In a method for producing a piston () for an internal combustion engine, a melt treatment is performed at least in regions in particular in the region of a combustion chamber depression (), the depth of said melt treatment being varied in the circumferential direction.

Method for producing a piston for an internal combustion engine

The invention relates to a method for producing a piston for an internal combustion engine, wherein a section which in the finished piston has a cooling duct () and a piston ring groove is recessed at first, the later cooling duct is then covered, and finally material for accommodating the piston ring is applied, and which is characterized in that the later cooling duct is covered by a wire material which is provided in a length, greater than necessary for one single piston. A device for producing a piston for an internal combustion engine with an at first recessed section that in the finished piston has a cooling duct () and a piston ring groove, has a device for attaching a cover on the cooling duct and a device for providing wire material having a length greater than necessary for one single piston. A piston for an internal combustion engine has a cooling duct () and a reinforcement material for accommodating a piston ring as well as a cover material between the cooling duct () and the reinforcement material, wherein the cover material is made of wire material continuously unwinding from a roll.
