Why Aluminium TIG Weld Quality Matters

When you’re upgrading a performance car, it’s easy to focus on horsepower, suspension, or tuning. But one detail that often gets overlooked is weld quality — especially on aluminium tanks like header tanks, catch cans, and reservoirs.

Strength You Can Trust

Poor welds aren’t just cosmetic. In a hot engine bay, tanks are under constant stress from heat, vibration, and pressure. A weak joint can crack or leak, leading to overheating or even engine failure. TIG (Tungsten Inert Gas) welding creates strong, clean joints that last under the toughest conditions.

Clean, Professional Finish

TIG welding gives a precise, uniform weld bead. It’s not only stronger, it looks better too — and in motorsport builds, appearance matters. A neat, consistent weld shows the part has been built with real care and attention.

Built for Motorsport — Backed by Aerospace Standards

There’s a reason top motorsport fabricators use TIG welding for critical aluminium parts. It’s the only process that delivers both strength and reliability. At The Alloy Shed, that quality mindset comes from an aerospace background — experience welding parts to the same standard demanded in aircraft engines. That precision and discipline carries through into every tank we build.

The Alloy Shed Standard

Every tank at The Alloy Shed is hand-built and TIG welded. We don’t cut corners, because in motorsport, the details matter. Whether it’s a Subaru WRX header tank or a universal power steering reservoir, our welds are built to perform and built to last.
