摘要： An apparatus, system and related method are disclosed for performing trackless movement and full penetration welding along a weld line, irrespective length and configuration of a butt joint. A pre-existing gap of the weld line is used to act a guide slot and a guide wheel unit to track the gap is designed to perform trackless movement using an electric or manual winch as a driver. In the automatic arc welding systems, the guide slot and the guide wheel unit can save an external track and a seam-tracking device. A movable weld backing is held against the underside of the weld line to support liquid metal and control backside bead to achieve full-penetration welding of a butt weld. The movable weld backing and a welder are arranged the underside and the topside of base metals to be welded, respectively, using a connector member through the pre-existing gap of the weld line. According to the apparatus, flux-cored wire plasma arc can perform full penetration welding. A layer of liquid slag between the moveable backing and the liquid metal of the underside weld pool can act as a lubricant to increase the sliding ability of the moveable backing, act as a heat insulator to protect the backing from the high temperature of plasma arc, and provide a shielding film for the weld pool.

摘要： A weld bead is disposed between two workpieces to be welded together by feeding the weld metal to a pool which is advancing relative to the workpieces while supporting the pool of weldment from below with a member which simultaneously serves to maintain the spacing of the workpieces and is preferably composed of tungsten. The support member can be constituted as an electrode. The pool-support member and the burner form a unit which is displaced along the welding gap between the workpieces.

摘要： A flux backup unit applies a continuous flow of granular flux to the underside of a joint as a weld is made at that joint. The backup unit includes a hopper, an open top container within the hopper, and a feed screw for lifting the flux from the bottom of the hopper to the container. The continuous flow of flux into the container causes the container to remain full as the joint is moved relative to it so that the joint is continuously backed with flux. The excess flux introduced into the container overflows into the hopper and is thereby automatically recirculated through the container by the feed screw.

摘要： The present disclosure is directed to methods for damming and backing welds. In one embodiment, a method of welding a workpiece is provided in which the workpiece includes a first section, a second section, and a weld groove disposed therebetween. Opposing edges of the first and second sections are positioned adjacent to each other and at least partially form a bottom of the weld groove. A silicon dioxide weld dam is abutted against a terminal end of the workpiece relative to a weld direction. The weld dam is positioned at a weld joint termination point to prevent molten metal from flowing through a terminal end opening of the groove at the weld joint termination point. The first and second sections are welded together along opposing edges in the weld direction up to the weld joint termination point. Finally, the dam is removed, exposing the terminal end of the workpiece.

摘要： An apparatus for building an axially symmetrical workpiece of desired geometry by deposit welding which uses a welding head 18 for depositing molten weld material 14 and a rotatable, reusable preform 10 which translates with the welding head 18. The reusable preform 10 is provided with means for varying its shape 22 to minimize the weight of the preform 10. The rotatable, reusable preform 10 forms, supports and cools the deposited molten weld material puddle 14 while the weld material is solidifying thereby eliminating the need for a conventional consumable preform.
