A piston for an internal combustion engine includes a lower portion and an upper portion. An upper joining plane is positioned between the upper and lower extending through the outer circumference of the piston. At least one lower joining plane is positioned between the upper and lower portions. A solder gap is defined in the upper and lower joining planes wherein a solder containing iron is inserted to fixedly join the upper and lower portions together. Methods for producing pistons through connection of the lower portion to the upper portion with solder are also disclosed.
