... 5083 or 5086. Analysis of the weld metal indicated that aluminum alloy 4043 filler metal had been used. The silicon content was lower and the magnesium and manganese contents were higher than normal for alloy 4043 filler metal. These differences were attributed to dilution of the weld metal by the base...
