Barren Precision Welding

Stainless Steel Pipe Welding - Case Study

Case Study Overview

Leanfabs partnered with SPA Design UK, a leading manufacturer of motorsport instrumentation and components, to produce a batch of precision aluminium cylinders for a critical product line. The project required TIG welding specialists capable of delivering airtight, full-penetration welds on thin-wall Aluminium 6082 with exceptional cosmetic quality. Using custom purging rigs, controlled heat inputs, and meticulous surface handling, Leanfabs achieved flawless results across all units. Each weld met SPA Design’s rigorous standards for strength, consistency, and visual finish—earning praise for the “clean weld finish” and “perfect repeatability” essential in high-performance automotive applications.
