Problems solved by technology

[0004] However, the scheme of "spraying atomized cooling water" is often not easy to control in actual use, so it cannot effectively improve the deformation effect of thin plate samples after laser welding

Abstract

The invention provides a method for inhibiting laser welding deformation, which comprises the step of using a device for inhibiting laser welding deformation. The device comprises a laser welding headfor welding, a sample clamp used for clamping a sample to be welded, a moving structure, a heat sink structure used for cooling a weld joint subjected to laser welding, and an ultrasonic vibration structure used for making contact with the surface of the sample to be welded. The method is characterized in that in the welding process, the moving structure bears the sample clamp and the sample to move, and the laser welding head, the heat sink structure and the ultrasonic vibration structure are all fixed; or the moving structure bears the laser welding head, the heat sink structure and the ultrasonic vibration structure to move, and the sample clamp and the sample are fixed. The method for inhibiting laser welding deformation provided by the invention can effectively inhibit the deformation of the laser welding sample.

Description

technical field [0001] The invention belongs to the field of laser welding, and in particular relates to a method for suppressing laser welding deformation. Background technique [0002] Laser welding technology is widely used in industrial manufacturing for the connection of specimens. After conventional laser welding and sample cooling, thin-plate specimens will generate residual stress. After the clamp is released, the residual stress is redistributed. Under stress, the sample deforms, which seriously affects the quality of the weldment. [0003] Patent application CN200510105424.5 relates to a laser welding method and device using medium cooling for controlling welding stress and deformation in the manufacture of welded structures. After the laser welding head, there is a heat sink that moves synchronously. The heat sink is composed of a cooling medium pipe, a high-pressure air intake pipe, and an exhaust pipe. The cooling medium pipe at the outlet of the heat sink n...
