  • Method and system for laser hardening of a surface of a workplace
    Patent number: 10648056
    Abstract: A method of laser hardening a surface area of a workpiece, such as a surface of a journal of a crankshaft, includes the step of: 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. The method also includes the step of repetitively scanning the laser beam so as to produce a two-dimensional equivalent effective laser spot on said surface area, during the relative movement. The scanning pattern can include at least three substantially parallel lines which the laser spot follows in a certain order. When the workpiece includes several journals having different widths, two laser sources may be used to harden the surface area of the wider journals.
