Air Liquide has designed Laser Nozzle Control, a patented gas nozzle that increases the keyhole opening for linear laser welding. It improves the evacuation of zinc vapors for galvanized steel welding whatever the laser source.
Laser Nozzle Control improves shielding gas distribution, reducing defaults in linear steel welding. It is especially efficient in welding zinc-coated steel sheets in an overlap configuration, such as automotive body manufacturers.
