Ti Alloy GTAW Fabrication: Problems and Remedies
Welding Ti with the GTAW process presents specific challenges beyond those encountered with ferrous metals. The alloy's high reactivity, producing oxide formation that can cause inclusions and poor ductility, is a critical concern. Furthermore, Ti's low thermal response makes managing the weld pool difficult. Remedies include meticulous preparation to remove oxides before and during fabrication, employing inert gases like pure argon or a helium mix to inhibit oxidation, and utilizing careful conditions – including lower amperage and correct travel speeds. Adequate method and expertise are vital for reliable Ti alloy fabrication.
