3. How is the are started and stopped in GIAW?
4. What is the proper torch angle for welding a butt joint?
F
Answer
1. GTAW stands for Gas Tungsten Arc Welding.
2. Some advantages of GTAW include precise control of heat input, high-quality welds with minimal distortion, and the ability to weld a variety of metals.
3. In GIAW (Gas Inert Arc Welding), the arc is started by touching the tungsten electrode to the workpiece and then quickly lifting it away to establish the arc. The arc is stopped by removing the electrode from the workpiece.
4. The proper torch angle for welding a butt joint is typically between 60-70 degrees from the workpiece.
