_ Preheating – Drying

This application is used to treat all kinds of different materials. Since on reaching certain strength values through thermal process with subsequent quenching, it is possible for very hard structure constituents to form, which can cause cracks or fractures.

To prevent this phenomenon, for example, steels with a carbon content of more than 0.22 %, which are considered only conditionally weldable, are preheated constantly in the area directly next to the weld to a certain temperature, so that they cool more slowly and thus the formation of added hardness, brittle or crack susceptible areas is precluded.
