What is the best practice for the torch angle in GTAW?

Holding the torch at a 15 to 25-degree angle in the direction of travel is considered the best practice in Gas Tungsten Arc Welding (GTAW) because this angle facilitates optimal control of the arc and the heat input to the workpiece. When the torch is angled slightly forward, it helps in directing the heat into the weld pool effectively, allowing for better penetration and fusion of the base metals. This position also helps in avoiding excessive spatter and ensures a more stable arc, which is crucial for producing high-quality welds.

Additionally, this angle aids in maintaining visibility of the weld pool, allowing the welder to better monitor the molten metal and adjust their technique as necessary, enhancing overall accuracy and consistency during the welding process.
