Improved scarfing nozzles. |
摘要 |
<p>Apparatus for scarfing defects in a metal work-piece has an oxygen discharge nozzle (15) terminating in a nozzle discharge orifice (20) adapted to discharge a sheet-like stream of cutting oxygen of uniform intensity across the surface of a metal workpiece and means (26, 28) for admixing a gas with the oxygen to be discharged through the discharge orifice (20) wherein at least one edge of the sheet-like stream of oxygen is of reduced purity insufficient to scarf a workpiece, while the remainder of the sheet-like stream is sufficient to scarf defects from a workpiece surface.</p> |
