Ti Alloy Gas Tungsten Arc Fabrication: Difficulties and Approaches
Welding Ti with the TIG process presents specific problems beyond those encountered with ferrous metals. The alloy's high reactivity, resulting oxide formation that can cause inclusions and brittle formability, is a major concern. Furthermore, the alloy's reduced thermal heat transfer makes controlling the heat-affected zone difficult. Solutions involve meticulous preparation to remove oxides before and during joining, employing protective atmospheres like pure argon or helium to prevent reaction, and utilizing controlled welding parameters – including lower power and suitable welding rates. Adequate technique and experience are essential for reliable titanium joining.
304 Stainless Tig Welding: Maximizing Strength
To guarantee maximum joint strength when performing Tig welding on stainless steel , several important practices must be observed.
