Japanese Patent JP2023012241
Kind Code:
A
Abstract:
To provide a welding device which can control heat gain to a base material more precisely by using laser-arc hybrid welding method.SOLUTION: A welding device welds a base material by using laser welding and arc welding. The welding device includes: an arc welding torch which generates an arc between itself and a joint part of the base material; a laser welding torch which radiates a laser to the joint part; a measuring part which measures a state of the laser welding using the laser welding torch; and a control unit which controls arc welding using the arc welding torch based on a measurement result of the measuring part.SELECTED DRAWING: Figure 1
