Abstract:

To provide a laser arc welding equipment and method and a method of laser arc coating with which equipment and method a weld zone having a constant quality regardless of a worker's skill is available and an automization is possible.

A reflection mirror 13 is housed at the upper part and a condenser lens 14 is housed at the lower part of a welding torch 4A. A window 12 is provided on the side face at the upper part of the welding torch 4A, a laser beam 11 emitted from a laser beam head 10 is transmitted into the inside of the welding torch 4A through the window 12, and the laser beam is reflected on the reflection mirror 13 and deflected at right angle and converged by a condenser lens 14. The laser beam converged by the condenser lens 14 is radiated upon the tip of a welding wire 1 to melt the welding wire 1 and a laser plasma 9 is generated. Meanwhile, an arc plasma 9 generated by applying a voltage given by an arc power supply 6 between the welding wire 1 and a base material 5A is introduced to the base material, and the groove of the base material is melted.
