<p><P>PROBLEM TO BE SOLVED: To provide a laser beam machining apparatus capable of performing efficient execution even when performing the cladding by welding over a relatively wide range. <P>SOLUTION: The laser beam machining apparatus 100 comprises a laser beam oscillation apparatus 110 for oscillating laser beams 1, and a machining head 120 which makes a base material 11 be irradiated with the laser beams 1 from the laser beam oscillation apparatus 110 and can be relatively moved with respect to the base material 11. The machining head 120 has a cylindrical lens 123 for expanding the laser beams 1 in the direction along the base material 11 across the moving direction to the base material 11, and has a weld metal feeder 130 for feeding metal powder 12 to the base material 11 over the irradiation range of the laser beams 1 in the direction along the base material 11 across the moving direction to the base material 11 of the machining head 120. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
