Ti TIG Fabrication: Difficulties and Remedies
Welding Ti with the TIG process presents unique challenges beyond those encountered with steel. The mig welding alloy's significant reactivity, leading to scale formation that can cause porosity and brittle ductility, is a major concern. Furthermore, Ti's minimal thermal conductivity makes managing the HAZ problematic. Approaches include meticulous preparation to remove oxides before and during joining, employing inert gases like pure argon or helium to minimize reaction, and utilizing careful welding parameters – including decreased power and appropriate feed rates. Correct technique and expertise are vital for successful titanium joining.
Austenitic Steel Tig Welding: Ensuring Strength
