Document Type and Number:
WIPO Patent Application WO/2017/006704
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a laser welding method with which it is possible to ensure an effective welding length when irradiating a laser beam at an incline. A laser welding method for performing welding by periodically scanning a laser 4 in an oscillating manner and directing the laser 4 on the surface of an object to be welded 9 while the object to be welded 9 is caused to move, wherein at least one of the output, scanning speed, and scanning path of the laser 4 is controlled, and the amount of input heat on both left and right sides along the direction in which welding proceeds is caused to vary substantially, to perform welding.
