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.
