Abstract: Welding equipment includes a torch for irradiating a laser beam B, wire feeding means 2 for feeding a filler wire F, and tracking means 3 for controlling the moving tracks of the torch 1 and the wire feeding means 2 so as to make the moving tracks follow a welding line Y. The tracking means 3 has a contactor 30A provided so as to be advanceable/retractable for making contact with a joint object W resiliently. The torch and the wire feeding means 2 are moved so as to follow the welding line Y by touching the contactor 30A of the tracking means 3 resiliently to the joint object W while feeding the filler wire F to a welding portion and irradiating that portion with the laser beam B, thereby joining the joint objects W.
