Title:
レーザ溶接システム及びレーザ溶接制御方法
Document Type and Number:
Japanese Patent JP7435543
Kind Code:
B2
Abstract:
A laser welding system includes: a laser irradiation unit (101) configured to irradiate an object to be welded with a laser beam (LB); a temperature distribution measurement unit (103) configured to measure a temperature distribution of a molten pool (MP) formed in the object to be welded by the irradiation of the laser beam (LB); a convection analysis unit (104) configured to analyze a state of convection of the molten pool (MP) based on the temperature distribution of the molten pool (MP) measured by the temperature distribution measurement unit (103); and a laser control unit (107) configured to control an irradiation condition of the laser beam (LB). When the state of convection of the molten pool (MP) analyzed by the convection analysis unit (104) corresponds to a predetermined spatter generation mode, the laser control unit (107) changes the irradiation condition of the laser beam (LB) so that the state of convection of the molten pool (MP) is not in the spatter generation mode.
