Oxidation Effect on Welded AA6061 Al Alloy Using ER4043 Filler Metal
As-welded AA6061 Al alloy using Al-Si-Mg (ER 4043) filler metal was subjected to oxidationexposure in flowing air gas for 40hrs at 600oC at a total pressure of approximately 1 atm. SEM andEDAX were chosen to characterize the morphology microstructure of oxide formation on welded jointafter oxidation process. Different oxide morphology were found on parent and fusion metal due to thedifferences of the alloying element. The morphology of the oxide shows the protection oxide surfacewere developed on parent metal while non-protective oxide formed on fusion metal.
