This paper introduces the process of coated vanadium carbide with powder method in place of coated metal vanadium carbide with salt bath treatment. The experimental results are given here.

This paper designs a new kind of nozzle used for laser welding of zinc-coated steels with metal powder and studies the better modality of shielding gas and the powder beam with schlieren device.

It can also be used for any painted, powder coated or polished metal product where a high quality homogeneous finish is required.
