Wear-resistant camshaft and method of producing the same

The invention concerns a method for beam welding of hardenable steels using a short-time heat treatment. A preferred area of application of the invention is motor vehicle and mechanical engineering. In the method according to the invention, the short-time heat treatment occurs first as the sole preheating in a defined manner, and then the beam welding begins after a defined cooling time, at the latest.

Method for beam welding of hardenable steels by means of short-time heat treatment

In a process, the humidity of at least the exhaust air is measured and used for the regulation of the product humidity of water activity during a treatment process. Therefore, it is possible to directly register the humidity taken on by the inlet air or charged onto it, and to draw a conclusion about the humidity content of the product. To register the humidity value, a measuring device with moisture testers in the inlet air channel and in the exhaust air channel is provided. Especially the moisture tester for the exhaust air is constructed as a bypass flow moisture tester in an intrinsically safe manner, so that it can be used even under ex-conditions. During drying procedures, the possible measuring of the humidity charge of the exhaust air from the drying process, the course can be exactly controlled. The moisture testers can be constructed as dew point testers, especially with capacitive measuring probes.

Process for supervising and/or controlling of physical treatment

The invention relates to a method of drying a solid wetted with a solvent or solvent mixture by causing superheated vapour of the solvent or solvent mixture as a carrier medium to flow through the material to be dried in an evaporation room, the solvent or solvent mixture evaporating and being carried along with the carrier medium, and by then causing the evaporated solvent or solvent mixture to condense from the carrier medium, if desired after compression thereof, in a cooling device. During this drying process a sub-ambient pressure is provided in the evaporation room and the temperature in the evaporation room is controlled by adjusting the sub-ambient pressure, if desired, in combination with an additional temperature controlling means. The inventiona also relates to a device for using the above method.
