ABSTRACT:
A method for producing pore-free cast-on-strap joints for lead-acid batteries including the steps of cleaning a plurality of positive and negative plate lugs by a combined action of flux and ultrasonic vibration, water rinsing the plate lugs under ultrasonic vibration, and drying the plate lugs by gas blasting. The gas blasting occurs prior to the formation of the cast-on-strap joint. The cast-on-strap joint is formed by introducing the plate lugs into a molten lead-based strap alloy contained in a strap mold and solidifying the molten strap alloy in the strap mold.
