Abstract

See full text

A piston for an internal combustion engine and a method for producing a piston are disclosed. The piston includes an upper piston part and a lower piston part that together delimit a circumferential cooling channel for receiving a cooling medium both radially inside and radially outside. The upper piston part and the lower piston part are connected to one another via a radially outer weld connection and a radially inner weld connection. The radially outer weld connection includes a radially outer weld bead that projects radially inwards into the cooling channel for forming a deflection element for the cooling medium received in the cooling channel.
