The paper presents the promising directions and obtained results in the fields of welding and related technologies, pursued in Belarus at SSPA «Powder Metallurgy», including friction stir welding, additive technologies, flame spraying of powder materials and electrospark coating. Comprehensive development of works in the field of additive technologies is achieved by application of equipment, which ensures polymer and metal 3D-printing, production of metal powders and additional compaction operations. Alongside research performance, this equipment is used for product manufacturing. A unit with a system of recording the welding mode parameters was developed for conducting experimental studies and practical application of friction stir welding. Computer modeling programs (Deform, Sysweld, Ansys, etc.) are used during performance of investigations and development of technological processes and tool designs. Tool manufacture is performed in experimental production, in particular by the methods of powder metallurgy and additive technologies. New scientific and practical results were obtained on development of processes and equipment for flame deposition of coatings from powder materials on parts of various functional purposes, using high power jets (up to 125 kW). Investigations were performed and equipment was developed for forming thick-layer (up to 5000 – 7000 μm) electrospark coatings with application of electrode-anode vibration of 22 kHz frequency. 18 Ref., 8 Fig.
Keywords: friction stir welding, additive technologies, flame spraying, computer modeling, tool manufacture, equipment for electrospark coating deposition
