Abstract

This paper deals with the issue of welding two different materials – titanium and stainless steel (UNS N50400 + X5CrNi 18-10). These two materials have completely different chemical compositions and mechanical properties; therefore, process of their mutual welding is complicated. Melting temperature of both materials is also different. An innovative MIG LSC arc welding method with an additional material has been selected for this purpose. A protective atmosphere was used in order to avoid galvanic corrosion of materials that would preclude the welding process. Aforementioned atmosphere contained 100% Ar. The MIG LSC welding method was designed by Fronius. Presented experiment compares utilization of following 4 different electrodes (additional material) for the welding of titanium and stainless steel: Ti, Fe, corrosion-resistant Fe and CuSi3 electrode. Tensile test was utilized for evaluation of weldment mechanical properties. Measured results were supplemented with a metallographic analysis snapshot and tensile diagram.
