Abstract

The invention discloses a laser welding method capable of reducing welding burst points, and belongs to the technical field of laser welding. The welding method comprises the two steps of cleaning andwelding, and a to-be-welded position of a workpiece is welded at the preset output power during cleaning. The laser power density corresponding to the preset output power is smaller than a welding threshold value of the workpiece, the preset output power has a certain amplitude in the cleaning process, and stains can be effectively evaporated before the workpiece is normally welded. The purposesof cleaning the stains and welding the workpiece can be achieved at the same time only through one-time welding, so that welding burst points are reduced, the welding operation efficiency and the welding operation success rate are greatly improved, and the welding cost is reduced.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a laser welding method capable of reducing welding explosion points. Background technique [0002] Laser welding technology belongs to fusion welding, which uses laser beam as the energy source to make it impact on the joint of the weldment to achieve the purpose of welding. Compared with other traditional welding methods, the focused laser beam has a high power density, which can achieve a large aspect ratio and fast welding speed. The laser heating range is small, the welding heat-affected zone is small, and the welding stress and deformation are small. It belongs to non-contact welding, does not need to use electrodes, and has no electrode pollution and loss. In addition, laser welding does not require a vacuum environment, and can realize remote control and automatic production. [0003] Due to the high energy density of laser welding, some defects will also occur du...
