| 摘要 |
This invention relates to a device for welding a flange (3) of a part (1) having a shaft (2) and the flange (3) to a steel plate (44). The device comprises a supporting shaft (26), on the end of which a hole (37) for receiving the shaft (2) of the part (1) is formed, a supporting member (27) fitted on the axis of the supporting shaft (26) in a rotary manner, a supporting pipe (33) fitted into the supporting member (27) and having a electrode wire (36) inside, and driving mechanisms (40, 41, 42). In this device, the electrode wire (36) is directed so as to face the flange (3) of the part (1), whose shaft (2) has been received in the receiving hole (37). To achieve this arrangement, the head (34) of the tip of the supporting pipe (33) is positioned near the opening of the receiving hole (37) on the end of the supporting shaft (26), wherein the tip of the electrode wire (36) moves around the flange (3) as the supporting member (27) rotates.
