    摘要： A method and apparatus for welding or brazing of sheetmetal or plate covered with a temperature degradable protective coat, such as zinc or plastic. A cooling saddle supplied with liquid nitrogen is arranged on the side of the plate opposite that adjacent the welding torch. During the formation of the weld, gaseous nitrogen escapes through holes in the saddle to cool the protective coat and keep it from melting or volatilizing.

    摘要： A method for cooling a weld in steel piping during butt welding with cooling of the inside comprises, after joining of pipe ends by a root pass on the inside, cooling the junction being welded by subsequent passes with injection of a liquid medium at room temperature from the center of the pipe against the surrounding wall, in a direction between radial and tangential directions relative to the inner pipe surface. An apparatus for practicing the cooling method comprises a rotatable multi-nozzle assembly having a radius of rotation corresponding to the inside diameter of the pipe and is capable of injecting the cooling medium against the inner surface of the pipe, a duct for conducting the cooling medium to the nozzles, and a pumping device for forcing the cooling medium under pressure into the nozzles.

    摘要： Very large diameter metal shafts for turbines and electric generators, and other large structural metal parts, can be made in one piece to a high quality without occlusions, cavities, segregations, and cracks by building the part up layer by layer, each layer being formed by deposition of molten metal by welding along neighbouring tracks which together cover the area over which the layer is to be deposited. The weld deposition of the metal may be effected by a welding head which is moved longitudinally along the part, and if the part is simultaneously rotated the metal is deposited along a helical path in forming a layer. A plurality of welding heads may be used so that metal is deposited simultaneously at different positions during the construction of each layer.

    摘要： A burning table having a pan with a sloping bottom terminating in a clean-out trough. The water level in the table is controlled by over-flow pipes, one of which is valved to permit lowering the water level below the grating which catches the torch cut parts and the other of which controls the maximum water level necessary for burning but which is manually removable to permit complete draining of the pan and clean-out trough. A spray header extends along the pan opposite the clean-out trough and sprays water at high pressure through nozzles to wash debris resulting from the burning operation into the clean-out trough upon closing the valved over-flow pipe for filling the pan to the maxium water level necessary for burning. Bars for supporting the plate to be cut are mounted to minimize warpage and damage from the flame and to be readily replaceable.

    摘要： A magnetic clamping heat sink assembly is disclosed including a magnetic assembly with a carrier body including a magnet. A spring resiliently biases the carrier body. A base assembly includes a base plate. In a first operating condition, the base assembly of the magnetic clamping heat sink assembly is positioned in a first position away from a ferromagnetic element, and the spring holds the carrier body at a medial position spaced apart from the base plate. In a second operating condition, the base assembly of the magnetic clamping heat sink assembly is positioned in a second position adjacent to the ferromagnetic element, and the carrier body is driven downward against a force of the spring to a lower position and into contact with the base plate by magnetic attraction between the at least one magnet and the ferromagnetic element.
