...Low-oxidizing Ar-based mixtures cannot be considered as general purpose shielding gases for welding of carbon and low-alloy steels in terms of Ukrainian industry, since the most widespread in our country wires Sv-08G2S and Sv-08GS have higher level of alloying in comparison with wires of similar designation (SG-1, SG-2, SG-3, DIN 8559) applied in Europe....

...Since consumable-electrode gas-shielded welding process dominates in Europe, the main attention is paid to the problem of selection of shielding gas composition....

...Besides, European welding production uses small diameter wires and milder welding modes in comparison with that used in Ukraine....

...Rigid limitation on composition of the shielding medium, provided by technological recommendations of TIME-process developers [23, 33], have no grounds since similar indices of efficiency and quality can be received using cheaper and simpler in production Ar-based mixtures without helium, for example, Ar + CO2 + O2, and by thorough selection and correction of the mode parameters [11, 14, 34]....

...There are also high-productive methods such as Rapid Arc and Rapid Melt [10, 11, 32] which are carried out in shielding mixtures with helium (vol....
