Ti Gas Tungsten Arc Joining: Challenges and Solutions
Welding titanium with the GTAW process presents distinct challenges beyond those encountered with ferrous metals. The material's elevated reactivity, leading to film formation that can cause voids and reduced toughness, is a critical concern. Furthermore, the alloy's low thermal response stainless steel welding makes managing the heat-affected zone difficult. Solutions require meticulous preparation to remove oxides before and during fabrication, employing inert gases like argon or helium to inhibit reaction, and utilizing controlled settings – including reduced amperage and suitable travel speeds. Correct method and skill are vital for reliable Ti fabrication.
Stainless Steel Tig Welding: Achieving Strength
To obtain optimal joint strength when conducting Tig welding on 304 stainless, several essential practices must be observed.
