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.
New construction method is adopted in aspects of ruling, alignment, measurement and welding so that construction quality of oil slurry nozzle can assured.
