A review of studies, devoted to the processes of nonconsumable electrode inert-gas welding with welding current modulation was performed. The second part of the review is devoted to analysis of the works, dealing with the features of metal penetration (aluminium alloys, stainless steels, high-temperature nickel-chromium alloys) and weld formation in TIG welding with modulated current. 12 Ref., 16 Tables, 19 Figures.
Keywords: arc with refractory cathode, TIG welding, metal being welded, penetration, weld, welding current modulation, pulse, frequency, fill factor, amplitude
