Today, the exhibition “Metalloobrabotka – 2025” opened in Moscow, in which the Polytechnic University is taking part. This is a traditional industry event, which for 40 years has regularly brought together the best specialists and largest companies from Russia, the CIS countries, the Middle and Far East and other regions of the world. The exhibition has been held in Moscow since 1984 and is recognized as the largest project in Russia and the CIS in the field of machine tool building. This year, over 1,200 companies are presenting advanced solutions for industry on an area of 50,000 sq. m. The number of participants is about 50,000 people.
“I am glad to welcome all participants of the International Exhibition “Metalloobrabotka – 2025″, one of the largest and most authoritative professional platforms in the field of machine tool building in Russia and the CIS countries. For all exhibitors, partners of the exhibition and guests of Expocentre, this is a unique opportunity to get acquainted with the most relevant industrial trends and advanced production technologies,” said SPbPU Rector Andrey Rudskoy. – At the end of 2024, the Government of the Russian Federation completed work on the formation of eight national projects of technological leadership, and the most important of them is dedicated to the industrial sector: the national project on means of production and automation, the main subjects of which are machine tool building in metalworking, technological equipment, additive technologies. These are the topics that are the focus of both the business program discussions and the key exhibits of the exhibition, in which Peter the Great St. Petersburg Polytechnic University, a traditional participant with many years of experience in developing and implementing high-tech technologies in various industries and acting as an executor of the main federal programs for technological development, is a traditional participant. I invite all colleagues to a dialogue on the thematic tracks of the exhibition and to further productive cooperation.”
The main topics of the 25th anniversary exhibition are innovations in machine tool building, automated production lines, modern tools and materials. The focus is also on digital solutions: software for production management, robotic systems, artificial intelligence technologies. The business program of the exhibition will be focused on applied tasks of industry and issues of strategic development.
“It is a great honor for us to be part of this forum, where traditions and innovations of the industry meet. Our institute has been a flagship in the field of mechanical engineering and materials science for many years. We actively develop metalworking technologies, introducing modern solutions in turning, milling and casting processes. Our developments are successfully used at enterprises of the aerospace, automotive and energy industries, ensuring high precision and reliability of products, – noted the director of the Institute of Mechanical Engineering, Materials and Transport of SPbPU Anatoly Popovich. – We pay special attention to additive technologies, which open up new horizons for industry. Together with industrial partners, we create unique methods of 3D printing of metal components, reducing production times and reducing resource costs. It is important that we not only improve technologies, but also train personnel capable of working at the intersection of disciplines. Our students and researchers are actively involved in projects that combine classical metalworking and digital innovations. I am confident that the exhibition will become a platform for fruitful dialogue, and the synergy of experience and new ideas will help us move the industry forward together.”
SPbPU will demonstrate not just scientific developments, but technological solutions ready for implementation. This year, our university will present a wide range of advanced developments in key areas of modern production – from 3D metal printing to robotic welding and the creation of intelligent materials.
Additive manufacturing
Polytechnic University takes metal 3D printing to a new level: from developing heat-resistant nickel powders to laser synthesis of critically loaded components. The university has more than ten domestic SLP printers with a multi-laser system, which allows creating complex parts for gas turbines and aviation. Thus, the VPLS “Mercury” installation developed by SPbPU jointly with ZAO “Biograd” allows printing gas turbine components from heat-resistant nickel alloys at a heating temperature of up to 1300 degrees Celsius. A powerful laser (1000 W) and precise control of the material structure provide high performance. This is no longer a prototype – it is a response to import substitution in aerospace and energy. In addition, multi-material synthesis, plasma and flame spraying technologies have been implemented. They print not only with alloys – SPbPU has piezoceramics, carbide ceramics, and high-entropy composites in its arsenal. All this is in the interests of import independence and accelerated implementation in real production.
The Polytechnic University is also equipped with stationary and mobile technological complexes for direct laser deposition, laser cladding, laser and hybrid laser-arc welding of thick metals, and laser welding of thin metals (up to 100 microns).
Electric Arc Growing (WAAM)
SPbPU offers a full cycle of WAAM implementation — from design to integration into production processes. The technology of layer-by-layer wire surfacing using an electric arc is used to create large-sized and complex-shaped products from titanium, steel, aluminum and other metals. Robotic complexes are adapted to the tasks of specific customers, providing up to 6 kg/h of printing and full automation. The robotic complex (RC) for additive electric arc growing is a robotic cell that has everything necessary for electric arc growing. In addition, the Polytechnic University supplies the systems with its own software that allows monitoring the status of the manipulator and peripheral equipment, as well as generating control programs for the implementation of the electric arc growing technology. Unique examples: gas turbine engine impellers and wheel rims, which have passed strength tests and demonstrated competitiveness compared to cast products.
Design and manufacture of laser technological complexes
Polytechnic University develops turnkey laser systems — from foil welding to repair and manufacturing of components for power and mining equipment. The arsenal includes robotic laser cladding systems, mobile units, robotic systems with 5-kW lasers, direct laser deposition with powders and wire, as well as hybrid systems with an inert atmosphere. Using a robotic laser welding system for thin metals (up to 100 microns), serial welding of fuel elements of a hydrogen energy source for Russia’s first passenger ship, Ecobalt, was implemented.
The university developed a technology for surfacing a porous coating with a thickness of 600 microns with an open porosity of 60-80% and the ability to control these parameters. The cups successfully passed preliminary clinical tests for integration and toxicity of the surfacing layer with bone material.
Repair of power equipment components was carried out: nozzle and working blades Man Turbo, SGT-700, TV 3-117, VP2500, VPT-50-2, Man Turbo, MARS100, Taurus 60, Man Turbo, MS5002E, TV 3-117, NK-12ST, DR59L, GPA GTK-10I, MS3142J.
As part of cooperation with the company JSC UK KER-Holding, the Polytechnicians created and delivered a technological complex for direct laser growth.
Together with TsNIITMASH, a demonstration separation module of a power plant was created using direct laser growth. The result is a reduction in the number of welding operations, an increase in anti-corrosion properties and reliability in extreme Arctic conditions. The university is conducting projects with Rosatom, Gazprom and other industrial giants, offering customers not just equipment, but fully adapted technological solutions.
Friction stir welding (FSW)
SPbPU is one of the few in the country that uses STP and TSTP on a large scale: both in spot and seam configurations. This is a solid-phase welding technology that does not involve melting, but has high strength, minimal deformations, and the ability to weld even dissimilar materials — aluminum with copper, composites with metals. The university produces seams up to 8 meters long, develops its own equipment, and trains customer personnel. The use of STP is relevant for aviation, shipbuilding, energy, and military equipment — wherever precision and durability are important.
We invite you to the Polytechnic stand 1A25, where you can see and evaluate the latest technologies and innovations from SPbPU in the field of metalworking.
