Laser welding machine industry information
Laser welding machine is a machine used for laser welding in material processing
working principle
Laser welding is the use of high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses into the interior of 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 aimed at the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, lap welding, sealing welding, etc., with high depth-to-width ratio, small weld width, and small heat-affected zone. Small deformation, fast welding speed, flat and beautiful weld seam, no need for post-welding treatment or only simple treatment, high quality weld seam, no porosity, precise control, small focus spot, high positioning accuracy, easy to realize automation
Laser Welding Machine Main Feature Information
The laser welding machine has a high degree of automation and the welding process is simple.
The non-contact operation method can meet the requirements of cleanliness and environmental protection. The use of laser welding to process workpieces can improve work efficiency, and the finished workpiece has beautiful appearance, small weld seam, large welding depth and high welding quality.
Laser welding machines are widely used in dental denture processing, keyboard welding, silicon steel sheet welding, sensor welding, battery sealing cover welding and so on.
However, the cost of the laser welding machine is relatively high, and the precision requirements for the assembly of the workpiece are also relatively high, and there are still limitations in these aspects.

Power
Power is one of the most critical parameters in laser processing. With higher power, the surface layer can be heated to the boiling point within microseconds, resulting in a large amount of vaporization. Therefore, high power is beneficial for material removal processes such as drilling, cutting, and engraving. For lower power, it takes several milliseconds for the surface temperature to reach the boiling point. Before the surface layer vaporizes, the bottom layer reaches the melting point, which is easy to form a good fusion welding
