TIG Welding in Aerospace: Why AWS D17.1 Class A Certification Matters
What TIG welding is, what AWS D17.1 Class A certification requires, and the alloys and APU parts Jets MRO Miami welds.
In aerospace, there’s no room for error—especially when it comes to welding. Every joint, seam, and weld must meet the highest structural and safety standards. That’s why TIG welding, when done by certified experts, is fundamental to reliable aircraft component repair.
At Jets MRO Miami, our technicians hold AWS D17.1, Class A certification—the industry’s most rigorous standard for aerospace fusion welding. Here’s why that matters to your fleet’s airworthiness, regulatory compliance, and cost efficiency.
What Is TIG Welding?
TIG (Tungsten Inert Gas) welding is a precise and high-integrity method used to join metals using a non-consumable tungsten electrode and inert shielding gas. It’s ideal for intricate, high-value components—exactly the kind found in modern aircraft.
At Jets MRO Miami, we use TIG welding to repair and restore critical parts such as:
- APU housings
- Diffusers and shrouds
- Compressor assemblies
- Bearing carriers and support rings
- High-temp engine components
AWS D17.1 Class A – What It Means for You
AWS D17.1 is the gold standard for aerospace welding, detailing qualification procedures, inspection criteria, and documentation requirements.
Class A is the most stringent level within the standard, reserved for components where weld failure is not an option—pressurized systems, rotating parts, and flight-critical structures.
At Jets MRO Miami, this means:
- Welders pass rigorous testing and recertification
- Welding processes meet FAA/EASA and OEM expectations
- Full traceability and material control on every repair
- Inspections follow strict NDT protocols to verify structural soundness
