Abstract
The invention relates to a process for manufacturing a single-piece cooling channel piston, where a piston blank produced by forging is furnished with a circumferential ring-shaped recess between the piston skirts and the piston crown and with an open-bottomed cooling channel in the area of a piston ring belt, where to increase the surface guidance area of the piston skirts it is envisioned that a component extending this piston ring belt is welded on below the piston ring belt.
