Scarfing nozzle

摘要

Apparatus for scarfing defects in a metal workpiece having an oxygen discharge nozzle terminating in a nozzle discharge orifice adapted to discharge a sheet-like stream of cutting oxygen of uniform intensity across the surface of a metal workpiece and means for admixing a gas with the oxygen to be discharged through the discharge orifice wherein at least one edge of the sheet-like stream of oxygen is of reduced privity insufficient to scarf a workpiece, while the remainder of the sheet-like stream is sufficient to scarf defects from a workpiece surface.
