4043 welding wire rod

Performance characteristics of 4043 welding wire rod:
4043 welding wire rod is a 5% silicon alloy welding wire, suitable for welding cast aluminum alloy
When the 4043 welding wire rod is used for AC argon arc welding, flux is not needed, because this is fusion welding. The argon arc welding fusion welding breaks the oxide film on the aluminum matrix surface through the cathode crushing action, and melts it by arc The matrix forms a molten pool, and then 4043 welding wire is added to the molten pool to form a weld.
 
Typical chemical composition of 4043 welding wire rod:
Si 5, Mg≤0.10, Fe≤0.04, Cu≤0.05, AL margin
 
 
Uses of 4043 welding wire rod:
4043 aluminum welding wire can be used for welding ships, locomotives, chemicals, food, sports equipment, molds, furniture, containers, containers, etc.
