ANS:B - TIG

Titanium can be easily welded using TIG (Tungsten Inert Gas) welding. TIG welding, also known as gas tungsten arc welding (GTAW), is commonly used for welding titanium and other reactive metals due to its ability to produce high-quality welds with precise control over the welding parameters. In TIG welding, a non-consumable tungsten electrode is used to create the arc, and a shielding gas, typically argon or helium, is used to protect the weld area from atmospheric contamination. This process allows for clean, precise, and high-quality welds, making it well-suited for welding titanium, which is known for its high strength, low weight, and reactivity.
