It is preferable to irradiate the pulse laser beam oscillation or Q-switch oscillation laser beam with the average output of the laser beam of 50-500 W and the peak output of the laser beam of 200-10 kW. The position of the laser beam irradiation is preferably at a groove bottom part or an inclined surface of the groove within 2 mm from the groove bottom part. The position of the laser beam irradiation is oscillated as necessary, and the cathode of the arc is moved to the irradiation position.
