Other AbstractThe invention relates to a technology of laser welding, discloses a liquid-cooled laser welding method and a device. The method comprises the following steps: mixing pressure mixed solution of gas and liquid, forming a liquid curtain to be around the laser. The device comprises laser beams, a focusing lens and a pressure water cavity, wherein the left side of the pressure water cavity is provided with a water inlet, the upper end of the pressure water cavity is provided with a quartz window and an observation window, the lower end of the pressure water cavity is provided with a pressure nozzle, and the laser beams are led in from the upper part of the focusing lens, and passes through the focusing lens and the quartz window arranged on the upper part of the pressure water cavity to enter, and then penetrates through a thin liquid layer in the pressure water cavity to be focused to enter the center of an external processing optical path, high-pressure liquid enters from the water inlet on the left side of the pressure water cavity, and is jetted out through the pressure nozzle to form the liquid curtain around the laser. The invention has the advantages that: 1. thermal deformation of a workpiece is greatly reduced; 2. hurt to the human body is reduced, and the laser processing area is clean and has no scraps: and 3. the work is table, reliable, the structure is simple, the processing and manufacturing are convenient, and the economic benefit is obvious.
