True The use of filler material is optional in TIG welding. True TIG welding is suitable for welding thin materials. True The torch angle during TIG welding should be 90 degrees to the workpiece. False Argon is the most commonly used shielding gas in TIG welding. True TIG welding can be performed in all positions, including overhead. True The tungsten electrode must not touch the workpiece during welding. 2 True TIG welding can be used on both ferrous and non-ferrous metals. True The heat input in TIG welding can be controlled by adjusting the amperage. True A clean and well-prepared surface is crucial for quality TIG welds. True The size of the tungsten electrode affects the weld quality. True TIG welding requires a constant current power source. True The arc length should be kept as short as possible during TIG welding. False It is safe to wear synthetic clothing while TIG welding. Post-weld cleaning is unnecessary if the weld is visually acceptable. TIG welding produces less spatter compared to other welding processes. Using the correct filler rod is important for the integrity of the weld. The travel speed of the torch does not affect the heat input. Preheating the workpiece can improve the quality of TIG welds. TIG welding is often used for applications requiring high precision. The electrode should be ground to a point for optimal performance. Backhand welding technique is commonly used in TIG welding. 3 It is acceptable to use a contaminated tungsten electrode for welding. TIG welding can be automated for consistent results. The shielding gas flow rate has no
