Example Embodiment

[0011] like figure 1 , figure 2 As shown, the process of laser welding pipe and sheet seam of the present invention will require welding pipes and sheet welding surfaces to be inclined, and the mating of the welded splicing can be colled together, and then tilted the solder joint welding.

[0012] Process the welded splicing to a V-slope port. And this V-shaped slope is only required, for example, the weld is very thick, the base material is not thick, and it can be used once, and may not be this groove.

[0013] The axial direction and the splicing seam are gradually incorporated after the tilt setting of the weld joint.

[0014] The present invention places the welded joint under the welding splicing joint, and the welding joint is consistent with the tilt direction of the splicing seam, so that the weld impurity can naturally drop, the tilt setting of the stitching seam is better to avoid welding impurities and splash. On the weld head, and the V-shaped slope port is provided a...

Abstract

The invention provides a process for laser welding of of joints of pipelines and plates in order to overcome the defects in the prior art. Welding impurities and splashes are prevented from falling into a welding head to damage the welding head. In order to solve the technical problem, the technical scheme adopted by the invention is as follows: according to the process for laser welding of the joints of the pipelines and the plates, the welding surfaces of the pipelines and the plates which need to be welded are machined into inclined surfaces, the welded splicing positions can be spliced together in a matched manner, and then the welding head is inclined for welding; and when a welding material is too thick, the lower ends of the welded splicing positions are machined into V-shaped grooves, and after the welding head is obliquely arranged, the axial direction of the welding head coincides with the faces where the splicing joints are located.

Description

technical field [0001] The invention relates to a process for laser welding pipes and plate joints, which belongs to the technical field of laser welding. Background technique [0002] In the existing laser welding process, when the welding environment requires, the welding head must be below the weld seam and weld upward, such as field pipeline welding, the oil pipeline is fixed and cannot be rotated, and the laser head needs to rotate around the pipeline and weld. When the laser head turns to the bottom of the pipe and welds upward, welding spatter and residues will easily fall into the inside of the welding head, polluting the inside of the laser head, and then easily refracting the laser inside the laser head, causing the laser head to burn out. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art, provides a process for laser welding pipes and plate joints, and prevents welding impurities and spatter from falling into the weldin...
