PURPOSE:To prevent the generation of a welding flaw and to execute stable welding by bringing a side nozzle for blowing out shield gas, to position control by an NC at the time of projecting a laser beam converged to a condenser lens from a laser processing device, to a work. CONSTITUTION:At the time of converging a laser beam 1 emitted from a laser processing device, to a machining lens 2a and machining it, a side nozzle 3 for blowing out shield gas is brought to position control by an NC 8. By driving motor 9 and executing the angle turning required for a rotary ring 10, the position control is executed. In such a way, even if a welding line is curved complicatedly, no welding flaw is generated and a stable welding work can be executed. |
