The invention relates to a piston of an internal combustion engine including at least one peripheral annular groove. The piston includes an upper part and a lower part permanently joined in the region of a joining plane by a friction welding method. The joining plane may be located between the upper flank and the lower flank of the annular groove. A heat-affected zone is generated due to the use of the friction welding and includes at least one of the upper flank or the lower flank of the annular groove. Where multiple annual grooves are used, the joining plane and heat-affected zone may be positioned on alternate annular grooves.

Claim (Index 6):
The piston as claimed in  claim 1 , wherein the joining plane is located precisely centrally between the upper flank and the lower flank of the at least one peripheral annular groove.
