Ti Gas Tungsten Arc Joining: Challenges and Solutions
Welding titanium with the gas tungsten arc process presents specific challenges beyond those encountered with ferrous metals. The alloy's elevated reactivity, producing oxide formation that can cause porosity and brittle ductility, is a principal concern. Furthermore, Ti's low thermal response makes regulating the heat-affected zone challenging. Remedies require meticulous degreasing to remove scale before and during fabrication, employing inert CNC machining parts gases like Ar or helium to minimize scale formation, and utilizing controlled settings – including lower voltage and suitable feed rates. Adequate method and experience are crucial for high-quality Ti welding.
