Oxidation Effect of Welded AA6061 Al Alloy Using ER5356 Filler Metal

Abstract:

Test material of welded AA6061 Al alloy using ER5356 (Al-Mg-Si) filler metal was oxidized inflowing air gas for 40hrs at 600oC at a total pressure of approximately 1 atm. The morphology andmicrostructure of oxide formation on welded Al alloy was characterized using SEM and EDAX.Different oxide morphologies were observed on parent and fusion metal due to the differences of thealloying element. The oxidation mechanism represented a complex reaction where the morphology andphase formation of the oxide shows the protective oxide were developed on parent metal side, whilenon-protective oxide formed on fusion metal of the welded Al alloy.
