Abstract
A method for the production of a one piece piston for an internal combustion engine. The piston has a ring shaped cooling channel arranged in an outer region of a piston head. The channel is partially closed off by a circumferential projection structured as an oil groove. The piston is produced in a simple and inexpensive manner using a piston blank using cutting work such as lathing.
