Problems solved by technology

Taking the single laser welding technology as an example, it is generally necessary to add processes such as plate cleaning and plate preheating before welding plates using single laser welding technology. There are problems such as undercutting, poor weld formation, and easy generation of air bubbles at the weld
Taking the single laser cladding technology as an example, the plate after the single laser cladding treatment has problems such as more porosity, coarse grains, uneven powder melting, and uneven cladding surface.

Abstract

The invention discloses a composite laser processing method and a composite laser processing device. The method comprises the steps that N laser beams are composited in a non-coaxial manner to obtain composite laser, each laser beam in the N laser beams corresponds to one processing procedure, the composite laser forms N light spots on a to-be-processed target, the N light spots are linearly arranged in the processing direction, and a preset distance is formed between every two adjacent light spots, so that N processing procedures are sequentially implemented on one or more positions on the to-be-processed target, wherein N is a positive integer greater than or equal to 2. The method can be used for compositing the N laser beams with any wavelength and any processing characteristic, and the method has the advantage of simplifying the processing procedures. The composite laser processing device disclosed by the embodiment of the invention can be used for processing by adopting the method, and has the advantages of being reasonable in overall structural layout and suitable for industrial production requirements.

Description

technical field [0001] The present application relates to the technical field of laser processing, in particular to a composite laser processing method and a composite laser processing device. Background technique [0002] Laser processing belongs to non-contact processing, which uses the energy of light to form a spot with high energy density on the target to be processed after being focused by the lens, and relies on the photothermal effect of the spot to perform such processes as cutting, surface treatment, welding, marking and Processing operations such as drilling, where surface treatment includes processing operations such as laser cladding, laser surface alloying, laser phase transformation hardening, and laser surface fusion. Laser processing is especially suitable for processing materials with high hardness, high brittleness and high melting point. [0003] At present, a single laser beam is usually used for laser processing. Although the development of single lase...
