Titanium GTAW Welding: Difficulties and Solutions
Welding Ti with the GTAW process presents specific challenges beyond those encountered with steel. The metal's elevated reactivity, leading to film formation that can cause voids and poor ductility, is a critical concern. Furthermore, the alloy's low thermal conductivity makes managing the weld pool problematic. Solutions require meticulous cleaning to remove contaminants before and during joining, employing shielding gases like pure argon or He to prevent reaction, and utilizing precise settings – including decreased voltage and correct travel speeds. Adequate technique and expertise are essential for high-quality Ti fabrication.
