    摘要： The invention relates to a process for laser-plasma hybrid welding, in which, to weld work pieces, a laser beam (10) and a plasma jet (11) are brought together in the process region close to the work piece. According to the invention, the free microwave-induced plasma jet (11) is generated by means of the following process steps: generation of microwaves in a high-frequency microwave source, guiding of the microwaves in a hollow waveguide (1) introduction of a process gas into a microwave-transparent tube (2), which comprises a gas inlet opening (14) and a gas outlet opening (15), at a pressure p≧1 bar, the process gas being introduced into the microwave-transparent tube (2) through the gas inlet opening (14) in such a manner that it has a tangential flow component, generation of a plasma (12) in the microwave-transparent tube (2) by means of electrode-free ignition of the process gas, generation of a plasma jet (11) by introduction of the plasma (12) into the working space (16) through a metallic nozzle (1) arranged at the gas outlet opening (15) of the tube (2).

    摘要： In a process for laser-plasma hybrid welding, to weld work pieces, a laser beam and a plasma jet are brought together in the process region close to the work piece. A free microwave-induced plasma jet is generated by the following process. Microwaves are generated in a high-frequency microwave source, and the microwaves are guided in a hollow waveguide. A process gas is introduced into a microwave-transparent tube, which includes a gas inlet opening and a gas outlet opening, at a pressure p≧1 bar. The process gas is introduced into the microwave-transparent tube through the gas inlet opening in such a manner that it has a tangential flow component. A plasma is generated in the microwave-transparent tube by electrode-free ignition of the process gas, and a plasma jet is generated by introduction of the plasma into the working space through a metallic nozzle arranged at the gas outlet opening of the tube.
