Combining advanced technology with a team of skilled welding specialists, we provide durable, high-precision solutions for some of the most demanding applications in Healthcare, Fusion & Nuclear, and Renewable Energy sectors.
Our Oxfordshire-based team of coded welders brings extensive experience in all aspects of fabrication and welding for highly regulated industries. We specialise in semi-automated autogenous seam welding (ASW) for aluminium sheet fabrications - using DC current to achieve full penetration up to 6.5mm in a single pass, eliminating the need for filler wire. The result: exceptional weld integrity, consistency, and efficiency.
What is Aluminium Seam Welding?
Autogenous Seam Welding (ASW) is a resistance welding technique that joins aluminium sheets with exceptional precision and strength. Continuous longitudinal seam welding offers efficient, repeatable performance for high-volume production across various thicknesses and widths.
Applications
- Healthcare – lightweight aluminium housings and medical equipment.
- Energy – corrosion-resistant aluminium assemblies for renewables.
- Transport – lightweight structural welds for rail and automotive.
Compliance & Standards
- Performed under ISO 9001, 14001, and 45001 certifications.
- Welds validated to EN 13445 and sector-specific standards.
- Full QA traceability for safety-critical projects.
