“In the realm of rail welding, we possess both the capability and expertise to manage large-scale projects. We’re renowned for delivering state-of-the-art welding solutions to the rail sector at competitive rates without compromising quality.” Karl Dean, Head of Welding
RSSI’s Rail Welding Division has been a frontrunner in providing specialised welding services to the rail and light rail sectors for many years. This legacy was further solidified after Carillion Welding’s acquisition by RSS Infrastructure in 2019. Strategically located in Doncaster and Tonbridge, we also have regional offices in Alnwick, Cwmbran, Romford, and Stoke-on-Trent.

The Expertise of Our Rail Welders

Our continuous employee training and development programmes show our commitment to excellence. We offer Level 1-3 Stressing Officer competency training. This investment in our team ensures that we can undertake and excel in large-scale rail welding projects with fully qualified professionals.

A Legacy of Rail Welding Excellence

Our Welding division boasts a stellar performance record, with a 99% first-time approval rate for our welds.

DC, Network Rail
Manchester Square One
Thank you for providing the S & T staff for Oakengates Tunnel at the weekend (and at short notice). I wish it were this simple every time! We will request your services again at the next exam. Thanks again; it was greatly appreciated.
PQ, Network Rail
Northampton
Karl and the team are superb. Always help us out last minute. Great on-call over the weekend. Really good staff, never any defects. Very happy and don't use anyone else.
CP, Network Rail
Holgate York
Your team worked together to complete installation of Xing and back rails. Then completed six welds. Great effort.
NR, Network Rail
Stoke on Trent/Stafford/Nuneaton
I can't fault the teams. They always help me and go above and beyond to do what they can. I only use RSS and have done for the last couple of years. Their work is spot on, and the welds are immaculate. The guys I deal with internally are smashing. I get on with them.
CF, Network Rail
Shrewsbury
Long-term staff from RSS, happy with them. We would like to see competencies of current staff so we can use their skillsets better. The only downside is a lack of flexibility—sometimes we need to change/cancel shifts.
JM, Network Rail
Saltley
I deal with Audrey a lot, who is wonderful. The quality of staff is very high. Had several members of staff on-site for around 18 months now. There are no issues, nothing to improve on, and I am very happy. Asked for further staff.
SP, Network Rail
Saltley/Sandwell
Communication has improved over the last few months. Works always delivered well, very few failures, impressed with staff sent.
DR, Network Rail Saltley
Saltley Depot
Worked with Karl for about 7 years. 264 welds with only 1 failure (welder error) is incredible. Staff at RSS always keen to understand if there is a failure and provide feedback to the welder. Cannot fault the team at all. We use RSS as our first choice due to the service. Karl and the team help me hit my internal KPIs.
DA, Network Rail
Manchester Guide Bridge
Really good service from the RSS Welding teams. I called James with a last-minute issue last week, and he sorted it out within 30 minutes. Always easy to get hold of and always sort out my issues. RSS are my preferred supplier. 10/10

GP, Midland Metro Alliance
Wednesbury
Deal with Christian and Steve a lot. Best of the three suppliers in terms of quality of staff - one in ten may turn out to not be the right fit, but that is life, and you don't always know until a few weeks into them being here. CVs are sent by Steve very quickly, and he provides all the info I could need. I am very happy with the quality of the candidates sent. Christian and Gav on-site always deal with PPE, toolbox talks, and the like. The staff like them.
CM, Network Rail Shrewsbury
Shrewsbury DU
Deal with Karl and James on a regular basis. Very knowledgeable in their work, always a good service, nothing to improve on, very happy.
MB, ISS
Cartbridge Lane
On Sunday night of week 11, I had three weld teams working on-site. The weather conditions were red hot one minute, then pouring rain the next. All the men worked brilliantly to pull around a job that, at one point, was falling behind schedule. One welder in particular was outstanding: NM. The most pleasing thing for me as a site manager, though, was the teamwork all six men showed.
DN, Network Rail

The team integrated well with the team, looking forward to working closely in the future.
