Abstract

The invention relates to the field of welding, in particular to a self-adaptive laser shock welding method and a self-adaptive laser shock welding device, which are suitable for metal welding and welding seam strengthening. The device comprises a parameter input system, a laser and welding parameter matching database system, a machine motion control system, a welding parameter control system, a laser parameter control system, a welding device, a mechanical motion device, a laser tracking welding servo system, a laser welding comprehensive control system and a workbench. According to the method and the device, weldments are welded while punching, matching parameters are selected through the laser and welding parameter matching database system, process parameters are controlled through a control system, and welding and laser shock strengthening of weldments are completed simultaneously according to the time difference of laser shock and relative positions of welding and laser shock. According to the method and the device, simultaneous performance of welding and laser shock strengthening can be realized, and the time sequences and positions of laser shock and welding can be adjusted, so that laser tracking welding under various different process parameter conditions can be met.

Description

technical field [0001] The invention relates to the field of welding, in particular to a method and device for self-adaptive laser shock welding, which can realize welding and laser shock strengthening of welds at the same time, and the process parameters can be adjusted and controlled, especially suitable for the automation of high-quality welds Welded and strengthened. Background of the invention [0002] For thick plate welded structures, whether it is thermal cracks, crack initiation and propagation caused by residual stress, stress corrosion cracking, or fatigue damage, the reason is due to the existence of tensile stress (mainly reflected in welding residual tensile stress), so the reduction Or the method of eliminating the residual tensile stress of welded joints can improve the crack resistance of welded structures. At present, the methods to improve the fatigue strength and crack resistance of welded joints are roughly divided into subsequent heat treatment and sur...
