STP RUZKHIMMASH Sespel friction stir welding system with a vacuum table

Developed and manufactured by Cheboksary Enterprise Sespel CJSC, the system performs two key operations: edge milling and friction stir welding of aluminium panels. These panels form the basis of aluminium railway carriage bodies.

Integrating milling and welding in a single machine ensures precise, consistent joints, improving the strength, leak-tightness and durability of finished products. This is particularly important for transport structures exposed to varied operating loads.

Aluminium alloy bodies significantly reduce carriage weight, increasing payload capacity and improving energy efficiency. This makes railway transport more environmentally friendly and economical.

The system demonstrates Sespel’s technological capabilities and engineering expertise in developing and manufacturing modern transport engineering equipment.

This equipment opens up new opportunities for automation and improved railway carriage manufacturing quality, making Sespel a reliable partner for businesses focused on innovation and high standards.
