As is the case in any thermal process, soldering often entails an undesirable embrittlement of the material structure.

Soldering is a method of cohesively joining materials by producing a liquid phase by melting a solder. In contrast to welding, the liquid temperature of the basic materials is not reached. After the solder has solidified, a cohesive connection is produced.

Furnace soldering, which excludes any stresses in the material structure thanks to uniform heating of the parts to be joined is therefore very advantageous to avoid undesirable changes in the material structure.

The parts to be joined are heated in a furnace with the solder inserted, and oxidation of the cleaned parts to be joined is prevented in a targeted manner by isolating the air in the furnace or by adding a protective gas. Various solder points can be produced in one working step without using a flux and at the same time, i.e. during the same working step (!), the base materials can be heat treated. These furnaces operate either in batches such as the batch or shaft furnaces or continuously with a conveyor belt.
