Welding is part of the foundations of the business. Our experienced teams can write, implement, test, and assess procedures - and do so worldwide.


A complete
welding service

Our rail welding division meets the demands and needs of railway contractors and Network Rail in the delivery of national rail projects using the aluminothermic and manual metal arc welding processes.



Welding is part of SWGR’s heritage, and as such, we can write, test, implement and assess welding procedures – supplying teams on rail projects nationwide. This makes SWGR one of the only welding providers in the UK to provide all aspects of welding – passing cost savings and efficiencies on to the customer.

Find out how we’re going the extra mile to keep everyone Safe Together.

The experience you need

We carry out both routine, remedial welding jobs and welds as part of more complex engineering projects, and have a great deal of experience working on operational sites, so we can ensure that our services are only ever a huge help to any project.


We provide a national resource that supplies welding teams and services across the UK. Our wholly owned equipment is subjected to stringent maintenance and inspection regimes and all of our welding teams carry the requisite safety and skills certification.


Our solutions include:

  • Head Wash Repair (HRW) : A cost-effective solution
    to repairing railhead defects and significantly decreasing track
    maintenance costs. The fault is ‘scooped’ out by burning.
  • Manual Metal Arc (MMA) : Repairs to plain rail –
    all rail grade groups and welding for track circuit purposes and also
    covers repairs for all S&C. Faults are removed by grinding.
  • Aluminothermic Welding : Molten steel is poured
    into a pre-heated mould surrounding the gap between rail ends to be
    joined – the metal then fills the moulds and the slag is separated.

“Welding was the foundations that this business was built on. We’re proud to have provided essential welding services for more than 30 years that have made tangible differences in the longevity of some of the UK’s most complex infrastructure.”

Raymond Johnstone, Head of ScotWeld, SIS and ScotTrain
