    Abstract: A welding complex in accordance with the invention comprises a machine for resistance butt welding, means for supporting the end part of the pipeline and holding means including a platform reciprocable axially of the pipeline and a plate with a device for carrying the pipe section to be welded, rotatable by a drive between the positions of loading a pipe section and aligning it with the pipeline. For loading the holding means with the plate rotated into the loading position, by longitudinally displacing a pipe section from the accumulator, the latter is arranged alongside the platform, so that the pipe section it delivers extends at an acute angle relative to the end of the pipeline.

    Abstract: A pipe resistance butt welding apparatus disposable within the pipes to be welded comprises a fixed expanding clamp and a movable expanding clamp, provided with clamping elements and actuating cylinders and intended to fix the pipes to be welded with respect to the apparatus. A cylinder to effect an axial movement of the movable expanding clamp is installed at the end at which this expanding clamp is located; the axial movement provides for drawing together the ends of the pipes to be welded in the course of fusion and upsetting. The cylinder for the axial movement of the movable expanding clamp is coupled with the actuating cylinder of the same clamp and with the clamping elements. The devices making up the apparatus and the cylinders are coaxially installed within a body wherefrom the clamp elements extend outwardly to engage the inner surface of the pipes being welded. Modifications of the apparatus for weld-joining of medium and large diameter pipes respectively are also described.

    Abstract: The doughnut-type transformer comprises a spirally wound core consisting of several individual annular cores each tightened by rod members. The annular core is surrounded by transformer sections comprising the primary and the secondary windings. Each winding is composed of turns shaped as sectors in the plane of the transformer cross-section, a cooled turn of the secondary winding being placed between the turns of the primary winding in each transformer section. The turns of the windings surround the annular core so that the geometric center of each winding is displaced from the geometric center of the annular core in the cross-sectional plane thereof and the geometric center of the annular core is farther from the transformer axis. Each turn of the secondary winding is provided with a passage for cooling water to circulate therethrough, which water being supplied and discharged through one and the same contact ring and is first cooling one half of the whole number of the transformer sections and then the other half.
