A centralized point for release of welding consumables has been successfully commissioned and is operating as scheduled at the Leningrad NPP-2 construction site.
The new system implemented by the PJSC SUS Chief Welder Office has made it possible to ensure full quality control, enhance accounting for consumables usage and increase work productivity.
The project was launched in a test mode in June 2025, and has been in full operation since July.
Stanislav Antonov, PJSC SUS Chief Welder:
“The introduction of centralized release of welding consumables has become a pilot centralization project in our company. The implemented system has already proven its high efficiency, and we plan to apply this experience to other construction sites in the near future”.
Timur Karimov, Head of the Welding Equipment and Materials Department at PJSC SUS:
“We have launched the project on centralized release of welding consumables to improve the quality of welding work and strengthen control over material consumption at the LNPP-2 construction site. Previously, electrodes were stored and distributed in a decentralized manner, that is in each construction and installation department or on each site. This did not guarantee either their proper preparation or cost control. Now we have achieved full transparency in the use of materials. Each department prepares an application and submits it to us. Based on the aggregated data, we prepare a batch of materials for release. For welders, that is first and foremost convenient and fast, as they receive already prepared materials along with containers. This simplifies the process and significantly reduces the turnaround time”.
The introduction of the centralized release point has ensured full traceability of welding consumables - now, each application is linked to a specific project and welder. Electrodes undergo mandatory thermal treatment (calcination) in accordance with regulatory documentation and are handed out in special containers. Strict accounting and control have been introduced, unused materials are returned at the end of the shift, then re-prepared and re-introduced into circulation. The use of non-design materials is excluded, which increases the reliability and safety of welded joints. The main result is that the time for receiving materials has been reduced: after undergoing morning safety briefing and receiving the smartwatch, welders go to the work equipment release point, give their last name and receive everything they need — quickly, properly and against signature.
Klim Trishkin, welder at Construction and Installation Department 16 at PJSC SUS:
“The release of electrodes and containers is conveniently organized at the construction site - everything is in one place, and every welder knows where it is. Every morning after the safety briefing, all welders come to the equipment release point, receive the required number of electrodes and containers, and also sign for the consumables received. Everyone gets exactly as much equipment as they need for a shift and goes straight to their workplace”.
The equipment release point is located next to Checkpoint 3 in a specially equipped room divided into a storage area with a weekly supply of electrodes and a heat treatment area. The average daily consumables output amounts up to 60-80 kg, depending on the number of welders involved, which is an average of 25-40 people per shift.
The electrodes release point remains the first centralization project. In the future, the site will provide not only welding materials and equipment, but also other consumables. A single-release point of tools, hardware, paints and other materials will be organized here in the long run.
