Preparing integrated joints of titanium alloys with steels (A review)

The analysis of welding processes of titanium alloys with steels is presented. There are such research directions: the use of prefabricated bimetallic transition elements (welded by tra­ditional methods); minimization of energy and heat in the weld area of metals; the use of methods of welding metallurgical engineering. The advances in welding technology have led to innovative solutions such as friction welding with stirring, as well as the use of liquid-phase layers and 3D printing of nanostructured layers at the welded edges to acce­lerate diffusion processes in diffusion welding. The new methods in welding metallurgical engineering increase the efficiency of Ti–Fe compounds due to the use of multilayer com­positions of tantalum or niobium from the side of titanium and bronze – from the side of steel, and also vanadium inserts and its alloys, for example, alloyed with tungsten or chro­mium. The urgency of further development of standards for support and dissemination of industrial technologies for welding of Ti–Fe joints, training and preparation of technical staff for the implementation of these technologies is noted.
