For welding aluminum, you typically use aluminum welding wire such as ER4043 or ER5356, depending on the alloy and application. ER4043 is common for general-purpose welding, while ER5356 is preferred for higher strength and better corrosion resistance. Always match the wire type to the specific aluminum alloy being welded for best results.
