Results of analysis and modeling of frequency characteristics of welding circuit in pulsed-arc welding processes are given. Three different approaches to implementation of these processes are considered, namely through modulation of output voltage of the welding current source, exciting torch vibrations, and pulsed feed of electrode wire. It is shown that the working range of welding current pulses strongly depends on the approach employed
