Precision TIG or GTAW (Gas Tungsten Arc Welding)?

Precision TIG welding, also known as GTAW (Gas Tungsten Arc Welding), is versatile and can be applied across various industries, including aerospace, medical, and automotive. This process is suitable for welding all materials because the tungsten alloy electrode does not melt during the operation, allowing it to withstand very high temperatures. This enables welding at low currents and with materials as thin as 0.005 inches.

During the GTAW process, filler material or welding wire/rod is used externally and consumed as the weld is formed. Precision GTAW can be performed using DCEP (Direct Current Electrode Positive), which heats the electrode, or DCEN (Direct Current Electrode Negative), which heats the base material more

When welding aluminum, AC (Alternating Current) is typically used as it aids in cleaning and helps prevent potential porosity and cracks. An inert gas, usually argon, is used to shield the weld from contamination, though helium can also be used.

The GTAW process is known for its cleanliness and requires highly skilled welders, making it ideal for critical applications such as those in the aerospace industry. It produces high-quality welds, ensuring strong joints and an excellent appearance.
