PCT No. PCT/DE92/00295 Sec. 371 Date Sep. 24, 1993 Sec. 102(e) Date Sep. 24, 1993 PCT Filed Apr. 7, 1992 PCT Pub. No. WO92/18653 PCT Pub. Date Oct. 29, 1992.A process for remelting metal surfaces, in particular, camshafts, using a laser. The invention shortens the cycle times and further increases cost-effectiveness by not requiring remelting in a plurality of steps. The process uses a laser beam which is focused to a rectangle. The length of the beam spot extends over the entire width of the workpiece surface of the cam. The power density and relative speed are set in order to achieve the desired remelting depth.
