Ti Gas Tungsten Arc Fabrication: Difficulties and Approaches
Welding Ti alloys with the TIG process presents unique challenges beyond those encountered with steel. The alloy's significant reactivity, resulting oxide formation that can cause porosity and brittle formability, is a principal concern. Furthermore, titanium's minimal thermal heat transfer makes controlling the heat-affected zone challenging. Solutions require meticulous preparation to remove oxides before and during fabrication, employing protective atmospheres like Ar or helium to prevent scale formation, and utilizing careful conditions – including reduced power and correct feed rates. Correct technique and experience are vital for successful titanium fabrication.
Austenitic Steel Tig Welding: Achieving Strength
To obtain superior joint strength when conducting Tig welding on 304 stainless, several important practices must be observed.
