METHOD AND SYSTEM FOR LASER HARDENING OF A SURFACE OF A WORKPIECE
Method of laser hardening of a surface area of a workpiece, such as a surface of a journal of a crankshaft comprising: generating a relative movement between the surface of the workpiece and a laser source to allow a laser spot to subsequently be projected onto different portions of said surface area, and during said relative movement, repetitively scanning the laser beam (2) so as to produce a two-dimensional equivalent effective laser spot (5) on said surface area. The energy distribution of the effective laser spot is adapted so that it is different in a more heat sensitive subarea, such as in an area adjacent to an oil lubrication opening, than in a less heat sensitive subarea, so as to prevent overheating of said more heat sensitive subarea.
