  • Process for hardening cutting edges with an oval shaped plasma beam
    Patent number: 5360495
    Abstract: An apparatus and process for hardening cutting edges having various widths. The apparatus includes a plasma torch for projecting a plasma beam through an outlet nozzle. The outlet nozzle has a length parallel to the cutting edge and a width perpendicular to the cutting edge. The nozzle width is greater than the nozzle length. A variable electromagnet is located adjacent the nozzle for adjustably deflecting the plasma beam from a circular cross section beam to a widened beam. The electromagnet deflects the plasma beam at its width so that it is slightly wider than the width of the cutting edge to be hardened. The plasma beams with a smaller cross section have a lower power consumption and a constant gas flow rate than larger cross sectional beams.
