ABSTRACT:
In joining heterogeneous materials that differ in their melting points, a shielding gas mixture with active gas content is utilized. In particular, the shielding gas mixture contains helium and active gasses in the vpm range (0.005 to 0.5% by volume). These shielding gases to lead to the production of high quality joints when joining aluminum and steel.
