摘要：
The arrangement relates to a method for producing a cooling duct piston for an internal combustion engine, having the steps of producing a top piston part by introducing a combustion bowl, a cooling space of a part of a cooling duct and overflow ducts, producing a bottom piston part by introducing a part of a cooling duct, and joining the piston parts, wherein at least one transfer duct is created by bores. A cooling duct piston produced by the method is disclosed.
