ABSTRACT:
A method and apparatus for testing the weld strength of through-the-wall battery connections of the type having upstanding flat plate-like projections on opposite sides of the battery partition the testing being accomplished by application of shear forces to such connections parallel to the partition so that the structural integrity of weldments successfully resisting the test forces is not compromised. The apparatus includes anvil and pressure members which bear against opposite edges of the projections and a pneumatic cylinder formed to urge the anvil and pressure members toward each other parallel to the partition, thus applying a shearing force of desired magnitude controlled by the air pressure supplied to the cylinder.
