Apparatus for shear testing welds

Abstract

A device for non-destructively simultaneously testing the shear strength of at least four welded joints presented by a metallic truss having two spaced substantially parallel chord members joined together by a substantially coplanar web member bent into a substantially uniform undulating configuration between the chord members so as to present a series of alternate opposite apices at the bends welded to the spaced chord members respectively along regularly spaced intervals longitudinally of the chord members, the device including; elements for simultaneously clamping the chord members in at least four positions adjacent the welded joints, including elements for eliminating the twisting of the welded joints from the plane defined by the web member during the simultaneous clamping, and elements for simultaneously applying a substantially perpendicular force relative the plane defined by the web member, for a selected timed interval, to at least four of the apices defined by the bent web member, adapted to test the shear strength of at least four of the welded joints.
