Modification of Aluminum Alloy Filler to Improve Arc-Welding Performance


Al-Mg alloys are widely used as GMAW and GTAW filler electrode for their high strength and compatibility with a large variety of aluminum grades. Compared to 4000-series filler alloys, Al-Mg alloys have less favorable welding characteristics such as spatter, fume, arc stability and puddle fluidity due to their high magnesium content. Low levels of alloying elements were added to AA5356 and these modified chemistries welding performance were assessed in GMAW and compared to the unmodified alloy. The modified alloys have shown significantly lower spatter, higher arc stability and better puddle fluidity than the baseline alloy. The improved welding performance is likely due to the effect of the alloy addition on metal transfer and surface tension.
