GTAW (TIG) Questions and Answers 100% Pass What is the ideal angle for the TIG torch when welding thin materials? The ideal angle for the TIG torch on thin materials is typically around 15 to 20 degrees to ensure even heat distribution. How does using a larger tungsten electrode affect the welding process? Using a larger tungsten electrode can increase heat input and stability but may require adjustments to arc length and travel speed. Why is it crucial to select the right gas fo...
