Laser welding machine is the use of high-energy laser pulses to locally heat a material in a small area. The energy radiated by the laser is directed through heat transfer to the internal diffusion of the material, melting the material and forming a specific molten pool.
Laser welding machine is a new type of welding method, which is mainly aimed at welding thin-walled materials and precision parts. It can realize spot welding, butt welding, overlap welding, seal welding, etc., with high depth to width ratio, small weld width, small Heat-affected zone, small deformation, fast welding speed, smooth and beautiful welds, no treatment or simple treatment after welding, high weld quality, no pores, accurate control, small focus spot, high positioning accuracy, easy to achieve automation.
Stainless steel products are increasingly widely used in our daily lives, such as sinks, insulated cups, doors and windows, kitchen and bathroom, office kitchen utensils, and so on. So, what are the advantages of laser welding stainless steel compared to traditional stainless steel welding?
Analysis of the advantages of laser welding machine in welding stainless steel
1.Laser welding machine has fast welding speed, large depth, and small deformation; During the welding process, minimal heat is generated to avoid thermal deformation in the weld area; The welding surface is neat, the weld quality is high, and the overall appearance is beautiful, without pores. For welding with no high requirements, there is no need for polishing and polishing.
2.Laser welding machine can be carried out at room temperature or under special conditions, and the laser welding equipment is simple; It can weld refractory materials such as titanium, and can weld dissimilar materials with good results. After laser focusing, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1, with a maximum of 10:1.
3.Laser welding machine can perform micro welding. After focusing the laser beam, a very small spot can be obtained and accurately positioned, which can be applied to the assembly welding of micro and small workpieces in large-scale automated production; It can weld difficult to access parts and has great flexibility by implementing non-contact long-distance welding. Laser beams are easy to achieve beam splitting in time and space, allowing for simultaneous processing of multiple beams and multiple workstations, providing conditions for more precise welding.
