Electron-Beam Welding. Experimental Results Achieved by the Initial Development Investigation and Their Applications are Described. G. Burton, Jr. and L. Frankhouser. Westinghouse Electric Corp. Welding J., 38, 401s-409s (1959) Oct.
A high-voltage electron-beam welding machine with a maximum beam power of 1 kw was used to make butt-joint weld penetration up to 0.250 in. in Zircaloy-2. Chemical analyses, metallography, corrosion tests, and mechanical-property evaluations have revealed satisfactory properties in the Zircaloy-2 welded by this process. The high-voltage (50 to 100 kv) electron-beam equipment has distinct advantages for extreme concentration of welded heat not realized with other processes nor with low voltage (5 to 50 kv) electron beam equipment. As a result, potential production applications are foreseen in welding fuel assemblies for the nuclear reactor industry. (auth)—NSA. 19633
