METHOD OF EXTRUSION-FUSION WELDING OF LEAD PARTS THROUGH AN APERTURE IN A BATTERY CASE

摘要

METHOD OF EXTRUSION-FUSION WELDING OF LEAD PARTS THROUGH AN APERTURE IN A BATTERY CASE The present invention provides a novel method of extrusion-fusion welding of lead parts through an aperture in a battery case which uniformly controls the area of contact between members to be welded at the completion of the extrusion process in order to produce consistent, high-quality welds exhibiting higher strength and superior durability.
