SSPA of Powder Metallurgy offers customers friction stir welding technology, including the development and provision of working tools under a commercial agreement with technical assistance and the delivery and/or modernization of existing equipment to the customer, as well as the performance of welding of parts and assemblies agreed with the customer under a manufacturing agreement.

Application of Friction Stir Welding (FSW) – one of the most promising energy- and resource-saving technological processes in the field of welding and related technologies.

Many years of experience in industrial application of FSW have shown that this type of welding is not inferior to traditional types of welding and can be used in many areas of mechanical engineering.

Developer and manufacturer - «Institute of Welding and Protective Coatings» (Minsk), (in Russian) of the "O. V. Roman Institute of Powder Metallurgy ".

Scope of application - enterprises and organizations of mechanical engineering, energy, petrochemistry, construction, agriculture and other industries.

It is possible to design technological processes and manufacture welded structures by the FSW method using the developed equipment in the Republic of Belarus, as well as for export to the Russian Federation, the CIS countries and Eastern Europe.

Information is posted in the Album of promising developments of organizations of the National Academy of Sciences of Belarus for the real sector of the economy (2023) (in Russian), p. 132-133.

The FSW process corresponds to world analogues and allows free competition with the best developers and manufacturers of similar products.

Advantages: absence of hot, cold cracks and pore formation in the joint; FSW of thin-sheet materials with a thickness of 0.1 mm.

The economic efficiency of using FSW in industry instead of the fusion welding methods used today is achieved due to the process indicators for which energy consumption is 2-5 times less (2.5% of the energy consumed in laser welding, 10% of the energy consumed in arc welding), the production cycle is 50-75% shorter, the cost of 1 running meter of seam is 4-10 or more times lower. No filler materials and protective materials (gases, fluxes, wires, etc.) are required.

This welding method is more harmless in comparison with traditional fusion welding methods. With FSW, there is no harmful radiation from the welding arc, no release of metal vapors and strong heating (liquid phase) of the metal. At the same time, FSW is ecologically and hygienically safe, does not require the use of individual means of protection for the welder and costs for general exchange ventilation, etc.

The absence of hot, cold cracks and pore formation in the joint allows the process to be carried out with low heat input, which, in turn, leads to insignificant grain growth in the heat-affected zone, small residual deformations and stresses, as well as less softening during welding of heat-strengthened aluminum alloys and other alloys, makes it possible to weld difficult-to-weld materials, including in various combinations.

The use of the FSW process in production will reduce the costs of training qualified welders, since this welding process can be performed by a milling machine operator who can perform preparatory and post-weld mechanical processing of the product and carry out the welding process itself on one equipment.

The development at the enterprise is protected as a commercial secret.
