Abstract
An extruder and electrode assemblage for interconnecting the upstanding lugs of plate straps connected to the positive and negative grids of battery cell units through apertures provided in partitions, separating the cell units of a battery from each other. The electrode assemblage not only clamps the lugs against the partition but defines apertures for the extruding plungers to engage the lugs and extrude same into the partition aperture. Once the extruded lug portions contact each other, welding current is supplied thereto in a semi-annular path by the electrodes.
