In the processing of industrial equipment, the welding operation of thin-walled materials such as low-carbon steel, aluminum, copper, titanium alloys, and precision parts is a very important step. Laser welding equipment uses continuous automatic laser welding as a relatively advanced welding Technology is replacing more and more traditional welding operations.
Let’s first understand what are the advantages of laser welding? The laser welding heat source is concentrated, the heat input is small, and the pulse rise time of the fiber laser and the characteristics of high beam quality, so the density of the welding material can be more concentrated, the laser wavelength is relatively shorter, and the problem of high reflection is improved. Therefore, laser welding is especially Suitable for metal welding.
Laser welding In a given optical system, the higher the output beam quality, the smaller the size of the laser spot, so the working efficiency of the welding equipment can be improved. At present, laser welding mainly adopts conventional methods such as TIG welding and MIG welding. Regardless of the welding method, relevant preparations before welding must be done in advance, otherwise the welding quality of aluminum alloys will be greatly affected.
What are the preparations before welding? First of all, it is necessary to wipe with absolute alcohol or acetone to remove impurities such as water or oil adsorbed on the surface of the material. Secondly, the workpiece needs to be mechanically polished or chemically treated and dried to complete the welding as soon as possible to prevent the workpiece from being oxidized. In order to improve the weld forming effect, add a copper pad on the back of the aluminum alloy bow and arrow welding to speed up the fluidity of the molten pool during aluminum alloy welding; when welding, use Ar gas protection to isolate the air and reduce the generation of pores. Only when these preparations are done well can the welding effect be guaranteed!
As a new way of welding, laser welding equipment is widely used in a variety of industries, our long-term supply of a large number of models of laser welding machine equipment, and provide laser welding technology solutions, one-stop service, welcome to consult and understand!
