  • VOLUME HEAT TREATMENT METHOD AND RELATED SYSTEM
    Publication number: 20230078751
    Abstract: A method for volume heat treating a part having an external surface delimiting its volume, the method comprising the following steps: a. providing a laser source; b. providing the part; c. providing support means for supporting the part; d. placing said part so that it is held in position by said support means; and e. irradiating with the laser source at least one segment of the external surface of the part with a laser exposure power and duration to obtain a temperature rise in essentially the entire volume of the part.

  • System and method for holding a workpiece in position for laser machining and/or welding thereof
    Patent number: 11498286
    Abstract: A system for holding a workpiece in position and exposing it to laser radiation, such that: the workpiece includes a bottom surface and a top surface that are electrically insulated from each other. The system includes an electrostatic charge generating device for generating electrostatic charges on the top surface; an electrically conductive support for forming, on the bottom surface, electrostatic charges of opposite sign to those generated on the top surface; and a laser device for machining or welding. The electrostatic charge generating device is arranged to be activated before or during the laser machining or welding, such that the workpiece is held in position relative to the electrically conductive support during the machining or welding thereof.
    Type: Grant
