SYNERGISTIC WELD THROTTLE Russian patent published in 1995 - IPC

FIELD: welding. SUBSTANCE: throttle shapes the pattern of the current curve, optimum with respect to the technological properties, realizing the corresponding programs of optimization during the cycle and the order of its interchange in the process of welding depending on the active disturbances. In the weld throttle having the core of armored- or rod-type with a gap, the power winding on the bar is included in series into the welding chain. The core is made of two or more packets of armored-or rod-type, correspondingly, with a connector in the transverse plane of the bars. In this case parts of the core are mounted with gaps which are filled with nonmagnetic material. The height of the gaps in the packets is different, the middle lines of all the gaps coincide. EFFECT: enhanced efficiency of the mechanized arc welding. 3 cl, 3 dwg
