Abstract
The paper gives the results of studying the developed two-loop system for automatic stabilization of average values of arc voltage and welding current in consumable-electrode pulsed-arc welding by regulation of the parameters of the power source pulses and electrode wire feed rate, respectively. Separate and combined influence of the disturbing production factors (change of electrode extension, lowering of mains voltage) on the process of consumable-electrode pulsed-arc welding of low-alloyed steels and quality of weld metal has been studied
Keywords: consumable-electrode pulsed-arc welding, disturbing factors, carbon structural steels, process stabilization, average values of arc voltage, average values of welding current, feedbacks, mode parameters, weld quality
