Ti Alloy Gas Tungsten Arc Fabrication: Problems and Approaches
Welding titanium with the GTAW process presents unique challenges beyond those encountered with carbon steel. The material's elevated reactivity, resulting oxide formation that can cause inclusions and brittle ductility, is a principal concern. Furthermore, Ti's low thermal conductivity makes regulating the HAZ challenging. Solutions include meticulous degreasing to remove oxides before and during joining, employing inert gases like pure argon or a helium mix to prevent reaction, and utilizing controlled welding parameters – including decreased amperage and suitable travel speeds. Proper method and experience are vital for high-quality Ti welding.
