Ti GTAW Fabrication: Challenges and Remedies
Welding titanium with the GTAW process presents specific challenges beyond those encountered with carbon steel. The material's elevated reactivity, producing scale formation that can cause voids and poor formability, is a principal concern. Furthermore, the alloy's reduced thermal response makes regulating the heat-affected zone problematic. Remedies involve meticulous cleaning to remove oxides before and during joining, employing inert gases like argon or He to prevent scale formation, and utilizing precise welding parameters – including decreased voltage and suitable travel speeds. Correct method and expertise are vital for successful Ti alloy joining.
