<p><P>PROBLEM TO BE SOLVED: To provide laser welding equipment that is easily arranged and forms an excellent weld zone. <P>SOLUTION: In the laser welding equipment 4, a filler wire feeding nozzle 6 goes through the inside of an assist gas supply nozzle 5, consequently the periphery of a laser machining head 2 has simpler structure compared with structure where the filler wire feeding nozzle 6 and the assist gas supply nozzle 5 are arranged on both sides of the laser machining head 2 held in-between, so that the equipment is easily arranged when for example a narrow part and a circular arc part are welded. Also, in viewing from the distal end face of the assist gas supply nozzle 5, the assist gas supply nozzle 5 and the filler wire feeding nozzle 6 are coaxial, which suppresses turbulence of the assist gas G passing through the assist gas supply nozzle 5. As a result, an excellent weld zone 7 can be formed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
