Abstract: The method of forming a seamed metal tube having a metal coating of this invention includes applying a metal coating to the upper face of a metal strip prior to welding. The strip is then formed into an open seam tube and welded, preferably in a non-oxidizing atmosphere with the seam preferably located in the lower portion of the tube. Finally, at least a lower portion of said tube is reheated with the seam located in the lower portion of the tube, thereby causing the metal coating to flow downwardly over the seam, coating the seam. In one embodiment, the strip is preformed into an arcuate shape and coated, wherein the metal coating increases in thickness toward the lateral strip edges, such that the coating will flow over the seam following welding. The inside coated seamed tube may also be immersed in a galvanizing or metal coating bath to coat the outside of the tube. In a preferred embodiment, the inside and outside coatings comprise substantially the same metal and a single galvanizing bath apparatus is used to coat the inside and outside surfaces of the seamed tube. In another embodiment, the coating on the inner surface of the seamed tube has a melting temperature substantially below the melting temperature of the metal strip, but higher than the melting temperature of the outside metal coating.

Abstract: A profiled end cut is applied to a length of stock pipe in an apparatus wherein the pipe is rotated by a drive head with a plasma cutter moved axially on a trolley in synchrony with rotation under control of a guidance system. The guidance system follows a desired pattern to effect two adjoining end cuts in a single continuous operation. Pipe handling is effected by two sets of rollers, a support set permitting rotation and a lifting set to enable axial movement.

Abstract: An improved fluid fitting made from a portion of copper tubing has at least one annular cavity disposed in its inner periphery adjacent to each open end of the fitting. Solder is disposed in and substantially fills the at least one annular without extending beyond the inner periphery of the fitting. The fitting is fabricated by being placed in a die having a hollow with at least one annular depression. A first mandrel is placed into the fitting, with annular cavity forming ball members in substantial alignment with the at least annular depression of the hollow. The ball members are used to form the at least one annular cavity in the inner periphery of the fitting. A second mandrel has an aperture that substantially aligns with the at least one formed annular cavity and molten solder is injected into the at least one annular cavity through the second mandrel, to substantially fill the at least one annular cavity. The second mandrel forms an interference fit with the inner periphery of the fitting to remove any excess solder protruding from the at least one annular cavity into the inner periphery of the fitting as the mandrel is removed from the fitting.

Abstract: An improvement to orbital welding heads and welding systems for welding pipe and tubing butt joints, consisting of a removable or retractable detector module in the welding head for sensing the proper alignment of the welding head to the pipe joint prior to welding. The module contains a light source that shires a light beam on the pipe wall, and a detector with associated circuitry and output indicators to signal when the reflected light is interrupted by the presence of a seam or pipe joint. The module may be in the form of a battery powered module that with the use of sleeves fits into the viewing port of a variety of welding heads, or it may be an integral capability that retracts into the side of the weld head out of the way of the welding tip orbiting mechanism. The improvement extends to an automated traversing capability of the welding head along the pipe, in concert with the alignment sensor capability, to provide automated location and clamping of the weld head in the correct position of alignment for welding.

Abstract: A system is disclosed for forming metal tubing and, more particularly, brake tubing. The system includes a mill for rolling a metal strip into a tube so that at least a portion of the strip overlaps itself. The strip is then brazed so that the overlapping portions of the strip fuse together and form the tube. Thereafter, the tube passes through a cooling tunnel which cools the tube to a temperature such that the tube can be coated with a corrosion resistant material, such as a zinc based material. An inert gas, such as argon, and/or a reducing gas, such as hydrogen, is introduced into the cooling tunnel to prevent or remove oxidation of the tubing as it passes through the cooling tunnel.

Abstract: A tube such as a nozzle to be repaired or tubular sections to be repaired or connected to each other, are welded using a backing ring having a groove in the area to be welded. The groove forms a purge space for purge gas between the ring and the tube to establish an inert atmosphere on both inner and outer surfaces of the tube during the welding operation. The ring is removed by making a bore in the ring having a diameter larger than the diameter of the groove but smaller than the diameter of the ring. In this way, the ring is divided into two portions which are easily removed from the tube.

Abstract: The invention has as an object thereof to provide a welding method which is capable of forming an oxide passivated film, which is corrosion resistant, non-catalytic, and has an extremely small amount of released gasses, chiefly on the welded portion or in the vicinity thereof during the welding process. During the welding process, a gas in which 800 ppm.about.2.5% of moisture is contained in an inert gas is caused to flow, and a passivated film having chromium oxide as a chief component thereof is formed on the surface of the welded portion. The welding method comprises a welding process and a passivation process; in the passivation process, a gas in which 1000 ppm.about.2.5% of moisture is contained in an inert gas is employed. The apparatus is provided with a system for generating moisture, a system for supplying an inert gas or a mixed gas in which hydrogen is added to an inert gas as a back shield gas, a system for supplying a back shield gas comprising an inert gas containing moisture, and a mechanism for supplying these gasses to the portion to be welded via switching of both systems.

Abstract: A line-up clamp (10) is disclosed for clamping small diameter pipe sections together for welding. The line-up clamp includes back-up shoe assemblies (106) which are pivoted into engagement with the interior surfaces of the pipe sections adjacent the weld as the clamp clamps the pipe sections. As the hydraulic cylinder (14) compresses the resilient disks, expanding the disks into clamping contact with the pipe sections, actuator bodies (58, 88) are urged together, with tapered surfaces on facing back-up shoe assemblies moving into contact and driving the back-up shoe assemblies into contact with the interior surfaces of the pipe sections at the point of welding.
