Abstract

1419838 Welding by fusion BELGONUCLEAIRE SA and CENTRE D'ETUDE DE L'ENERGIE NUCLEAIRE 26 March 1973 [30 March 1972] 14352/73 Heading B3R [Also in Division G6] In preparation for TIG or plasma butt welding together a tubular casing and plug of a nuclear fuel rod, e.g. of Zircaloy or steel, the plug is formed tubular and open at one end and the plug tubular end and casing are end edge chambered respectively externally and internally or internally and externally to provide for plug/casing centering. Each chamfer is between 15-75 degrees to the axis of the plug and casing. To prevent edge deformation, the chamfers are preferably provided with end flats. As shown, an externally chamfered plug tubular end portion 14 is of internal diameter less than that of the casing 12 to provide for molten pool support. In Figs. 4a, 4b (not shown), an externally chamfered plug tubular end portion (24) has an external end ridge to provide a weld seam reinforcing metal supply. The Specification refers to rotary welding and to use of helium shielding gas.
