Abstract: 1,233,094. Welding by fusion. UNITED AIRCRAFT CORP. 30 May, 1968 [8 June, 1967], No. 25996/68. Heading B3R. [Also in Division H1] Pipes are welded end-to-end by an electron beam or like welding device orbiting the pipes in an evacuated annular chamber 16 surrounding the joint. The welding device and a pipe 10, Fig. 1, are supported by a pipe-laying vehicle. A locating strap 24 is secured to the pipe 10 at a distance from the pipe end determined by the use of guaging levers 30 pivotally mounted on the strap 24. An aligning tool 32 is inserted in the pipes 10, 12. The welding device is suspended from a boom 14 and has an annular chamber 16 in two or as shown three parts 18, 20, 22 hinged together. The parts are closed about the pipes by rams 43 and are locked by a power mechanism 23. A welding carriage is driven in either direction on rails on the sides of chamber by engagement of a motor-driven pinion on the carriage with a rack on the chamber. An electron beam welder carried by the welding carriage generates a beam which is bent through 90 degrees to issue in a radical direction. The aligning tool 32, Fig. 7, carries a vacuum pump 127 for evacuating annular recesses on either side of the seam and housing expanding clamps which grip and shape the pipe ends. Inflatable seals 128 are provided on the annular chamber 16 and the aligning tool 32. An expendable ring 132 in a central recess 130 protects the tool 32 from the beam. The current supply cables 48, Fig. 5, are brought into the chamber 16 by two reels 114, 116 inside and outside the chamber 16 respectively and joined by a hollow shaft 118 journalled in bearings in the wall of the chamber 16. A two part seal 122 is provided, and the intervening space is evacuated. The cables 4, 8 are oppositely wound on the reels 114, 116 and pass through and are sealed in the shaft 118 by a block 120. Thus rotation of the reels by a constant torque motor simultaneously retrieves or pays out the cables 48. In operation the welding carriage is driven round the pipes 10, 12 while the chamber 16 is evacuated. A platform 86, Fig. 4 pivotally attached to the welding carriage is connected to a pivoted arm 91 by springs 93, 95, which is oscillated by cam surfaces 110 on the chamber to oscillate the platform 80 until a spring-loaded wheel 76 engages in the seam 74 to be welded which for this purpose is provided with bevelled edges. The platform 80 also carries a guide through which filler wire is fed to the welding zone. During welding the welding carriage is driven in the reverse direction and the arm 91 having spring-loaded pivoted ends 90, 92 is unaffected by the cams 110. The wheel 76 follows the seam and deviations of the seam cause the platform 80 to pivot relative to the welding carriage to produce an electric signal arranged to control the beam deflecting coils to direct the beam accurately on to the seam 74. A continuous circular movement is superimposed on the beam. The device feeding the filler wire is electrically or mechanically linked to the welding carriage drive.
