Friction Stir Welding, Accessible for You

We simplify Friction Stir Welding combining expert engineering and advanced FSW systems to take your concept from prototype to production.

Advanced manufacturing should be accessible, not complex. Friction Stir Welding (FSW) offers unmatched strength, precision, and reliability, but getting started is often a challenge.

Simplifying Friction Stir Welding — so you can focus on innovation, not limitations.

What is Friction Stir Welding?

Friction Stir Welding (FSW) is a clean, solid-state welding process for joining metals. Perfect for lightweight, high-performance designs. It works well with all aluminium alloys as well as copper, steel, titanium and dissimilar metals.

Unlike traditional welding, FSW doesn’t melt the material. Instead, a rotating tool stirs the metals together, producing strong, low-distortion joints with no porosity or cracking.

What does FSW make Possible?

Why StirLight?

StirLight exists to make high-integrity friction stir welding accessible, fast, and effective.

Flexible Collaboration

From funded R&D to fast-turnaround production, we work the way you need: agile, responsive, and deeply technical.

From R&D to Production

We support your journey from process development and tooling to short-run and pilot-scale manufacturing.

UK-Based, Globally Connected

We work with innovators across the UK and Europe to bring real-world FSW solutions to market.

Engineer-Led

Our team solves real welding problems for complex materials (not just selling tech for its own sake).
