AERO TIG Test Fixture – Precision Aerospace Weld Certification Ensure your welds meet industry-standards with the AERO TIG Test Fixture, built for aerospace-grade accuracy and certification work. Designed for rigorous testing in positions 1G through 4G, this fixture supports steel welds under ISO 3690 diffusion hydrogen requirements and helps maintain weld integrity through distortion-free performance. Key Features: ISO 3690-compliant design for diffusible hydrogen tests in steel welds. Billet 6061 aluminum manifold block and carbon steel clamping plates with high-tension M12 cap screws give durable, stable construction. Clamping system allows coupon gauge up to 3/8" (≈ 10 mm) or greater, with sample length of 230 mm (9″). Manifold with single port for argon gas or water-cooled option (AERO H₂O) for prolonged or heavy certification usage. Gas port: 1/4″ BSPT, back purging supported with 100% effectiveness. Work-side fixture plate has extended skirt for ergonomic welding; massive heat sink effect in block and clamping plates ensures minimal distortion. Why Choose This Fixture:Perfect for aerospace companies, training institutions, certification labs, or any welding operation that must meet AWS D17.1 or similar aerospace welding standards. Reduces errors, ensures consistency, supports welding in multiple positions, helps maintain certification quality. NOTE: AERO Water Cooled ( H2O) are made to order.
