The invention relates to a method for laser welding two plastic components A, B brought into contact at least in the joining area, wherein component B facing away from the laser radiation consists of a plastic matrix with a white pigmentation of 1.5 5-20 wt.-%, and component A facing the laser radiation, through which the laser beam passes in the welding process, exhibits a plastic matrix. For a given laser wavelength the travel distance of the laser beam through the component A measures at most 10 mm, and given a white pigmentation of the component A in wt.-%, the product of the travel distance of the laser 10 beam through the component A in mm and white pigmentation in wt.-% is less than 1.25, and the travel distance of the laser beam through the component A measures at most 1 mm.
