  • Process for producing tempered steel motor vehicle parts
    Publication number: 20070012384
    Abstract: A process for production of tempered steel support structures for motor vehicles of multiple steel parts including the steps deforming and/or trimming at least two soft-hardened steel parts, hardening the at least two steel parts, joining the steel parts to form a support structure, wherein the support structure is subject to annealing and total stress relieving in a combined thermal treatment only after the joining step.

  • Method and apparatus for plasma welding with low jet angle divergence
    Patent number: 6982395
    Abstract: The invention relates to a method and an apparatus for plasma welding. A free microwave-induced plasma jet is generated by the following steps. Microwaves are generated in a high-frequency microwave source. The microwaves are guided in a wave guide. A process gas is introduced at a pressure of p?1 bar into a microwave-transparent tube, which comprises a gas inlet opening and a gas outlet opening, the process gas being introduced through the gas inlet opening into the microwave-transparent tube in such a way that it has a tangential flow component. A plasma is generated in the microwave-transparent tube by electrodeless ignition of the process gas. The plasma jet is produced by the introduction of the plasma into a working space through a metallic expansion nozzle arranged at the gas outlet opening of the tube.
