The laser welding machine is a new processing technology based on the traditional processing technology and modern laser technology. It uses the high-energy laser pulse to locally heat the material in a small area, and diffuses the material through the heat conduction to melt the material. A specific molten pool is formed afterwards. Because laser welding has high power density and fast release energy, it is more efficient in terms of processing efficiency than traditional methods. So, what application areas does laser welding machine technology have?
Electronic product
Laser welding is widely used in the electronics industry, especially in the microelectronics industry. Due to the small heat affected zone of laser welding, rapid heating concentration, and low thermal stress, it is showing unique advantages in the packaging of integrated circuits and semiconductor device casings.
2. Stainless steel products
In general, stainless steel welding is easier to obtain a quality joint than conventional welding. Due to the high welding speed and heat-affected zone of laser welding, the overheating phenomenon of stainless steel welding and the adverse effect of large linear expansion coefficient are alleviated, and the weld has no defects such as porosity and inclusion. Compared to carbon steel, stainless steel is more susceptible to deep-melting narrow welds due to its low thermal conductivity, high energy absorption, and melting efficiency.
3. Plastic material products
Laser welding technology can be used in almost all thermoplastics and thermoplastic elastomers. Commonly used welding materials are PP, PS, PC, ABS, polyamide, PMMA, polyoxymethylene, PET and PBT.
4. Powder metallurgy material products
Laser welding technology has entered the field of powder metallurgy material processing with its unique advantages, opening up new prospects for the application of powder metallurgy materials, such as welding diamonds by the brazing method commonly used in the connection of powder metallurgy materials. Due to the low bonding strength, thermal influence In particular, the width of the zone is not suitable for high temperature and high strength, which causes the solder to melt and fall off. Laser welding can improve the welding strength and high temperature resistance.
