PURPOSE:To prevent the remaining of excess metals by performing th cutting of welding burr after coinciding with the weld line and center line of a cutting tool by moving the member to be welded after completion of the welding of the member to be welded. CONSTITUTION:The movement of a movable frame 7 is operated so that the weld line is coincided with the center line of cutting tools 52, 53 and this result is inputted into a control circuit. The movable frame 7 is moved by ascending a fixed clamper 10 with its pressure reduction by controlling the solenoid value of the fluid cylinder 14, 17 which drive the clamper 10 and mobile frame 7. This movement is detected by the potentio meter 20 linked to the frame 7, fed back to the control circuit by the movement detecting circuit, the weld line of the members 1, 2 to be welded and the center line of the cutting tools 52, 53 are coincided with comparing the control quantity with the target value and the descent and pressure of the fixed clamper 10 are performed. Thereafter, the welding burr is cut with the tool holder 51, 51 gripping the cutting tool 52, 53 which await at the external part approaching between the fixed frame 6 and mobile frame 7 along guide rails 18, 19.
