Aluminum Workshop: Busting the universal filler myth

November 4, 2014

By:

Q: My friend told me that he never worries about what grade of aluminum alloy he is welding on. He always uses 1100 filler. He says since 1100 is essentially pure aluminum and doesn’t contain any alloying elements, that you can use it to weld any aluminum alloy. Is this true? It would eliminate a...
