GAS SHIELDED ARC WELDING APPARATUS

摘要

A gas shielded arc welding apparatus (S), in which the positions of torches can easily be adjusted, comprises: electrode torches (10, 20) having electrodes; a filler wire torch (30) for holding filler wire (31); torch clamps (45) for individually holding the electrode torches (10, 20) and the filler wire torch (30); a base (50) on which the torch clamps (45) are supported; and a moving device (100) for moving the base (50). The welding apparatus (S) further comprises: angle adjusting mechanisms (44) with which the set angles of the electrode torches (10, 20) and the filler wire torch (30) are individually adjusted by rotating the electrode torches (10, 20) and the filler wire torch (30) to predetermined angles; and position adjusting mechanisms (60) with which the positions of the electrode torches (10, 20) and the filler wire torch (30) are individually adjusted by moving the electrode torches (10, 20) and the filler wire torch (30) in any direction.
