Aircraft exhaust components take a beating – from high temperatures to constant vibration and corrosive gases. AtHartzell Aviation, we know that durability isn’t optional—it’s essential.

That’s why in-house TIG welding plays a critical role in the performance and longevity of the exhaust systems we support and service. Whether through our own FAA-certified welding operations at our Fort Lauderdale (FXE) facility, or in collaboration with Acorn Welding – a division of Hartzell Aerospace Welding (HAW) we deliver precision, strength, and full regulatory compliance with every weld.

As the designated MRO arm of Hartzell Engine Tech,Hartzell Aviationworks in lockstep with HAW to provide aircraft owners with a seamless experience—combining trusted repair capabilities with world-class manufacturing and welding expertise.

Why TIG Welding Matters in Aviation

TIG (Tungsten Inert Gas) welding, also known as GTAW, uses a non-consumable tungsten electrode and inert gas shielding to create clean, precise welds. This level of control is vital for thin-wall tubing, complex assemblies, and the high-performance metals used in aircraft exhaust systems.

FAQs: TIG Welding & Aircraft Exhaust

What is TIG welding and why is it important?
TIG welding creates clean, high-strength welds using a tungsten electrode and shielding gas. It’s essential for aviation applications where heat, vibration, and joint integrity are critical.

DoesHartzell Aviationperform TIG welding in-house?
Yes. Our Fort Lauderdale (FXE) location offers FAA-certified TIG welding for exhaust components, delivering fast turnaround and tight quality control.

What materials benefit most from TIG welding?
Stainless steel, Inconel, and titanium—all commonly used in aircraft exhaust systems—are ideal candidates for TIG welding due to their strength and heat resistance.

How does in-house welding improve reliability?
It allows for real-time quality oversight, consistent processes, and a faster response when repairs or customizations are needed—leading to longer-lasting components.

AreHartzell Aviationand Acorn Welding part of the same organization?
Yes. BothHartzell Aviationand Acorn Welding operate under Hartzell Engine Tech and its welding division, Hartzell Aerospace Welding.Hartzell Aviationhandles MRO and distribution, while Acorn Welding provides manufacturing and fabrication. Together, we cover the full spectrum of exhaust system needs.
