Laser welding is the use of high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation is directed to the internal diffusion of the material through heat transfer, and the material is melted to form a specific molten pool. Laser welding machine is also often called laser welding machine, energy negative feedback laser welding machine, laser welding machine, laser welding machine, laser cold welding machine, laser argon welding machine, laser welding equipment, etc.
Laser welding is a new type of welding method, which mainly aims at the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, overlap welding, seal welding, etc. with high depth width ratio, small weld width, small heat affected zone, small deformation, fast welding speed, flat and beautiful weld, no treatment or simple treatment after welding, high weld quality, no pores, and can be accurately controlled, Small focusing light spot, high positioning accuracy and easy to realize automation.
Stainless steel products are more and more widely used in our daily life, such as sink, thermos cup, doors and windows, kitchen and bathroom, office Kitchenware and so on. So, what are the advantages of laser welding stainless steel compared with traditional stainless steel welding?
Advantages of laser welding machine welding stainless steel
1. Laser welding machine has the advantages of fast welding speed, large depth and small deformation; Little heat is generated in the welding process, which can avoid the thermal deformation of the weld area; The welding surface is neat, the weld quality is high, the overall appearance is beautiful, and there are no pores. There is no need to polish the welding without excessive requirements.
2. Laser welding 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 effect. After laser focusing, the power density is high. When welding high-power devices, the depth width ratio can reach 5:1 and up to 10:1.
3. Laser welding can be used for micro welding. After focusing the laser beam, a small spot can be obtained and can be positioned accurately. It can be applied to the assembly and welding of micro and small workpieces produced in large quantities; It can weld inaccessible parts, and implement non-contact long-distance welding, which has great flexibility. The laser beam is easy to realize the beam splitting according to time and space, and can carry out multi beam simultaneous processing and multi station processing, which provides conditions for more precise welding.
