“…Research on the metallurgical properties, wear process and fatigue of Inconel 625 weld claddings was carried out by the authors Sandhua & Shahi [27]. The Inconel 625 laser wire cladding technology for corrosion protection was optimized in their work by the team of authors Hu et al [37] while the study of the substrate material on which Inconel is plated with the help of selected technological methods was investigated by the author Sotoodeh [32]. On the basis of the analysis of the literature sources carried out by the authors who have dealt with the issue in their studies, it can be said that the collective of authors of this, as well as their previous articles [11,25], which is followed by the acoustic study of the authors obtains a comprehensive overview of problematics and in their experiments presented in this research brings new results that will expand not only theoretical, but also practical knowledge and possibilities of CMT method of welding Inconel material on the base material 16Mo3, which brings new possibilities in the production of bimetallic pipes.…”

Research carried out by the authors of this paper is focused on the technological process of Inconel 625 welding with the MAG - CMT method. Inconel 625 was welded on the substrate material, which was 16Mo3 steel. Both materials are used to produce so-called bimetallic tubes, which in practice serve as part of the equipment intended for waste incineration. For this reason, the bimetallic tubes have to withstand extreme conditions during their operation. Therefore, bimetal pipes are highly stressed composite components that must resist corrosion in a chemically aggressive environment. For this reason, an extensive material and technological analysis of the production of pipe bends with a supercritical bend of 0.7D from bimetal pipes with Inconel 625 cladding was performed. In the welding process, the authors investigated the possibilities of the CMT method with and without divergence. The most important factor in deciding which method would be appropriate was to measure the amount of iron on the surface of the coating layer. The authors' paper builds on the authors' previous research in this area, which was mainly focused on research on critical bending of bimetallic tubes.
