The properties of full thickness repair welding seam that generated by 6 kinds of welding material under the same repair welding condition were comparatively investigated by V-notch Charpy impact toughness test, micro-hardness test and tensile test, and selected out the repair welding material matching with better weld performance. Taking the selected welding material as special welding material for manual repairing the weld defect in φ1 219 mm ×18.4 mm X80M SAWH pipe, the full thickness repair welding tests for the different welding process parameter were conducted, and the low temperature impact test for repair weld was carried out. Finally, it determined the repair welding process for φ1 219 mm×18.4 mm X80M SAWH pipe. The results indicated that the SHJ557 welding electrode produced by Shanghai Welding Equipment Factory is more suitable for the above repair welding process of φ1 219 mm ×18.4 mm X80M SAWH pipe, the various performance indexes are higher; the determined repair welding process parameters are reasonable, it ensures the quality of repair weld and the mass production of steel pipe.
