Abstract

In a process for producing a piston for an internal combustion engine, a groove is worked into a cast piston blank proceeding from a combustion chamber cavity (20) in a largely radial direction and then closed to form a cooling duct. A cast piston for an internal combustion engine has a closure which is fitted after the casting and the machining between the cooling duct and a combustion chamber cavity (20).
