ABSTRACT:
In a cooled composite piston having a cooling passage adjacent to the interface and a method of making same, the upper part consists of forged steel and is formed on its underside with ribs bearing on mating surfaces of the lower part. To improve the resistance to thermal and mechanical stresses, the upper part has been welded by means of charge carrier rays to the lower part, which consists of cast ferrous material.
