Ti Alloy Gas Tungsten Arc Welding: Problems and Approaches
Welding Ti alloys with the gas tungsten arc process presents specific problems beyond those encountered with carbon steel. The material's elevated reactivity, leading to oxide formation that can cause porosity and poor toughness, is a major concern. Furthermore, titanium's low thermal heat transfer makes regulating the heat-affected zone pipe bending difficult. Solutions require meticulous preparation to remove oxides before and during joining, employing protective atmospheres like argon or helium to prevent reaction, and utilizing controlled settings – including decreased power and appropriate welding rates. Correct technique and expertise are vital for successful Ti welding.
