Ti Alloy GTAW Fabrication: Difficulties and Approaches
Welding Ti with the GTAW process presents distinct challenges beyond those encountered with carbon steel. The alloy's significant reactivity, producing film formation that can cause voids and poor ductility, is a critical concern. Furthermore, Ti's reduced thermal conductivity makes managing the heat-affected zone difficult. Remedies require meticulous cleaning to remove scale before and during joining, employing protective atmospheres like Ar or He to prevent reaction, and utilizing precise conditions – including decreased power and correct welding rates. Adequate technique and skill are crucial for high-quality titanium fabrication.
Stainless Steel Tig Welding: Ensuring Strength
To secure optimal joint strength when conducting Tig welding on austenitic steel , several essential practices must be followed .
