Laser welding method and device

Abstract

The invention discloses a laser welding method and device. The method comprises the steps that a controller obtains position information and welding direction information of a plurality of to-be-welded weld beads on a to-be-welded workpiece; the controller obtains associated welding parameters used for being associated with the multiple to-be-welded weld beads respectively, wherein the multiple associated welding parameters at least comprise one or more of laser power parameters and wire filling parameters; the controller associates the associated welding parameters with the to-be-welded welding beads corresponding to the associated welding parameters, so that each to-be-welded welding bead is associated with the corresponding associated welding parameter; and the controller controls a laser welding hand to perform laser welding on the multiple to-be-welded welding beads in sequence according to the position information, the welding direction information and the associated welding parameters of the multiple to-be-welded welding beads. The laser welding method and device can adapt to complex to-be-welded products and various different types of welding beads, and the intelligent performance of a welding machine is greatly improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a laser welding method and device. Background technique [0002] Laser welding machine has high welding efficiency, good welding quality, good economy, high degree of automation, can perform complex angle welding, small welding deformation, small spatter, and is widely used in industrial welding. [0003] The existing laser welding machine, in the welding process, generally sets the welding parameters for the entire welding process before welding, and is used to output or move according to the set parameters when welding the weld; but in actual laser welding, Due to the complexity of the product to be welded, there are usually multiple different types of weld beads. Different welding methods are required for different types of weld beads, and even different weld positions on complex weld beads. However, existing laser welding robots Often the configuration parameters are integr...

[0003] The existing laser welding machine, in the welding process, generally sets the welding parameters for the entire welding process before welding, and is used to output or move according to the set parameters when welding the weld; but in actual laser welding, Due to the complexity of the product to be welded, there are usually multiple different types of weld beads. Different welding methods are required for different types of weld beads, and even different weld positions on complex weld beads. However, existing laser welding robots Often the configuration parameters are integrated, and the automatic welding requirements of different positions of the same product cannot be realized
