Abstract: The present invention relates generally to both a system and method for visually (e.g., via a video-based system or some other visual system) monitoring one or more objects where such objects are obscured by a high intensity light source such as a plasma, flame, or welding arc. In one embodiment, a system in accordance with the present invention comprises a digital camera, at least one light emitting diode (LED) light source, and at least one filter. In another embodiment, a system in accordance with the present invention comprises a digital camera, at least one light emitting diode (LED) light source, and at least one filter selected from a notch filter, a neutral density filter, or combinations thereof. Additionally, the system of the present invention can further include software designed to process, interpret and/or collect various data captured by the visual monitoring, or, imaging, system of the present invention.

Abstract: A hot wire welding process. An induction coil is used to preheat the filler metal wire prior to its entering the welding puddle/arc region. An induction coil is placed in close proximity to the welding arc. The filler wire is guided and supported by a delivery guide so that the filler wire passes through the center of, and is insulated from, the induction coil. The induction coil induces a current flow in the filler wire. The current produces heat as a result of the electrical resistivity of the filler wire. The heat produced raises the temperature of the filler wire just before it is fed into the weld arc region, thus reducing the energy required from the welding arc to melt the filler metal wire into the weld puddle.

Abstract: A method for fabricating a cable-in-conduit-conductor for use in superconductor application is described. The system utilizes a work surface with drum means provided at each end. A superconductor cable is fed from a supply source at one end. After the cable is pulled through a tube on the work surface, the leading edge of the cable is bent around one of the drums and returned to the opposite end of the table. This naked length of cable is once again bent around one of the drums and then pulled through another tube on the table. This process is repeated until an acceptable length of superconductor cable is present. Tension means are used in conjunction with a tube mill which compresses the tube-cable combination into a viable cable-in-conduit conductor (CICC). Notably, as this tension-compression is occurring, the naked lengths of cable are eliminated and each separate tube section is joined together to create a uniform CICC.

Abstract: A method of constructing a nozzle having cooling channels comprises a shell and a liner which are formed into a body of revolution having an axis of revolution. Helical welds are formed to hold the liner and shell to each other with a channel position being defined between each pair of helical welds. Pressurized fluid which may be a gas or a liquid, is introduced between the weld pairs to outwardly bulge the material of at least one of the liner and shell to define the channels.

Abstract: 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.

Abstract: A method and apparatus for building a workpiece of a desired geometry by deposit welding with a reusable preform. The reusable preform forms, supports, and cools the deposited molten weld material puddle while the weld material is solidifying thereby eliminating the need for a conventional preform. The reusable preform may be mobile or stationary in any shape, e.g., a block, a cylinder, or a belt. It is manufactured from either a combination of or exclusively of, a ceramic material or a material with high thermal conductivity.
