Embodiment

[0043] The inventor found that the existing welding technology focuses all the energy on a very small point. In the actual seam welding welding production, because under the same welding pool effect conditions, the molten pool area on the product butt joint determines the welding capacity. Therefore, in the actual production operation, the movement trajectory of the laser focus and the overlapping precision of the product joint seam require high accuracy, which increases the difficulty of welding , and it is difficult to guarantee the welding quality.

[0044] Based on this, the present embodiment provides a laser welding process, which uses the laser beam 20 to pass through the lens assembly 10 of the welding lens, which can improve the welding quality.

[0045] Specifically, please refer to figure 1 , using the laser beam 20 to pass through the lens assembly 10 in the laser welding lens to form a molten pool on the weldment with two focused spots formed in a preset directio...

Abstract

The invention provides a laser welding technology, and belongs to the technical field of laser welding. The laser welding technology comprises the steps that a molten pool is formed on a weldment by utilizing two focusing spots formed in the preset direction through a laser light beam penetrating through a lens assembly in a laser welding lens, the two focusing spots comprise the first focusing spot and the second focusing spot, the first focusing spot and the second focusing spot are linear spots or elliptical spots, the projections of the first focusing spot and the second focusing spot in the preset direction have preset angles, and the length of the molten pool is greater than the width of the molten pool. The welding technology has the good welding effect.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a laser welding process. Background technique [0002] Laser welding is a combination of modern technology and traditional technology. Compared with traditional welding technology, laser welding can greatly improve the efficiency and precision of welding with its unique features. Laser welding technology belongs to fusion welding, which uses laser beam as the energy source to make it impact on the joint of the weldment to achieve the purpose of welding. [0003] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction, that is, the laser radiation heats the surface of the workpiece...
