Titanium TIG Welding: Difficulties and Solutions
Welding Ti with the gas tungsten arc process presents unique problems beyond those encountered with steel. The material's elevated reactivity, leading to film formation that can cause inclusions and poor ductility, is a critical concern. Furthermore, the alloy's reduced thermal response makes controlling the weld pool problematic. Remedies involve meticulous preparation to remove scale before and during joining, employing protective atmospheres like Ar or He to minimize scale formation, and utilizing careful conditions – including lower amperage and suitable feed rates. Proper method and expertise are crucial for reliable titanium welding.
Austenitic Steel Tig Welding: Achieving Strength
To secure maximum joint strength when performing Tig welding on stainless steel , several critical practices must be followed .
