The corrosion study of part aircraft at the site of spot welds in the salt spray environment

This bachelor’s thesis is focused on the corrosion study of part aircraft at the site of spot welds in the salt spray environment. The panel is made of sheet of aluminium alloy AlCu4Mg1, with surface coated with aluminium of purity 99,5 %, and of square shapes of alloy AlCu4Mg1, without coating. Square shapes are an angle cleat. The thesis deals with corrosion characteristics at the site of spot welds and in the area of contact between them. It deals with character of corrosion, frequency of occurrence and range of corrosive attack. From the data files were detected critical places of construction
