Ti Alloy GTAW Welding: Difficulties and Remedies
Welding titanium with the gas tungsten arc process presents distinct problems beyond those encountered with carbon steel. The alloy's high reactivity, resulting film formation that can cause inclusions and poor formability, is a critical concern. Furthermore, titanium's low thermal response makes regulating the HAZ problematic. Remedies involve meticulous preparation to remove contaminants before and during joining, employing inert gases like pure argon or a helium mix to inhibit reaction, and utilizing careful welding parameters – including decreased amperage and appropriate welding rates. Adequate technique and skill are vital for reliable Ti joining.
Stainless Steel Tig Welding: Maximizing Strength
To secure optimal joint strength when conducting Tig welding on 304 stainless, several critical practices must be followed .
