Upon completion of this course, the student should be able to perform bridge code welds and other related structural work, as well as preparation for pipe welding.
Prerequisites: The student must have successfully passed the Hobart Institute of Welding Technology Shielded Metal Arc Welding course. If the student has not completed the above course, skill must be demonstrated by successfully completing the following tests:
- Pass a visual and AWS break test on a fillet weld in the horizontal and overhead position (E6010);
- Pass a visual and AWS guided bend test on a square groove weld in the vertical and horizontal positions (E6011 and E7018)
- and pass a written test.
Prerequisite Testing charge is $100.00.
Course objective: To produce quality multi-pass groove welds with backing in all positions using E7018 electrodes on 1” mild steel in the horizontal, vertical, and overhead positions. To produce quality, multi-pass open root groove welds in all positions using E6010 and E7018 electrodes on 3/8” mild steel plates. The quality of welds is in accordance with the various recognized welding codes. This course also develops skills for Welder, Arc (DOT 810.384-014).
Course content: This course provides training to develop skills necessary to produce quality multi-pass groove welds with backing on 1” plate in the horizontal, vertical, and overhead positions; and to produce quality open root single V-groove welds on 3/8” mild steel plate in horizontal, vertical, and overhead positions. Welding related information is also provided on hard surfacing, repair of cast iron and metal identification. In addition, welding related information is included about procedure and welder qualification on destructive and nondestructive testing methods.
Testing: To pass this course, the student is required to take four written tests. The student also must pass visual and guided bend tests on single V-groove welds with backing on 1” mild steel plates in the vertical and overhead positions. Tests are also given on single V-groove welds on 3/8” mild steel plates in the horizontal, vertical and overhead positions.
