Abstract: A backside shield assembly for use during plasma arc welding. Two elongated closed boxes are supported in a selected spaced apart distance suitable for positioning the boxes on opposite sides of the backside of a weld line. Each box includes an inlet tube for an inert gas that generates a first side of the box and communicates with an elongated tube running along the inner surface of the first side. Perforations are provided in the elongated tubes. The balance of the interior of each box contains a flow diffusing material. The second box side, opposite the first side, is perforated. In use, the assembly is placed inside a conventional welding chill bar channel with the boxes on opposite sides of a weld line. The second surface is spaced slightly from the panel to be welded. An inert gas is directed through the inlet tubes, elongated tube perforations, diffusing material and out through the second side perforations. Since the only opening thereafter is oriented toward the volume between the boxes, the gas enters and fills that volume, where the weld flame and cooling weld bead are located. The gas covers the weld bead and prevents contamination from air borne contaminants.

Abstract: Tubing is made by advancing a flat metal strip in a travel direction along a path through a forming station and then through a soldering station and then through a cooling station. The strip is shaped in the forming station into a multilayer tubular shape by pressing it against a mandrel with a pair of forming rollers. Downstream the strip is engaged in the soldering station by a pair of contact rollers and electrical current is applied to the forming and contact rollers to flow via the forming and contact rollers through the tubular strip between the forming and contact rollers to heat the strip in the soldering station and thereby fuse layers of the tubular strip together. The forming rollers are rotated at a peripheral speed identical to a travel speed of the strip so that they do not slip on the strip, while the contact rollers are driven at a peripheral speed greater than that of the forming rollers. The soldered tubular strip is then cooled in the cooling station.

Abstract: A method of making a heat exchanger of the type used in vehicle radiators and having a core of spaced welded, as contrasted to lock-seam, tubes and interconnecting fins connected to spaced liquid tanks. The method, which permits machine-operated mass production of these exchangers, comprises stacking solder-coated core tubes in vertically spaced sets of a plurality of essentially horizontal tubes with serpentine fins located between each vertical pair of tube sets, arranging a top and a bottom rigid support plate against each of the topmost and bottommost tube sets, applying compression to the resulting stack through the support plates, banding the stack into an easily handled rigid assembly, applying a header plate to each essentially vertical side of the assembly with the tube ends extending through corresponding holes in the header plates, gang welding the projecting ends of the tubes to the exterior of the respective header plates by means of a movable multihead automatic welder, dipping this core assembly into a liquid soldering flux dip, blowing heated air at a temperature above the melting point of the solder over the outer surfaces of the core assembly to bond the fins to the tubes, applying a solder sealant coating over the adjacent junction areas of tubes and header plates that are opposite to the welds, the welds thereby being on the liquid side and the solder on the air side and finally removing the support plates and bands from the core and attaching the enclosing tanks to the header plates in fluid tight relation.

Abstract: A dual bias weld is an improved weld for joining strips to be formed into coiled tubing. Tubing is formed from a first strip and a second strip, the first and second strips being of the same width. A planar end surface is formed on an end of the first strip, the plane of the planar end surface being defined by a line lying along a top surface of the first strip at an acute angle with respect to the longitudinal direction of the first strip and a line lying along an edge surface of the first strip at an acute angle with respect to the longitudinal of the first strip. Similarly, a planar end surface is formed on an end of the second strip, the plane of the planar end surface being defined by a line lying along a top surface of the second strip at an acute angle with respect to the longitudinal direction of the second strip and a line lying along an edge surface of the second strip at an acute angle with respect to the longitudinal direction of the second strip. A composite strip is formed by welding the planar end surface of the first strip to the planar end surface of the second strip to form a dual bias weld. Excess weldment is then removed from top, bottom and edge surfaces of the composite strip such that the width of the weld is identical to the width of the first and second strips. Coiled metal tubing is then formed from the composite strip.

Abstract: In an arc welding process for welding pipes used to convey high purity gas, dispersion of particles into the pipes during welding is reduced by discharging an inert back shielding gas into one end of one pipe and holding the welding current at less than the normal welding current for a specified interval after the start of arc, the welding current thereafter being increased to its normal level.

Abstract: An improved method and apparatus for shielding inert gas from seeping out of metal pipes in a welding application wherein a high-temperature resistant purge strap is placed around the weld gap and the pipe ends. Advantageously, the purge strap is equipped with a window to allow the welder access to the pipe ends. Dams may be inserted into each pipe near the end to be welded, the purge strap placed about the pipes covering the end of each, and inert gas pumped into the pipes, displacing the air within the pipes. A weld bead is laid into the gap and the purge strap is shifted around the circumference of the pipes to allow completion of the weld. The purge strap device is also disclosed.

Abstract: Disclosed is a method of producing a welded steel tube with excellent inner surface corrosion resistance, in which at least one surface of a steel strip is coated with a first plate layer made of at least one of nickel, cobalt and alloys based on the metals, the plated steel strip is formed into a welded tube with the plated surface being inside, a film-forming material of at least one of tin and tin-based alloys is inserted into the inside of the welded tube and is then heat-treated at a temperature not lower than the melting point of the film-forming material by passing the tube through a continuous heating furnace having a non-oxidizing gas atmosphere therein so that the film forming material as inserted into the welded tube is fused and spread over the first plate layer to form a second plate layer thereon, and the tube is finally cooled. The welded steel tube of the present invention is free from cracks, pin holes, overplated spots and peeling of the plate layer and therefore has excellent corrosion resistance.
