In a survey of the various methods of measuring weldability by determining the ductility of the heat affected zone, no direct method was found which was applicable to the study of the weldability of steels in all thicknesses. The bead-weld nick-bend test is a weldability test designed to measure the effect of a welding technique upon the ductility of the heat affected zone of a steel. A test procedure is presented together with a discussion of variables affecting the bead-weld nick-bend test. The test procedure gives reproducible results and requires a test specimen which can be easily prepared using only a hack saw. Tests can be made under conditions closely simulating those encountered in practice with regard to steel composition, thickness of plate, brand of electrode and welding techniques actually used.
