A method for the production of a piston for an internal combustion engine, composed of at least two components, each of which has at least one corresponding joining surface, has the following steps: a) pre-working the at least two components, at least in the region of the joining surfaces; b) coating at least a part of the surface of at least one component with a covering medium containing at least one phyllosilicate; c) assembling the at least two components; d) connecting the at least two components along their corresponding joining surfaces, by means of beam welding, to produce a piston blank; e) removing the covering medium and any excess weld material adhering to it; and f) machining the piston blank to produce a finished piston.
