Abstract: Solid phase or pressure welding of adjacent pipe ends is accomplished by placing a pair of expandable elements maintained in axial alignment within the pipe ends and radially expanding the elements into firm grasping relationship with the interior bore walls of the respective pipe ends. Thereafter, the elements are axially moved together to place and hold the pipe ends in axially aligned abuttment and create upset pressure in the region of the abutting ends while heat is applied thereto to produce a solid phase welded joint between the pipe ends.

Abstract: 1357820 Welding by pressure J LA FORCE and C STRINGER 22 Oct 1971 [1 June 1971] 49174/71 Heading B3R In solid phase welding adjacent ends of axially aligned pipes 11, 12 the pipe ends are grasped, only interiorly, by a pair of elements 17, 18, one per pipe, using radial outward pressure at substantially uniformly spaced locations about the circumference of each pipe, the ends are urged together by causing relative axial movement of the elements 17, 18, an exterior source of heat is applied around the entire periphery of the abutting pipe ends and the axial pressure on the pipe ends is increased before the heat applying step is terminated. The element 17 within the pipe 11 comprises a cylindrical body 29 having radially arranged bores 32 receiving the shanks 33 of pressure pads 34 and having a shaft 31 coaxially extending towards the pipe 12. The element 18 within the pipe 12 includes a cylindrical body 36 having radially arranged bores receiving the shanks of pressure pads as in element 17 and has a central bore through which passes the shaft 31 into a cylinder 49 secured to the inner face of the body 36, the shaft 31 having a piston 52 slidable in the cylinder 49. In operation hydraulic fluid from a source 46 is supplied via conduit 44 to urge the pads 34 into firm contact with pipe 11, fluid is supplied to move the element 18 into the pipe 12, fluid is then supplied via conduit 48 to urge the pads of element 18 into firm contact with pipe 12 and fluid is supplied via conduit 36 to move the element 17 and thus pipe 11 towards pipe 12 to bring the pipes into abutting relationship under a predetermined pressure. Heat is supplied to the entire joint area of the abutted pipe ends by a burner ring and, when upset is initiated under the applied pressure, the axial pressure is increased. When the desired upset is obtained heating is terminated and the axial force released. Argon may be directed to the interior of the joint.

Abstract translation: 相邻管端的固相或压焊是通过将一对可膨胀元件放置在管端内保持轴向对准并且将元件径向膨胀以与相应管末端的内孔壁牢固地夹紧的关系来实现的。 此后，元件被轴向移动在一起，以将管端保持在轴向对准的邻接处，并且在加热的同时在邻接端的区域中产生压缩压力，以在管端之间产生固相焊接接头。

Abstract: A consumable wire guide electrode for producing a high alloying effect on the weld deposit includes spaced inner and outer tubes defining a void therebetween filled with an alloying material and binder, the bore of the inner tube serving as a guide for the feed of a continuous wire electrode therethrough. The outer tube is advantageously exteriorly coated with flux such that as the wire and guide are consumed by an electric arc, a pool of alloyed weld metal with flux floating on the top is produced.
