Zusammenfassung:PURPOSE:To position a member to be welded of a stub tube, etc., onto a specific position and tack-weld plural places simultaneously. CONSTITUTION:One side welding torch 14 among welding torches more than two is moved with a means 15 moving toward the other torch 14, a base material 6 is pressed at a specific position with a pressing mean 11 by gripping the member to be welded between torches 14, this device detects the position of the member to be welded 4, and corrects the position of the member to be welded 4 based on the detecting signal and tack-welds it onto the base material 6. In such a way, the device can easily and automatically tack-weld the member to be welded with preventing the welding stress in a short time.
