Ti GTAW Joining: Difficulties and Approaches

Welding Ti with the gas tungsten arc process presents specific problems beyond those encountered with steel. The alloy's elevated reactivity, leading to scale formation that can cause porosity and poor toughness, is a major concern. Furthermore, Ti's low thermal heat transfer makes managing the weld pool challenging. Approaches include meticulous degreasing to remove scale before and during joining, employing protective atmospheres like pure argon or helium to prevent reaction, and utilizing controlled welding parameters – including decreased amperage and appropriate welding rates. Correct procedure and experience are crucial for reliable Ti joining.
