Abstract: An end portion of each of two parts is machined and the machined end portion of the parts are arranged in facing positions to form a welding bevel extending in a longitudinal direction between the parts, whereafter a filler metal is deposited into the welding bevel. The welding bevel is a narrow bevel with side walls at an aperture angle of no more than 5° relative to the longitudinal central plane of the bevel. A nickel alloy comprising 18-32% of chromium is deposited into the welding bevel. The method is particularly suitable for joining a pressurized water nuclear reactor vessel tubing and an austenitic stainless steel primary circuit pipe.

Abstract: The welding electrode (21) moves rotationally about the axis (23) of the cylindrical piece, so as to lay down, one on the other, layers each covering the entire width of the bevel (16). The speed of rotation of the electrode (21) about the axis (23) of the cylindrical piece (14) is varied and the electrode (21) is moved translationally along the direction of the axis of the cylindrical piece. The device includes means for adjusting the speed of rotation of the electrode (21) and means for moving the electrode along the direction of the axis (23). The process may be used in particular to weld a replacement adaptor (14) to the head of the vessel (1) of a nuclear reactor.

Abstract: An end portion of each of two parts (10, 11) is machined and the machined end portions of the parts (10, 11) are arranged in facing positions to form a welding bevel (13) extending in a longitudinal direction between the parts (10, 11), whereafter a filler metal is deposited into the welding bevel (13). The welding bevel is a narrow bevel with side walls at an aperture angle of no more than 5 DEG relative to the longitudinal central plane of the bevel (13). A nickel alloy comprising 18-32 % of chromium is deposited into the welding bevel. The method is particularly suitable for joining a pressurised water nuclear reactor vessel tubing and an austenitic stainless steel primary circuit pipe.

Abstract: PCT No. PCT/FR96/01838 Sec. 371 Date Jul. 28, 1998 Sec. 102(e) Date Jul. 28, 1998 PCT Filed Nov. 20, 1996 PCT Pub. No. WO97/22432 PCT Pub. Date Jun. 26, 1997The machined ends of two parts (2, 4) are arranged in facing positions to form a welding bevel (6) between the parts (2, 4). A series of layers of filler metal are deposited one on top of the other in the welding bevel (6) in a direction thereof corresponding to the width of the parts (2, 4), by melting a wire (14) supplied at a predetermined feed rate to an electric arc between the parts to be welded and an electrode (13) supplied with a predetermined welding current and voltage. Each layer of filler metal essentially consists of a single weld bead across the full width of the bevel (6). The electric welding current and voltage and the feed rate of the wire (14) are predetermined in accordance with the width of the bevel (6).
