  • Cooling channel piston for an internal combustion engine and method for the production thereof
    Patent number: 8485088
    Abstract: A method for producing a one-piece, lightweight piston consisting of steel and having a small compression depth (S) forms piston with at least one cavity in a shaft aperture region. A piston blank is produced in a first step using a forging or casting method. To form a cooling channel between an annular region and a combustion chamber recess an annular section is formed in one piece onto the wall of a cooling channel in the vicinity of the piston base. The joint produced between the annular section and an outer wall of the cooling channel is sealed by welding.
