PURPOSE:To efficiently remove the defective part generated on the inner surface of bellows at narrow parts with the repair welding in the repair welding equipment for bellows. CONSTITUTION:This equipment is provided with a moving frame to be inserted into a ring like clearance, a laser torch 5a outputting a laser beam, a mirror supporting arm 5b arranged freely oscillatably, a fixed mirror 5c reflecting the laser beam, an arm oscillating means oscillating the mirror supporting arm, a head oscillating mirror 5e radiating the laser beam to the weld part y to be repaired, and a mirror angle setting means 5f setting the irradiation position of the laser beam. The defective part, etc., is removed by irradiating the weld part to be repaired with the laser beam and making the defective part, etc., in a molten state. |
