The present subject matter relates to a method for manufacturing a vehicle interior trim part comprising a decor layer which forms a groove, as well as a decor element which is welded in the groove) of the decor layer, wherein the decor element is brought into the groove and is subsequently fixed in the groove by way of welding. According to the present subject matter, a welding head, e.g. an ultrasound sonotrode, is used for welding, and this comprises a contact side which is equipped with a plurality of projections which are arranged distanced to one another in a row and which taper to their contact surfaces, and wherein the welding head for producing the seam is pressed against a rear side of the decor layer in the region of the groove, in a manner such that the individual projections of the row of projections in a longitudinal directions of the groove come into contact with the rear side of the decor layer in a manner offset to one another, wherein the projections have a width which corresponds at least to 50% of a width of the decor element.
