Abstract: A stairs rail connector which is pre-manufactured as a semicircular turning rail, including two curved tubes with identical dimension. Each curved tube has an interconnecting end and a connecting end. The interconnecting end of one curved tube is disposed with a shaft seat therein, while the interconnecting end of the other curved tube is disposed with a shaft ring therein, whereby the interconnecting ends are rotatably connected with each other, permitting the curved tubes to be freely 360 degrees rotated relative to each other. After the curved tubes are rotated to a position corresponding to the turning angle between an upper and a lower rails, the connecting ends of the curved tubes are inserted into and secured in the openings of the upper and lower rails to connect the same at the turning angle.

Abstract: In an automated final weld apparatus, a transporter conveys nuclear fuel-loaded cladding tubes successively to a check station to verify the presence of a plenum spring in the open end of each cladding tube, a reader station where a unique first end plug serial number is read, an evacuation/backfill station where the cladding tube is backfilled with helium, a seam welding station where a final end plug is welded to the cladding tube open end, and a seal weld station where the tube is pressurized with helium through a pressurization hole in the final end plug, whereupon the pressurization hole is welded closed. After checking for helium leakage, the seam weld is inspected in a succession of inspection stations, and, depending on inspection results, the finished nuclear fuel rods are sorted into accepted and rejected lots.

Abstract: An orbital welder includes a weld tip, a rotational controller, and a translational controller. The rotational controller causes the weld tip to rotate about an axis passing through the tube to be welded. As the weld tip rotates about the axis, the translational controller causes the weld tip to move longitudinally with respect to the axis, forming non-planar orbital welds. In one embodiment, the translational controller includes a rotor disposed to rotate about the axis. The translational controller further includes a carrier that is slidably attached to the rotor, and the weld tip is fixed to the carrier. As the rotor rotates about the axis, the carrier moves longitudinally with respect to the axis, such that the weld tip follows a non-planar orbital weld pattern. In a particular embodiment, a portion of the carrier is biased against a surface a cam block. The surface of the cam block is contoured to displace the carrier longitudinally with respect to the axis of rotation as the rotor rotates about the axis.

Abstract: A welding material supply mechanism for providing a welding bead on a surface comprising: a first hollow arm, a transfer tube, a second hollow arm, swivel bearing and a welding nozzle. The first hollow arm is connected to the second hollow arm by a swivel bearing, and a remote end of the second hollow arm supports a nozzle for facilitating welding on a surface. The swivel bearing facilitates pivoting movement of the second hollow arm relative to the first hollow arm to adjust a diameter of the welding bead to be formed on the surface, and a locking coupler facilitates locking the pivoted and adjusted position of the first hollow arm relative to the second hollow arm. The transfer tube is at least partially received within the first hollow arm and is concentric therewith. The transfer tube supports a female electrical connector coupled to the swivel bearing, the transfer tube establishes a welding electrical current path to the nozzle via the swivel bearing and the second hollow arm. A wire conductor is located within the transfer tube for supplying a welding wire to the nozzle, via the swivel bearing and the second hollow arm. A welding gas flow path is defined between an exterior surface of the wire conductor and an inwardly facing surface of the transfer tube to supply a welding gas to the nozzle via the swivel bearing and the second arm.

Abstract: A new hardfacing composition is disclosed. In addition, a pulsed plasma transferred arc method for depositing hardfacing material with a higher content of carbide and lower dilution by a substrate metal is disclosed. The disclosed method produces a hardfacing coating which has a strong metallurgical bond to the substrate metal. The method includesthe following steps: (1) establishing a transferred plasma arc between an electrode and an area of a work piece, (2) optionally preheating the work piece to at least 250.degree. F., (3) forming a plasma column of inert gas in the arc by passing an electrical current between the electrode and the work piece, (4) feeding a stream of hardfacing material in powder form into the plasma column, and (5) pulsing the current between a pre-selected high pulse current value and low pulse current value while feeding the powdered hardfacing material. In this method, the low pulse current is selected to be sufficiently high to melt at least one component of the hardfacing material. The pulse rate and the high pulse current are selected to minimize the formation of a weld pool on the metal substrate during the hardfacing process. This method has applications in hardfacing any metallic work piece which requires wear resistance or erosion resistance. This method is especially effective in hardfacing roller cone surfaces and the milled teeth of a rock bit for erosion and wear protection.

Abstract: A welding apparatus (28) for forming a circumferential weld (56) includes a base (30) and a spindle (32) extending perpendicularly from the base. Along the spindle, at its proximal and distal portions, first and second workpiece supporters (38, 40) are provided, respectively, to position workpieces (42) to be welded together therebetween. Between the first and second workpiece supporters, a first arm (44) and a second arm (48) are provided, both extending perpendicularly from the spindle. To a distal end of the first arm, an internal backup roller (46) is rotatably attached, and to a distal end of the second arm, an internal drive roller (50) is rotatably attached. One or more external rollers (52a, 52b), each rotatably attached to an external support (66), are further provided. The internal and external rollers are driven by variable-speed programmable motors (not shown). In operation, the workpieces are mounted onto the apparatus, being sandwiched between the internal rollers and the external rollers. A friction stir welding tool (58) is positioned externally with its probe opposing the internal backup roller. As the programmable motors drive the rollers to continuously draw the workpieces between the friction stir welding tool and the internal backup roller, the friction stir welding tool forms a circumferential weld to join the workpieces together.
