Works devoted to the processes of inert-gas nonconsumable electrode welding with current modulation were reviewed. In the first part of the review attention is focused on studies, dealing with the features of running of thermal, gas-dynamic and electromagnetic processes in nonstationary arcs with refractory cathode at different modes of arc current modulation. 35 Ref., 2 Tables, 18 Figures.
Keywords: arc with refractory cathode, arc plasma, TIG welding, welding current modulation, pulse, frequency, fill factor, amplitude
