摘要： The proposed method relates to the ionization of plasma-generating gas in ailot arc before being supplied to the electrode region, thus generating charges in this electrode region, the charges promoting dispersion of an arc spot. For this purpose, an electrode assembly is provided within the plasma-arc torch, which electrode assembly comprises a hollow tungsten electrode and a solid electrode of the same metal, the solid electrode being radially spaced from the hollow electrode. Both electrodes are put in an electric power circuit, whereby an arc is initiated between the electrodes when switching on the electric circuit, plasma being generated in the arc, which plasma serves to start the main arc and provides for dispersion of the arc spot over the surface of the hollow electrode. This decreases the current density in the arc spots and, hence, minimizes electrode erosion. Such an arrangement provides for the nozzle to be electrically insulated from the electrodes and, therefore, protected against harmful damage.
摘要翻译：所提出的方法涉及在被提供给电极区域之前的导电电弧中的等离子体产生气体的电离，从而在该电极区域中产生电荷，促进电弧斑点的分散。为此，在等离子体电弧炬内设置电极组件，该电极组件包括中空钨电极和相同金属的固体电极，固体电极与中空电极径向间隔开。两个电极都放在电源电路中，由此在接通电路时在电极之间引发电弧，在电弧中产生等离子体，该等离子体用于启动主电弧，并提供电弧点在中空电极的表面。这降低了电弧点中的电流密度，从而使电极腐蚀最小化。这种布置使得喷嘴与电极电绝缘，并因此防止有害损坏。

摘要： Shapes with circular corrugations are produced by spinning a sheet metal blank under the action of oppositely directed deforming and backing forces. The blank is given the configuration of an envelope of revolution with a continuously diverging flare and is secured at the end nearest to the geometrical apex of the flare, and the circular corrugations are formed sequentially from the smaller towards the larger diameter by applying a concentrated deforming force to the inside surface of the blank, the deforming force being directed along the blank axis.

摘要： A welder arranged inside pipes to be welded comprises a housing with the longitudinal axis thereof matched with the axis of the pipes. On the housing are a welding transformer and two mechanisms clamping the pipes, each having a drive moving the mechanism along the axis of the housing, and each being electrically connected to the transformer. The housing has mounted thereon a pipe flashing and upsetting mechanism with its own hydraulic drive, kinematically coupled to one of the pipe clamping mechanisms, a hydraulic pump supplying fluid to the drives, and a mechanism driving the welder along the pipes' axis. The housing carries two bearing discs secured at opposite ends and three clips mounted on roller supports and movable along the housing's axis. Two clips are incorporated in the first and second clamping mechanisms, respectively, and the third is part of the flashing and upsetting mechanism. The clip incorporated in the first pipe clamping mechanism is interposed between the bearing disc and the clip of the second clamping mechanism and is coupled to the bearing disc by means of its hydraulic drive. Another kinematic coupling is between this clip and the bearing disc. The clip of the flashing and upsetting mechanism is close to the second bearing disc and coupled thereto by its own hydraulic drive. The clip of the second clamping mechanism is interposed between the clip of the first clamping mechanism and that of the flashing and upsetting mechanism and is coupled to the clip of the flashing and upsetting mechanism by its hydraulic drive; and an additional kinematic coupling is between the clip of the second clamping mechanism and said clip of the flashing and upsetting mechanism.
