摘要:
The invention relates to a piston, especially a cooling channel piston (1) of an internal combustion engine, having a first part (2) and a second part (3) and a third part (8). These parts can be produced separately from each other and subsequently be assembled by way of a joining method. One part, especially the third part (8) comprises, in direction of one part, especially the first part (2), at least one rotationally symmetrical joining area, and, in the direction of the other part, especially the second part (3), likewise an at least rotationally symmetrical joining area. Said joining areas mate joining areas of the two parts, especially the first part (2) and the second part (3).
