ONE-SIDE WELDING MACHINE, PROGRAM USED FOR ONE-SIDE WELDING MACHINE, AND ONE-SIDE WELDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a technique to stabilize the weld quality of a part where a sheet thickness changes in a welding direction.;SOLUTION: An one-side welding machine, which moves a welding torch on one side of steel plates to be welded, and welds the steel plates to be welded together whose end surfaces face to each other, includes: a temporary storage part 14 for storing sheet thickness welding conditions set for each sheet thickness of the welded steel plate to be welded; and a welding condition setting part 12 for, when welding the facing end surfaces of the steel plates to be welded in which the sheet thickness changes in a moving direction of the welding torch, calculating the welding condition of the part where the sheet thickness changes from the sheet thickness welding conditions stored in the temporary storage part, starting read-out of the calculated welding condition based on prescribed read-out instructions, and executing the welding of the part where the sheet thickness changes.;COPYRIGHT: (C)2013,JPO&INPIT
