Title:
レーザプラズマハイブリッド溶接のための方法
Document Type and Number:
Japanese Patent JP2004535937
Kind Code:
A
Abstract:
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.
