Dialing In GTAW Torch Configuration

Gas tungsten arc welding (GTAW) is widely valued for its precision, arc stability, and clean bead appearance. However, those results only happen when the setup matches the material. No two alloys respond the same after the arc is struck. A configuration that works flawlessly on one metal might lead to erratic starts, poor fusion, or oxidation issues on another. Factors like thermal conductivity, oxide behavior, and alloy reactivity influence arc behavior and weld pool formation.
