Document Type and Number:
Japanese Patent JP2930914
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To weld the welding zone of a spacer, etc., with a stable welding quality.
SOLUTION: This laser seam welding method is provided with a laser irradiation part 22 which receives a laser beam from a laser generator 21 and emits this laser beam to a weld zone while moving. By regulating the welding area of a welding zone by the laser seam welding method, and also controlling the laser beam output, moving speed, focal distance, etc., in the middle of the welding area, high-quality welding is enabled.
