Laser welding is one of the important components of laser material processing. Laser welding is a high energy beam as a heat source of a kind of precision welding technology, which is mainly through the high energy laser beam heating the surface of the workpiece, heat from the surface of the material to the internal diffusion, through the adjustment of the parameters of the laser pulse, so that the corresponding material melting, forming a specific melt pool.

The principle of laser welding can be divided into heat conduction welding and laser deep penetration welding. Laser welding uses laser energy to combine materials of different materials, different thicknesses or different shapes to meet the needs of material performance in different situations, and can achieve lightweight equipment with the lightest weight, optimal structure and optimal performance.

So, what are the advantages of laser welding machines in the field of thin plate welding?

Analysis of advantages of laser welding machine in the field of thin plate welding:

Stainless steel materials are widely used in the manufacture of various finished products, of which the welding of stainless steel sheets has become an important process in the production and manufacturing process. However, due to the characteristics of sheet stainless steel itself, it has also caused certain difficulties in welding, and has once become a welding problem in the field of sheet stainless steel.

Traditional welding machine processing sheet stainless steel has a big problem, sheet stainless steel due to its small thermal conductivity, only about one-third of the ordinary low carbon steel, the constraint degree is small, so in the welding process once the local heating and cooling effect, will form uneven stress and strain, the longitudinal contraction of the weld on the outer edge of the stainless steel sheet produce a certain pressure, Once the pressure of the traditional welding machine is too large, it will cause the wave deformation of the workpiece, which not only affects the beauty but also affects the quality of the workpiece, in addition, there will be problems of over-burning and burning through.

The emergence of fiber laser welding machine is a good solution to this problem, laser welding is the use of high energy laser pulse to the material in a small area of local heating, laser radiation energy through the heat conduction to the internal diffusion of the material, the material after melting to form a specific melt pool. High welding depth to width ratio, small weld width, small heat affected zone, small deformation, fast welding speed, smooth and beautiful weld, no need to deal with or only simple treatment after welding, high quality weld, no porosity, accurate control, small focusing spot, high positioning accuracy, easy to achieve automation. Laser welding machines with a number of advantages are gradually replacing the traditional sheet welding market.

The above is the advantages of laser welding machine in the field of thin plate welding analysis. Laser welding machine is widely used in dental denture processing, circuit board welding, splicing plate welding, sensor welding, battery sealing cover welding and other aspects.
