In SL restoration and repair, we can create items without blueprints based on the actual object! Please contact us when you need our services.

This is an introduction to Kōei Techno System's "Restoration and Repair of Steam Locomotives," which focuses on the repair, regeneration, extension of life, and maintenance of parts, aiming for high quality, wear resistance, heat resistance, and anti-corrosion in machinery, similar to preventive medicine. Founded in 1946, we have a history of about 70 years and have introduced welding and thermal spraying technology early on in the internal combustion engine industry, primarily focusing on the repair (restoration) of engine parts. **Restoration and Repair of Steam Locomotives** We perform restoration and repair related to railways. In the restoration and repair of steam locomotives, we have manufactured items without blueprints through actual measurement. ■ Overall view of SL restoration and repair ⇒ Photo 1 ■ [Flange] Corrosion and wear part build-up welding processing ⇒ Photo 2 ■ [Piston] New casting production ⇒ Photo 3 ■ [Crosshead] New production ⇒ Photo 4 ■ [Rod] New creation ⇒ Photo 5 - [Heating pipe gathering] Corrosion part build-up welding processing - [Running gear parts] Wear part build-up welding processing - [Axle bearings] White metal build-up - [Firebox] Opening and closing hinge part damage welding processing - [Bracket (FC)] Breakage welding processing - [Coupling part] Wear part build-up processing *For more details, please download the catalog or contact us.*
