Abstract
The article discusses the results of research on the development of welding technology for Inconel 600 alloy. The aim of the research is to apply this technology to the production of retorts for gas nitriding furnaces, which must be resistant to aggressive chemical agents and the influence of high temperature. Studies that assess the impact of gas on the quality of the weld deposited on the samples. The research included the development of the initial welding technology, welding tests, observation and measurement of the padding weld face and fusion depth, as well as advanced tests of the microstructure of the pad welded layers. The highest fusion depth during padding was obtained in Ar + 2%O2 mixture. During the padding with a wire with a diameter of 1.2 mm, the metal sheet was fused through from a thickness of 3 mm. Slightly deeper fusion and a more favourable shape of the fusion surface were obtained by setting the handle at an angle of 80°. The most comparable conditions of padding in different gas shields were obtained with 50% Twin Pulse in the arc.
