What are the advantages of fiber laser welding machine in the thin plate welding field?
Laser welding uses high-energy laser pulses to locally heat a material in a small area. The energy of laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision metal parts. It can realize spot welding, butt welding, stitch welding, sealing welding, etc. Small weld width, and small heat affected zone, small deformation, fast welding speed, smooth and beautiful welding seam, no need to secondary processingafter welding, high positioning accuracy, and easy to realize automation.
So, what are the advantages of fiber laser welding machine in the thin plate welding field?
Stainless steel is the commonly used materials in the industrial field, so stainless steel welding is an important process in the manufacturing. However, due to its own characteristics of thin-plate stainless steel, it is difficult to weld for traditional welding technology
Due to its low thermal conductivity of stainless steel , which is only about one-third of the carbon steel. Therefore, once the welding process is locally heated and cooled, it will Uneven stress and strain are formed. The longitudinal shrinkage of the welding seam creates a certain pressure on the outer edge of the stainless steel sheet. Once the pressure of the traditional welding machine is too large, it will cause wave-like deformation of the workpiece, which not only affects the appearance, but also affects the quality of the workpiece. In addition, there will be over-burning and burn-through.
Fiber Laser welding solves this problem well due to its own technology and working principle. And the welding quality is perfect.
Laser welding machines are widely used in precision workpiece, circuit board, splicing steel plate , sensor, battery sealing cover welding, etc. The welds are beautiful and fine, and they are recognized by customers.
There are handheld fiber welding machine and automatic fiber laser welding machine can be selected, which can be applied to different industries and different materials. If you are interested, please feel free to contact us.
