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 steel, high-temperature nickel-chromium alloys) and weld formation in TIG welding with modulated current. 12 Ref., 16 Tabl., 19 Fig.
Keywords: arc with refractory cathode, TIG welding, welded metal, penetration, weld, welding current modulation, pulse, frequency, fill factor, amplitude
