A method for producing a piston for an internal combustion engine, which piston has at least one cooling channel and is produced from at least one upper part and one lower part. The cooling channel of the piston is formed of the upper part and the lower part where the upper part and the lower part of the piston are each produced by means of a forging process At least one rib-like element, in particular, at least one rib, is additionally forged during the forging of the upper part an area of the cooling channel and/or at least one rib-like element, in particular, at least one rib, is additionally forged during the forging of the lower part in an area of the cooling channel. Two alternative production methods and to a piston for an internal combustion engine are disclosed. |
