Abstract

LSM240 fully automatic SLAB laser welding machine is used to weld Fe-based,Ni-based,Co-based powder materials in order to study the important factors for welding quality,i.e.the defocus,welding speed and specific energy.Results show that Ni is the most sensitive to the defocus.The formula of the relation of penetration H and specific energy input W is gotten.
