Abstract:
The invention relates to a method for producing a piston (1) for an internal combustion engine. The inventive method comprises producing the base (4) from aluminum by a forging process, casting, by way of a composite casting process, a ring support (10) which is provided with a cooling channel (15) into an aluminum ring element (6), and then welding the ring element (6) with the base (4).
