Experimental Work The material used for oxidation test was AA6061 aluminum welded joint and was fabricated by using gas metal arc welding (GMAW) technique with 22-25V and 185-200A, using filler metal Al-Si-Mg (ER4043).
Moreover, it is proven that Si-containing material showed enrichment in the oxide surface [8].
