摘要： 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.

摘要： The method comprises the steps of: a) supplying building material; and b) fusing the building material using a light beam (2); wherein steps a) and b) are carried out so as to progressively produce the object out of the fused building material. In step b), the beam (2) is projected onto the building material so as to produce a primary spot on the building material, the beam being repetitively scanned in two dimensions in accordance with a first scanning pattern so as to establish an effective spot (21) on the building material, said effective spot having a two-dimensional energy distribution. The effective spot (21) is displaced in relation to the object being produced to progressively produce the object by fusing the building material.

摘要： 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 scanning pattern can comprises at least three substantially parallel lines which the laser spot follow in a certain order. When the workpiece comprises several journals having different widths, two laser sources (1, 1A) may be used to harden the surface area of the wider journals.
