Abstract

The invention provides a laser welding system and method, and belongs to the technical field of laser welding. The laser welding system comprises a sample table, a first laser generation device, a second laser generation device, a first optical shutter and a light adjusting device. The first optical shutter is arranged in a light propagation path between the first laser generation device and a workpiece, a first laser beam sent out of the first laser generation device enters the first optical shutter, and the first laser beam passing through the first optical shutter is focused at the preset position of the workpiece through the light adjusting device. A second laser beam sent out of the second laser generation device is focused on the preset position through the light adjusting device. According to the laser welding system and method, laser welding of materials of copper, an alloy of the copper and the like with high reflectivity and the high heat conduction coefficient is achieved, pre-welding preheating or after-welding slow cooling of the workpiece is achieved, and the welding stress is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of laser welding, in particular to a laser welding system and method. Background technique [0002] Copper and its alloys have excellent electrical conductivity, thermal conductivity, and corrosion resistance, and are widely used in electric power, electrician, and electronic appliances industries. They are mainly used to make electrical equipment such as generators, switchgear, and transformers, heat exchangers, and solar panels. Heat collectors and other heat conducting equipment. The welding of its components is mostly involved in the manufacturing process. [0003] The traditional methods used for copper welding mainly include gas welding, manual arc welding, and argon arc welding. Gas welding, manual arc welding, and argon arc welding all require filler wire welding or flux, and preheating before welding is required to prevent cracks. , the process is complicated; when the workpiece is thicker...
