| description | The invention relates to a method for the manufacture of a part of a structural component of a vehicle, intended to be connected by spot welding to a second part, starting from a coated steel plate and of a thickness of 1-3 mm, which comprises subjecting the plate to hot stamping, subsequently subjecting at least one localized and previously selected zone of the first part to a heat treatment, irradiating it with a diode laser beam of a power comprised between 500 W and 6 kW until reaching a temperature comprised between 400-900 °C, then leaving it to cool to change its microstructure, providing said zone with an intentionally lower martensite content and accordingly with a lower strength and greater elongation in comparison with those of its adjacent zones that have not been heat treated. |
