ABSTRACT:
Apparatus and method for induction heating "over-the-partition" intercell connections in a lead/acid storage battery by melting both lead risers so as to form a connection over the top of the insulating partition. A mold is suspended on top of the partition and an induction coil is supported on the mold so as to surround the top portion of the intercell lead risers. High frequency alternating electrical current is applied to the coil so as to melt the top portion of the lead risers so that upon fusion thereof in the mold and cooling, the tops of the risers are interconnected. The interconnection bridges the top of the risers and rests on top of the partition. The invention lends itself to mass production in a very short time as compared to present methods. Excellent fusion quality is reliably obtained as compared to present methods.
