Tungsten Inert Gas (TIG) and Gas Tungsten Arc Welding (GTAW) capabilities.
Specializing in GTAW & Tungsten inert gas (TIG) welding services for aerospace and defense applications.
Precision TIG welding can be used and applied to different industries such as aerospace, medical and automotive. GTAW process is suitable for welding all material due to electrode is not melting during the welding operation. The electrode is made of tungsten alloy which can tolerate a very high temperature and would allow to weld at low current and weld as thin as 0.005-inch-thick material.
Filler material or welding wire/rod is used externally and will be consumed during the welding process. Precision GTAW can be performed using DCEP (Direct Current Electro Positive) which focuses on heating the electrode and DCEN (Direct Current Electro Negative) which focuses on heating more the base material. AC is typically used when welding aluminum because it helps with the cleaning as well and to prevent potential porosities and cracks. Inert gas is used during the precision welding process and it works as a shield to protect the weld from contamination. Usually Argon is the most common gas for the GTAW process and sometimes helium is used as well.
The GTAW process is very clean process and requires high skilled welders to perform the welding. That is the reason that GTAW is used for very critical application such as the aerospace industry. GTWA produces a high-quality weld to assure successful joint and great appearance.
One of the potential issues to watch for while using the precision GTAW process is contamination. The base material and the filler material have to be extremely clean to produce a high-quality weld. If the base material, filler material is not clean and there was some moisture surrounding the weld area, that would affect the quality of the weld and perhaps will lead to potential defects. Our team is trained and experienced to produce a high-quality weld and successful results. We often consider GTAW as the more glamourous welding process.
Lynn Welding is qualified to weld per AWS D17.1, PWA 16, MIL-STD-2219, HS 191 and many other aerospace welding certifications.
