Welding

We’re always seeking ways we can apply our knowledge to support our customers. Tapping into our extensive welding expertise, our welding technology services provide innovative, high quality solutions to help you improve weld integrity and extend rail life.

Flash butt welding
Flash butt welding is currently the highest quality method for joining rails that is commercially available. British Steel adopted this method for welding its rails several decades ago. As a result, we have built a wealth of experience of both depot-based and mobile flash butt welding.

British Steel owns and operates depot welding facilities - supplying mainline railways with high quality welds that are a prerequisite of safe and efficient networks. We have led the way for many years in developing welding expertise. We assist network owners and weld plant operators around the globe with our knowledge, expertise and unique testing facilities. You can rely on us to help you with:

  • Fault-finding
  • Development and approval of weld plant and processes

Gauge corner restoration
We have developed a patented weld repair process. This low pre-heat process is ideal for rebuilding worn grooved rail in track to:

  • Extend rail life
  • Reduce life cycle costs


A welding technique requiring low pre-heating offers significant advantages:

  • It avoids damage to polymers surrounding the embedded rail
  • Unlike ‘no-preheat’ methods of weld restoration, it produces robust, crack-free weld deposits

The prescribed low pre-heat of between 60°C–80°C ensures the development of a tougher microstructure that is resistant to cracking. Restoration of our ML330 rail grade using this process has been evaluated by the University of Cambridge. The results validate the principles of the welding process and the integrity of the welds carried out on ML330.

Our weld restoration process is now being successfully employed to restore grooved rail in tramway networks throughout Europe. We offer advice and consultancy to tramway networks over a wide range of rail welding issues. By sharing our expertise, we can help customers reduce the life cycle costs of renewal and maintenance.


Welding services
Our Rail Technologies and Research & Development teams can help you to reduce weld maintenance costs and extend rail life. We offer expert advice on:

  • Flash butt welding
  • Aluminothermic welding
  • Repair welding


We can develop welding schedules designed to control weld geometry, optimise weld process control and enhance process monitoring and analysis. Utilising extensive experience in both the practical aspects and theoretical metallurgy of welding, we have helped customers to:

  • Demonstrate compliance to international standards
  • Improve static and mobile welding systems
  • Deliver significant cost and time savings on repair welding processes


Our state-of-the-art laboratory facilities can provide fatigue and bend test services, to help optimise your welding equipment performance and processing. We can develop manual metal arc and other discrete defect repair procedures. We can also offer advice on options available for aluminothermic welding.
