摘要：
As-welded AA6061 Al alloy using Al-Si-Mg (ER 4043) filler metal was subjected to oxidation exposure in flowing air gas for 40hrs at 600 degrees C at a total pressure of approximately 1 atm. SEM and EDAX were chosen to characterize the morphology microstructure of oxide formation on welded joint after oxidation process. Different oxide morphology were found on parent and fusion metal due to the differences of the alloying element. The morphology of the oxide shows the protection oxide surface were developed on parent metal while non-protective oxide formed on fusion metal.
