Abstract

Shielding gases entering a welding torch are oscillated by a device fitted on or around the gas supply line. A pipe may be used to induce oscillation or an electrical, mechanical or acoustic oscillation unit. A mechanical unit may be operated by solid, liquid, or gaseous media. Units can be mounted on conventional torches used for gas-shielded non-consumable or consumable electrode welding processes.

Description

Die Erfindung betrifft die Impulsmodulation von Gasen zur Stabilisierung freier Gasströme wie sie bei der Schutzgasschweißung vorkommen.The invention relates to the pulse modulation of gases to stabilize free gas flows as they occur in inert gas welding.

Im vorgegebenen Beispiel von MIG/MAG und WIG-Schweißbrennern kann das Schwin­ gungsaggregat in, an oder um die Zuführungsleitung angeordnet werden und die noch ge­ bunden geführten Gase in Schwingungen versetzen.In the given example of MIG / MAG and TIG welding torches, the Schwin can supply unit to be arranged in, on or around the feed line and the still ge cause the guided gases to vibrate.

Es sind mir keine Verfahren bekannt, welche die Impulsmodulation zur Stabilisierung freier Gasströme bewirken.I am not aware of any methods that free pulse modulation for stabilization Cause gas flows.

Der Erfindung liegt die Aufgabe zugrunde, durch Impulsmodulation freie Gasströme zu sta­ bilisieren und das Eindringen des Umgebungsmediums, z. B. Luft, in den freien Gasstrom zu verhindern:The invention has for its object to sta free gas streams by pulse modulation bilize and the penetration of the surrounding medium, for. B. air, in the free gas flow to prevent:

Am Beispiel von MIG/MAG und WIG-Schweißbrennern wird die Schweißnahtqualität erhöht und der Schutzgasverbrauch gesenkt. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The weld seam quality is increased using the example of MIG / MAG and TIG welding torches and reduced shielding gas consumption. This task is characterized by the Features of claim 1 solved.

Die Erfindung hat den Vorteil, daß die Impulsmodulation der Gase mit kleinsten Schwin­ gungsaggregaten preiswert bewirkt werden kann. The invention has the advantage that the pulse modulation of the gases with the smallest Schwin supply units can be effected inexpensively.
