Additive technologies (AT) or layered synthesis technologies are one of the most dynamically developing areas of “digital” production. A common problem of additive technologies is ensuring the proper microstructure of the synthesized material and the eliminating defects. The use of filler wire as a working material eliminates the problems associated with the low productivity of existing methods, the high cost of the equipment used, the limited types of materials used, due to the use of powder systems. Products made of stainless chromium-nickel steels are widely used in various industries. The main problem of additive technologies is to ensure the properties of the laminates are not lower than those obtained by traditional methods. Characteristic defects of laminated materials obtained by surfacing are increased porosity, non-metallic inclusions, a decrease in ductility, and for high-alloy steels, a loss of special properties. This predetermined the development of research in the field of additional technological measures to improve the final properties of the product. This paper presents the results of a study of the effect of ultrasonic vibrations on the structure and properties of the deposited steel 12Cr18Ni10Ti. For welding was used the wire 12Cr18Ni10Ti, process was carried out by plasma arc in a protective argon gas. It was found that ultrasonic treatment has an effect on the final grain size, structure formation and hardness, as well as on the geometry of the deposited layer. Studies show that the use of ultrasonic vibrations in the process of surfacing can be applied in the design of equipment for the implementation of processes of additive production.
