Ti Alloy TIG Welding: Problems and Solutions
Welding Ti with the GTAW process presents specific difficulties beyond those encountered with steel. The alloy's high reactivity, leading to film formation that can cause voids and brittle formability, is a principal concern. Furthermore, the alloy's low thermal conductivity makes controlling the heat-affected zone difficult. Solutions involve meticulous cleaning to remove contaminants before and during fabrication, employing protective atmospheres like argon or He to prevent reaction, and utilizing controlled conditions – including lower voltage and appropriate feed rates. Proper technique and experience are vital for reliable Ti alloy joining.
Austenitic Steel Tig Welding: Achieving Strength
To obtain optimal joint strength when performing Tig welding on austenitic steel , several critical practices must be adhered to .
