Embodiment Construction
[0019] The present invention will be further described below in conjunction with accompanying drawing. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0020] The schematic diagram of the technical solution of this embodiment is as attached figure 1 shown. On the basis of the conventional laser welding process, a 5 mm thick SJ301 sintered flux 5 is spread on the bottom of the laser to-be-acted area of the workpiece 4 to be welded. The laser beam 2 is incident from the front of the workpiece 4 to perform laser welding on the workpiece. During the welding process, the laser energy transmitted from the deep melting hole and the heat conduction of the molten pool 3 heat and melt the flux 5, and the molten flux covers the back of the molten pool to form a support for the molten pool and at the same time realize the protection of the back of the weld....
