ABSTRACT:
A fixture for testing the strength of a resistance spot weld connecting two test strips comprises two identical clamping frames, each having releasable clamps for gripping and holding one of the test strips. A pull bar is mounted on each clamping frame in any one of several selected angular positions. The pull bars are aligned with one another and then grasped by a pulling mechanism to apply a separating force on the two strips. The arrangement is such that the line of the separating force passes through the weld.
