Zusammenfassung:	Exemplary pistons and methods of making the same are disclosed. An exemplary method generally includes providing a piston lower part defining a piston axis and at least a portion of the upper combustion bowl surface, and assembling a piston upper part to the piston lower part. The piston upper and lower parts cooperate to define at least in part an annular cooling gallery extending about the piston. The method may further include bringing the piston upper and lower parts together along respective upper and lower mating surfaces and inducing an electric current between the upper and lower mating surfaces while the upper and lower mating surfaces are in contact.
