Ti GTAW Joining: Problems and Solutions
Welding titanium with the gas tungsten arc process presents precision metal products distinct challenges beyond those encountered with ferrous metals. The material's elevated reactivity, producing film formation that can cause voids and brittle formability, is a principal concern. Furthermore, Ti's minimal thermal heat transfer makes managing the HAZ challenging. Solutions involve meticulous preparation to remove scale before and during welding, employing protective atmospheres like pure argon or a helium mix to inhibit scale formation, and utilizing careful settings – including reduced power and suitable travel speeds. Adequate technique and skill are essential for high-quality Ti fabrication.
