Application of laser welding in powder metallurgy parts.

Due to the powder metallurgical raw materials of special properties and manufacturing process. In some areas are widely used and gradually replaced the traditional metallurgical materials, and now we consider the most is connection between the powder metallurgy parts and other parts. In the 1980s before we apply the most extensive is brazing and projection welding, but the combination of degree is not high, adapt to the high temperature high strength of occasions, so powder metallurgy parts due to the problem of welding eat cold shoulder in many industries.

With the development of technology, in the beginning of the end of 80 in the field of powder metallurgy parts welding have new laser welding join, many advantages of suddenly, also acts as a foil to the US powder metallurgy advantages. Laser welding and traditional welding methods are: depth to width ratio and narrow weld and weld with high strength, small heat affected zone, welding deformation small, effective improve the productivity also realize the welding process automation, and many other advantages.

Now technology is so advanced, each industry has a breakthrough in the field, laser welding and cutting effectively solves the problems we powder metallurgy parts and other parts are connected, I believe that in the near future, we powder metallurgy parts welding project will enter a new breakthrough in the field.
