Abstract:
A method for producing a piston may include producing a piston top part and a piston bottom part each including an inner support element having an inner joining surface and an outer support element having an outer joining surface. At least one of the joining surfaces may include a solder depository. The method may also include pre-machining at least one of the joining surfaces and introducing a high-temperature soldering material in at least one solder depository. The method may further include assembling the piston top part and the piston bottom part to form a piston body via creating at least one of circular contact and linear contact between the joining surfaces such that a gap width is 20 μm to 150 μm. The method may also include transferring the piston body into a soldering oven, melting the high-temperature soldering material via heating the piston body, and cooling the piston body.
