ABSTRACT:
A hot forged article of a preselected profile is produced by heating a forging blank to elevated temperature and forging the blank at the elevated temperature between closed dies, to produce a forging of about the preselected profile of the final forging, but having flashing thereon. The flashing is removed by cooling the forging having flashing thereon to ambient temperature, and trimming the flashing from the forging by passing a trimming laser beam of sufficient power density to cut through the flashing along the preselected final profile of the forging. The forging may be post treated by passing a post treating excimer laser along the portion of the forging immediately adjacent the preselected profile, after the trimming laser has passed. The post treatment removes the heat affected zone, depending upon the energy level of the excimer laser.
