<p>PROBLEM TO BE SOLVED: To shorten a time required for welding a whole work in stitch welding. SOLUTION: In laser welding equipment which is provided with a machining head 3 to irradiate a machining pint P on a weld line of a work 1 with a laser beam B and a roller 4 to move rotatively along the weld line together with the machining head while pressing a section near the machining point of the work, the machining head is fixed to a head main body 8, the roller is rotatably supported to a roller support member 10, a moving body 11 advancing/retracting in the direction deviated at a prescribed angle for the weld line is supported to the head main body. A rotation shaft 14 having a center axis C2 extending in the pressing direction of the roller to the work is rotatably arranged to the moving body, the roller support material is fixed to the rotation shaft on the plane orthogonal to the center axis of the rotation shaft at the arrangement so that the center axis C1 is positioned at the position not crossing the center axis of the rotation shaft, a roller return means 15, which energizes the roller at the state apart from the work toward a prescribed neutral position, is arranged.</p> |
