Embodiment Construction

[0021] Based on the fact that laser welding technology can improve the welding quality between the main pipe and the branch pipe of the metal tee pipe, a laser welding method is proposed, which is suitable for welding between the main pipe and the branch pipe of the metal tee pipe, including the following steps:

[0022] a. Make the main pipe and branch pipe of the metal tee pipe ready for welding and rotate them;

[0023] b. The main pipe and the branch pipe are welded together using a laser welding head that performs linear reciprocating motion relative to the plane of rotation of the main pipe.

[0024] The laser welding method will be specifically described below in combination with specific embodiments. refer to Figure 1 to Figure 3 , the laser welding method specifically also includes the following steps:

[0025] S101 , a step of inserting the branch pipe 404 into a preset hole on the main pipe 402 . The branch pipe 404 is usually perpendicular to the main pipe 402 ...

Abstract

The invention discloses a laser welding method, which is suitable for welding a main tube and a branch tube of a metal three-way tube. The method comprises the following steps of: setting the main tube and the branch tube of the metal three-way tube in a to-be-welded state, and rotating the main tube and the branch tube; and welding the main tube and the branch tube together by using a laser welding head which moves linearly in a reciprocating way relative to the rotating plane of the main tube. In the laser welding method, the metal three-way tube is rotated, and the laser welding head moves in a reciprocating way relative to the metal three-way tube simultaneously, so that the difference compensating welding of the metal three-way tube is realized, lack of weld is prevented, and the welding quality is improved. Moreover, the invention further provides a laser welding device.

Description

【Technical field】 [0001] The invention relates to the technical field of laser processing, in particular to a laser welding method and a laser welding device. 【Background technique】 [0002] The metal tee is usually composed of a main pipe and a branch pipe which is perpendicular to the main pipe and communicates with the main pipe on one side of the main pipe. The main pipe and the branch pipe are welded together. [0003] Traditional metal tee pipes are generally welded by sub-arc welding, and the welding quality is poor. 【Content of invention】 [0004] Based on this, it is necessary to provide a laser welding method and a laser welding device to achieve the purpose of improving the welding quality of the metal tee pipe. [0005] A laser welding method is suitable for welding between the main pipe and the branch pipe of the metal tee pipe, which comprises the following steps: a, making the main pipe and the branch pipe of the metal tee pipe be in a state to be welded an...
