OTT FLASH BUTT WELDER

Built on Pride.

Delivered with Precision.

At On Track Technicians, the railway isn’t just what we do — it’s who we are. With a heritage rooted in generations of railway workers, we’ve grown from a family-run team into one of the most trusted names in UK and Irish rail infrastructure.

Now, we’re proud to take a bold step forward — welcoming our first Flash Butt Welder, a state-of-the-art machine from Geismar, fully branded in OTT colours. It’s more than a machine — it’s a symbol of how far we’ve come.

We’ve invested in the best so we can offer safer tracks, smarter solutions, and a smoother future.

What is Flash Butt Welding?

Flash Butt Welding fuses rail ends by generating heat through electrical resistance, followed by precision forging. The result? A single, seamless rail with exceptional strength.

It’s clean. It’s fast. It’s the gold standard in rail welding.

Why It Matters

Our welds are tough — like the team behind them.
- No added materials. Just steel forged into one.
- Less risk of failure. More trust in every welded joint.
Higher quality welds means less defects which results in smoother travel — whether you’re moving freight or people.
Faster weld times mean we can maximise productivity in short possessions.
We understand the importance of getting it done — and done right.
No added material, Less waste. Zero waste to landfill. More sustainable railways.
