This paper reports on the corrosion behavior of aluminum metal inert gas (MIG) welds reinforced with copper powder particles. Pure aluminum, AA1100 sheets, machined to a 45° v‐grooved were used for this experiment. Copper powder particle reinforced samples and unreinforced samples were investigated. The corrosion behavior of the samples were investigated in 3.5 % sodium chloride (NaCl) solution, using the potentiodynamic polarization technique. The results revealed that the corrosion resistance for reinforced samples were higher than those for unreinforced samples. Hence the corrosion resistance of aluminum AA1100 welds can be improved by the addition of copper powder particle in the weld seam, and it is therefore recommended for typical industrial applications.
