Abstract
A device and method for welding battery jar covers onto battery jars with the battery elements and terminal post in position within the jar and with a cover placed in position. The invention includes an exemplary welding apparatus that employs separate heating and clamping mechanisms on each side of the jar so that the cover does not have to be lifted completely off the jar during welding and this structure greatly reduces the time required to change over from one size to another thereby increasing the per unit processing capacity of the device. Further, in order that a variety of jar sizes be rapidly handled, two of the heating and clamping mechanisms are relatively long while the other two or relatively short and equal to the constant width dimension of batteries. The invention accomplishes the loading operation automatically and by not removing the cover fully from the jar better and more accurate welds are produced.
