Verfahren zum Lichtbogen-Hartlöten unter Schutzgas

摘要

The inert gas mixture for MIG/MAG arc brazing having argon as main gas component contains 0.2 to 1.2 percent by volume O2. The inert gas mixture is used in the method for MIG/MAG arc brazing of zinc materials, wherein the method operates in a low current range, preferably at a soldering speed of 0.3 to 1 m/min in a short or pulsed arc range with a welding wire fusion efficiency of 3.5 to 8 m/min.
