Assembly for Testing Weldability of Sheet Metal

摘要

A test assembly for determining the weldability of sheet metal includes (1) a circular plate having an annular groove in one side thereof, a counterbore being formed in the outer wall of said groove and the surface portion of said base circumscribed by the inner wall of said groove being coplanar with the bottom of said counterbore, (2) a test disk of sheet metal the periphery of which is positioned in said counterbore and the outer surface of which is coplanar with said one side of said base, and (3) means for holding the periphery of said test disk against the bottom of said counterbore.
