What Are The Advantages Of Laser Welding Machine Welding In The Thin Plate Field?

Laser welding is one of the important components of laser material processing. Laser welding is a precision welding technology that uses a high-energy beam as a heat source. It mainly heats the surface of the workpiece through a high-energy laser beam, and the heat diffuses from the surface of the material to the inside. By adjusting the parameters of the laser pulse, the corresponding The material melts to form a specific molten pool.

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

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

Analysis of the 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, and the welding of stainless steel sheets has become an important process in the manufacturing process. However, due to the characteristics of thin-plate stainless steel, welding has certain difficulties, and it has once become a welding problem in the field of thin-plate stainless steel.

There is a big problem in traditional welding and machining of thin-plate stainless steel. Due to its small thermal conductivity, which is only about one-third of that of ordinary low-carbon steel, the degree of constraint is small, so once it is locally heated and cooled during the welding process The role of the welding machine will cause uneven stress and strain. The longitudinal shrinkage of the weld will produce a certain pressure on the outer edge of the stainless steel sheet. In addition to the quality of the workpiece, there will also be problems of over-burning and burn-through.

The emergence of fiber laser welding machine has solved this problem very well. Laser welding is to use high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses into the interior of the material through heat conduction and melts the material. Then a specific molten pool is formed. High welding depth-to-width ratio, small weld width, small heat-affected zone, small deformation, fast welding speed, smooth and beautiful weld seam, no post-weld treatment or only simple treatment, high-quality weld seam, no porosity, and precise control , small focus spot, high positioning accuracy, easy to realize automation. With many advantages, laser welding machines are gradually replacing the traditional sheet welding market.


The above is Laser Delta’s analysis of the advantages of laser welding machines in the field of thin plate welding. Laser welding machines are widely used in dental denture processing, circuit board welding, splicing steel plate welding, sensor welding, battery sealing cover welding, etc.
