Influence of Protective Gas Content on Quality of Welded Joint While Welding With Impulse Supply of Electrode Wire

[摘要] Currently one of the advanced ways of obtaining quality welded joint while welding of medium alloy martensitic-bainitic steel is the one with impulse supply of electrode wire in gas mixture Ar(70%3%)+C02(30%3%). Results of experimental studies proved that application of protective gas Ar(70%3%)+C02(30%3%) in comparison with CO2(100%) enables to increase strength properties of the welded joint by 10-15% and enlarge the transition coefficient of chemical elements.
