  • Welding and Inspection Procedures for In-Service WeldingTWI

    Additionally in order to qualify a procedure for in-service welding for all positions API 1104 indicates that a test rig in which the longitudinal axis of the pipe is held at 45° to horizontal should be constructed. This test rig qualifies welding in all positions and when filled with flowing water should generate more severe thermal cooling S ome repairs whether it is repairing a failed weldment or repairing a crack in a casting may easily be done by simply grinding out the crack and applying more weld. Other repairs however are more complicated. Or at least they should be.
