Research on the Weldability of Iron Alloys the Bead-Weld Nick-Bend Test for Weldability

摘要

A survey of the various methods of measuring weldability by determining the ductility of the heat affected zone, sought a direct method which was applicable to the study of the weldability of steels in all thicknesses. The Bead-Weld Nick-Bend Test is discussed as 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.
