Embodiment Construction
[0011] Such as figure 1 , figure 2 As shown, the present invention is a process for laser welding pipe and plate seams, the welding surface of the pipes and plates to be welded is processed into an inclined surface, and the welded joints can be matched and assembled together, and then the welding head is tilted. welding.
[0012] Process the lower end of the welded joint into a V-shaped groove. And this V-shaped groove is only needed when necessary, for example, when the weld seam is very thick, and the base metal is not thick and can be penetrated at one time, this groove can be omitted.
[0013] After the welding head is set obliquely, its axial direction coincides with the surface where the splicing seam is located.
[0014] In the present invention, the welding head is arranged under the welding seam, and the inclination direction of the welding head and the seam is consistent, so that welding impurities can fall naturally, and the inclined seam can better prevent weld...
