Abstract
PURPOSE:To prevent the temp. rise of reflecting mirrors, and obtain weld zones of stable depth of penetration by providing means of blowing cooling gas to the reflecting mirrors in a laser working device. CONSTITUTION:Laser light 10 is conducted to a spherical reflecting mirror 4e by 4 pieces of plane reflecting mirrors 4a-4d. The laser light reflected by the mirror 4e is condensed and is irradiated to a weld zone 12. At this time, a rotary head rotating part 1 is rotated by a motor 2 and a belt 8, and therefore a pipe 14 is circumferentially welded to a pipe plate 13. At this time, a gas is blown to the reflecting mirrors via a gas supply pipe 5, a gas storage groove 6 provided over the entire circumference of the nonrotating part, gas lead-in ports 9 provided at two places in the rotating part and gas nozzles blowing the gas to the reflecting mirrors, whereby the mirrors are cooled. By this gas cooling, the temp. rise of the reflecting mirrors is reduced, and the weld zone 12 having stable depth of penetration is obtained.
