Processing surface i.e. sealing surface, of metal construction part e.g. connector, of fuel system of combustion engine, comprises smoothening surface of metal construction part by supplying thermal energy using laser beam

摘要

The method comprises smoothening a surface (31, 32) of a metal construction part (25) by supplying thermal energy using a laser beam (18). A phase change is caused on the surface of the metal construction part in an impingement area of the laser beam from solid into a liquid phase, where the adjacent portions of the surface remain in the solid phase during the incidence of the laser beam. The surface roughness is changed by changing a process parameter value. The surface is machined by a rotational and/or translatory relative movement between the metal construction part and the laser beam.

The supply of thermal energy is exhausted in a gaseous phase to avoid impurities.
