ABSTRACT:
Method and apparatus for joining lead battery parts (e.g., plate lugs, intercell connectors, terminals, etc.) together via a low resistance electrical coupling wherein substantially oxide-free, arc-melted, superheated molten lead is cast into a cavity between the parts. The parts are shielded from the arc while being bathed in a non-oxidizing atmosphere which is preferably formed from an ionizable, non-oxidizing gas heated by the lead-melting arc and spewed onto the parts along with the molten lead to provide additional heat thereto.
