Of course. The tab is made of aluminum and nickel, and the current battery processing plants are all welded by spot welding machine after nickel conversion.

If you don't replace the aluminum lug with nickel now, you can use low-temperature M5 1 welding wire with M5 1-F flux and electric soldering iron for welding.

If it is a nickel lug, it needs to be welded with WE88C welding wire with melting point of 250 degrees and WE88C-F flux, and an electric soldering iron.
