| 摘要 |
The invention refers to a procedure for a circuit wave welding, by welding alloy, during which circuit is contacted with at least a welding liquid material waving, obtained by pumping a welding alloy liquid bath, contained in a container, through a nozzle or mouthpiece, characterized in that each circuit face had been previously brought, under pressure proximal to atmospheric pressure, in front of gas outlet of at least an apparatus for excited or unstable gaseous species formation, wherein through apparatus an initial gaseous mixture (7) comprising an inert gas and/or a reducing gas and/or an oxidant gas is passed, obtaining at apparatus outlet a primary gaseous mixture (8) comprising excited or unstable species, and which is substantially devoid of electrically charged species.
