Abstract: A robot supports a welding torch for use in arc welding of a cylindrical welding object. The welding object is rotated about an axis and is controlled by a robot controller. The robot is operated to track the welding torch along a calculated welding line to continuously position the welding torch along the welding line. A reference circle is formed by rotation of one point on the welding object. A coordinate system is set with a center corresponding to the center of the reference circle. A laser sensor detects a point on the welding line, and the detected point is stored by using a distance r from a center O of the work coordinate system and a z-coordinate value z. As the cylindrical welding object is rotated by an angle .theta. corresponding to an interval between the position detected by the laser sensor and a calculated second position, the welding torch is moved to a position to coincide with the second position.

Abstract: An I.D. pipe clamp used for holding the ends of two pipes during welding, and having a means for inspecting the inside diameter of the root pass of the weld without removal of the pipe clamp or breaking of the purge gas seal. The pipe clamp has a frame with two clamping mechanisms for locking the clamp in position within the pipe ends. A means for inspecting, such as a video camera or other nondestructive testing device, is mounted on the pipe clamp between the two clamping mechanisms. Gas purge dams are located proximate each clamping mechanism to facilitate the creation of an inert gas purge in the region of the weld joint. The means for inspecting is operated to inspect the root pass of the weld prior to breaking the gas purge and prior to removal of the pipe clamp. The pipe clamp may also support a means for dressing of the weld I.D., such as a brush or a grinding tool, along with a vacuum line for removal of debris created during operation of the means for dressing.

Abstract: The method of forming a seamed metal tube having a metal coating of this invention includes galvanizing the strip prior to welding. The strip is then formed into an open seam tube and welded in an inert atmosphere with the seam located in the lower portion of the tube. Finally, the metal coating is caused to flow downwardly over the seam, coating the seam by several means. In one embodiment, the strip is preformed into an arcuate shape and galvanized, wherein the zinc coating in creases in thickness toward the lateral strip edges, such that the coating will flow over the seam following welding. The tube may also be reheated following welding, preferably in an enclosure containing an inert atmosphere which includes the weld apparatus. In an other embodiment, an inert gas is directed over the inner and outer surfaces of the tube, adjacent the seam, driving the molten metal downwardly over the seam to coat the seam. In another embodiment, the lateral edges of the strip are formed with indentions or grooves directed toward the lateral edges which direct the molten metal downwardly over the seam.

Abstract: An internal welding fixture is disclosed for locating and temporarily retaining two tubular workpieces relative to one another. The internal welding fixture includes a plurality of shoe assemblies, each of the shoe assemblies being radially disposed about a single axis and being radially movable between a contracted position and an expanded position. The shoe assemblies are equally divided into first and second groups of shoe assemblies. The internal welding fixture further includes a drive arrangement operatively connected to each of the shoe assemblies for moving each shoe assembly between its contracted position and its expanded position. The shoes of one of the groups of shoe assemblies are interconnected to the actuator through a delay mechanism which serves to mechanically delay retraction. Upon expansion of the shoe assemblies, the internal welding fixture is operative to reinforce and temporarily retain a joint formed between two tubular workpieces during a joining procedure, such as welding.

Abstract: A method for upgrading/repairing existing piping systems of a nuclear reactor without removal/replacement of the old piping. The process involves the steps of machining a counterbore of exposed corrosion-susceptible material and then depositing a corrosion-resistant weld material, thereby isolating the weld joint from corrosion susceptibility. A tool is inserted into the inside diameter of the piping system through an inspection port, valve body or segment removal. Then a tool mounting fixture equipped with axial and rotational capabilities is positioned in relation to the weld joint and locked in place. The tool mounting fixture remains locked in place throughout the entire repair process. A work surface mapping module is programmed to first gather relative reference points throughout the entire repair region. Upon data acquisition completion, the system creates a map of the existing inside diameter configuration. Then in successive stages, a machining head module and a welding head module are respectively manually installed and remotely operated by computer control. The machining and welding processes follow the existing configuration such that upon completion, the final repair blends with the piping inside diameter contour.
