<p>PROBLEM TO BE SOLVED: To enable combination with a robot with low positioning accuracy, and adjust the position by a simple method so as to carry out laser welding. SOLUTION: A detecting laser from a laser diode 510 is reflected by a polarized prism 512 and radiated at the position separated by L2 from a center axis O of a work 1 via a lens 513 and the like. Then, the laser is reflected by the work 1 and incident on a photo diode 511. An optical axis of a processing laser light from an optical fiber 4 is set at the position separated by L1 from the center axis O of the work 1 in the route via a lens 520 and the like. A motor 55 inside a processing head is rotated for rotating wedge substrates 515, 521 and parallel flat substrates 516, 522. Furthermore, the irradiation position of the detecting laser and the optical axis of the processing laser in the work 1 are revolved around the center axis O as a center for detecting the butt face by the reflection light of the detecting laser. When the optical axis of the processing laser is positioned at the butt face, the processing laser is radiated to the work 1.</p> |
