Titanium TIG Fabrication: Problems and Solutions
Welding Ti alloys with the GTAW process presents distinct problems beyond those encountered with ferrous metals. The material's significant reactivity, resulting film formation that can cause voids and brittle formability, is a principal concern. Furthermore, Ti's reduced thermal heat transfer makes regulating the HAZ challenging. Solutions require meticulous cleaning to remove scale before and during aluminum weld joining, employing inert gases like Ar or helium to inhibit oxidation, and utilizing careful welding parameters – including decreased power and suitable travel speeds. Adequate method and experience are essential for successful Ti joining.
Austenitic Steel Tig Welding: Maximizing Strength
To guarantee superior joint strength when performing Tig welding on 304 stainless, several critical practices must be followed .
