Laser welding features
Laser is considered to be the ideal heat source for welding and is recognized as a high technology. Laser welding has heating concentration, less heat input, small deformation, fast welding speed; The weld depth ratio is large, the weld is flat, beautiful, no treatment after welding or only simple treatment, the weld quality is high, no porosity; Precise control, small focus point, high positioning accuracy, easy to achieve automation; It is not only suitable for conventional materials, but also especially suitable for insoluble metals and heat-resistant alloys. The dissimilar metals with large differences in the thermal physical properties of titanium alloy, the workpieces with large differences in volume and thickness and the components near the welds are flammable under heat, easy to crack under heat and explosive under heat. Compared with vacuum electron beam welding, laser welding has the advantages of no X-ray, no vacuum chamber, and no limit on the volume of the workpiece. Laser welding can be used as the final processing, the weld is beautiful and beautiful, and in many cases the weld can be strong with the base material. Laser welding can be spot welding, continuous seam welding, overlap welding, sealing welding, etc., depth to width ratio is high, weld width is small, heat affected zone is small, and deformation is small.
