Ti Alloy GTAW Joining: Problems and Solutions
Welding titanium with the GTAW process presents specific difficulties beyond those encountered with carbon steel. The metal's significant reactivity, leading to oxide formation that can cause porosity and poor formability, is a major concern. Furthermore, the alloy's reduced thermal response makes controlling the HAZ challenging. Approaches require meticulous preparation to remove scale before and during CNC machining parts fabrication, employing inert gases like pure argon or helium to minimize oxidation, and utilizing careful conditions – including lower voltage and correct welding rates. Proper technique and experience are vital for successful Ti fabrication.
