The article presents the principles of direct metal deposition process, types of technological equipment and materials for implementation. The samples of deposited products have been demonstrated.

The article presents the results of investigation the technological opportunity of laser-TIG welding of titanium alloys. The experimental stand for implementation of process with the capability to feed a filler wire was made. The research of the nature of transfer the filler wire into the welding pool has been demonstrated. The influence of distance between the electrode and the surface of the welded plates on the stability of the arc was shown. The relationship between welding velocity, the position of focal plane of the laser beam and the stability of penetration of plates was determined.

The article presents the results of a research of the process of laser hardening of steel 14Cr17Ni2 (AISI 431) by radiation of a high-power fiber laser LS-16. Assessment of the theoretically possible maximum depth in laser processing without additional beam transformations, the use of additional coatings and devices were shown. The results of experiments on increasing the depth of the hardened layer during laser processing by using scanning of the laser beam and optimally selected mode parameters without scanning are demonstrated. The influence of the number of passes on the depth of the hardened layer is investigated. The microstructure of hardened samples was studied and quantitative estimation of structural components was carried out. The microhardness of hardened samples at different modes of laser hardening was measured.

The paper presents the results of an investigation of application arc, laser and laser-arc sources for process direct deposition of aluminum wire. Experimental studies have focused on the determination mode of parameters to provide uniform formation of a thin wall during successive layering. The metallographic analysis of cross-sections of the samples was performed. The microhardness, chemical and mechanical tests were carried out.

Choosing the right strategy for further technological development and priority market segments are an important aspect for companies developing in the high-tech process market. The development of innovative is impossible without the information exchange and cooperation between the countries. Most of the companies in this market have limited resources. This requires a high rate of return on investment and appropriate protection. It is necessary to estimate the current level and to find out what contributes to the accumulation of knowledge and scientific information to reach the next stage of development. Such an assessment can be made on the basis of the collected data. Statistical indicators qualitatively and quantitatively characterize additive production. The article provides an analysis of current trends and statistical indicators that characterize international cooperation in the field of innovative processes, including additive technologies. The main channels of the transfer of these technologies are listed, and the structural associations responsible for the development and dissemination of knowledge are indicated. The dynamics of changes in the volume of state budget allocations for research and development work per scientist for leading European countries is analyzed. The dependence of the increase in the publication activity on the change in the ratio of the number of researchers per million people of the population for different countries is demonstrated. The leading countries in generating revenue from trade in equipment and technologies in the field of additive manufacturing and a country having the largest number of the patents in this field are identified.

The article presents the results of the analysis of patent documentation on laser additive manufacturing registered in the territory of the Russian Federation. As a result of the research, the dynamics of patent activity is determined, the top patent holders, the leading countries in the considered technological field are identified, the top of inventors is compiled, the main technological segments for application of patented solutions from the field of laser additive manufacturing are identified.
