Advantages and requirements of laser plastic welding

The most important advantage of laser Welding Wire is the ability to very high energy the focal point, the laser beam hit the edge of the two parts to be welded, the input energy to heat them to melt metal. The role of the laser beam after the melting of the material will cool rapidly. In this process, there is a small number will enter in the welded parts. Reduce the thermal deformation in welding, but also reduce the input of thermal energy. Reduce the heat of deformation, and increase the accuracy of the correction, you can save a lot of money and time. Laser Plastic Welding
However, how to improve the welding speed and reduce the low energy input is the challenge. Reduced by heating in the region of low energy input despite its benefits: pearlite, martensite and austenite steel joint structure of the complex type does not change the structure of large-scale, this feature also applies to other steels, such as good carbon deposition is limited to the IF steel; but on the other hand there are some inadequacies, a small amount of energy will lead to a rapid cooling, thermal energy will be imported into the cooling area. Laser Plastic
To reduce the hardening of joints, carefully adjusting the speed of welding parameters, laser power, cooling rate and the focus position is very important. And in order to prevent further hardening of the metal, need to be protected by protective gas such as argon and helium in the material will not be any hot reaction gases.Flux Cored Welding Wire
Small laser beam spot size is another problem caused by cutting-edge quality, and if the middle of the two parts to be welded seams, laser beam through the material to ensure no contact with them to their melts. To avoid this, the requirement for very high precision parts. Currently, field of use is more common to connect two parts of the long slit, which the body can be more and more space in the discovery.
