Ti Alloy TIG Welding: Problems and Solutions
Welding Ti with the TIG process presents unique challenges beyond those encountered with steel. The alloy's elevated reactivity, resulting film formation that can cause porosity and poor formability, is a critical concern. Furthermore, titanium's reduced thermal response makes regulating the weld pool difficult. Approaches require meticulous degreasing to remove contaminants before and during fabrication, employing protective atmospheres like Ar or a helium mix to prevent reaction, and utilizing controlled welding parameters – including lower amperage and appropriate travel speeds. Proper method and skill are essential for reliable titanium joining.
304 Stainless Tig Welding: Achieving Strength
To obtain optimal joint strength when conducting Tig welding on stainless steel , several essential practices must be observed.
