A crack susceptibility test for weld metals such as the alloys of titanium, aluminum and copper comprises filling a triangular pattern of grooves in a plate with weld metal wherein the groove arrangement provides the degree of restraint necessary to generate cracks in the weld metal. The grooves, which are fully contained in the plate, intersect to form a 30 deg. 60 deg. 90 deg. triangle, wherein the groove depth to plate thickness ratio is between about 0.2 and 0.8 Stress Testing.
