have not been completed, the following prerequisite test is required: Pass a 3/8-inch (9.5) plate open root guided bend test in the vertical down and 45º position – and pass a written test. Prerequisite testing charge is $50.00.

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 6inch diameter schedule 80 pipe in the 5G position, and must pass a visual guided bend and nick break test in the 6G position.
