Title:
LASER ARC HYBRID WELDING APPARATUS
Document Type and Number:
Japanese Patent JP2023173547
Kind Code:
A
Abstract:
To provide a laser arc hybrid welding apparatus capable of efficiently preheating a weld wire and suppressing complication of a construction of the apparatus.SOLUTION: A laser arc hybrid welding apparatus 1 includes: a welding torch 10 for welding a parent material 2 by generating arch 25 between the parent material 2 and a weld wire 20; and a laser torch 40 radiating a first laser 51 toward an area separated in a travelling direction of welding rather than an area in which the welding torch 10 generates the arc 25 in the parent material 2, and radiating a second laser 52 toward the weld wire 20. An area to which the first laser 51 is radiated by the laser torch 40 is welded by the welding torch 10.SELECTED DRAWING: Figure 1
