Abstract
Application of artificial long lines in arc welding equipment is considered. These lines allow forming pulsed welding currents of a regulated shape. The need for such currents is determined primarily by the objectives of pulsed technologies, where the loading current shape ensures the required time law of power input into the technological object. The most characteristic examples of such technologies are pulsed laser welding, laser heat hardening, laser piercing of holes, etc. The possibility of adjustment of amplitude-time parameters of loading current pulses in a broad range allows determination and further on ensuring the optimal parameters of pulsed electrophysical processes in order to improve their quality and productivity. Special pulsed current generators are required to create such energy flows, which are described and proposed in the paper. Ref. 12, Fig. 6.
Keywords: welding current formers, artificial long line, step-down multiphase converter, pilot-arc power source
