Abstract

The invention relates to the technical field of welding, in particular to a laser welding method and a device thereof. The laser welding device comprises a laser generating mechanism and a tin feeding mechanism, wherein the tin feeding mechanism comprises a tin feeding needle; the tin feeding needle is a tubular object with an accommodating cavity, and comprises a tube wall which surrounds the accommodating cavity and two end surfaces; and end openings which communicate with the accommodating cavity are separately formed in the two end surfaces; and a notch which communicates with the accommodating cavity is formed in the tube wall, so that a tin wire is fed out from the end openings after being firstly exposed from the notch in a transfer direction. The laser generating mechanism is used for generating laser which acts on the tin wire transferred by the tin feeding needle, so that the tin wire is fed out from the two end openings after being preheated at the notch. The laser welding method adopts the laser welding device to preheat the tin wire, so that a workpiece is welded. The notch which communicates with the accommodating hole is formed in the tube wall, so that the tin wire is fed out from the end openings after being exposed from the notch and being preheated by laser; and the preheated tin wire can be molten more quickly in a welding process, so that welding efficiency is improved.

Description

【Technical field】 [0001] The invention relates to the field of welding technology, in particular to a laser welding method and a device thereof. 【Background technique】 [0002] Laser has the advantages of high energy density and rapid heat conduction, and theoretically can achieve extremely high welding speed. However, in the actual welding process, due to the low utilization rate of the laser and the high energy density of the laser, it is extremely easy to ablate the welding place when heated for a long time. Therefore, to improve the utilization rate of the laser to improve the welding efficiency, it is necessary to melt tin very quickly. Therefore, it is urgent to provide a technical solution to solve the above problems. 【Content of invention】 [0003] In order to overcome the problem of low welding efficiency in the prior art, the present invention provides a laser welding method and a device thereof. [0004] The technical solution of the present invention to solve...
