BMZ accelerated locomotive frame welding 3 times thanks to new robot

Hybrid technology already provides processing of up to 24 bogie structures per month and helps expand production

At the Bryansk Machine-Building Plant (BMZ), the results of the robotic hybrid laser-arc welding complex, which was put into operation in December 2025, were summarized. In the first six months, the equipment confirmed its stated efficiency and significantly surpassed traditional technologies.

The productivity of the new complex increased by 2.7 times. The key advantage was the hybrid technology, which combines a welding arc and high-energy laser radiation. Thanks to this, a set of bogie frame beams is now manufactured in 4.5 hours instead of the previous 17 hours.

The new technology allowed BMZ to master the production of bogie frames for Novocherkassk Electric Locomotive Plant electric locomotives. Currently, the robotic complex processes 22 to 24 bogie frames per month.

After successful results, the enterprise began preparing documentation for the installation of a second similar complex. It is also planned to place it in the bogie shop to increase the volume of production for the Novocherkassk Electric Locomotive Plant.

The purchase of robotic complexes is being carried out within the framework of an investment project to create serial production of mainline diesel locomotives for trains weighing up to 7100 tons and shunting diesel locomotives with asynchronous drive and reduced fuel consumption. The project is being implemented using the Cluster Investment Platform mechanism with the support of the Russian Ministry of Industry and Trade and the Industrial Development Fund.
