Titanium Gas Tungsten Arc Joining: Challenges and Approaches
Welding Ti alloys with the GTAW process presents distinct challenges beyond those encountered with ferrous metals. The welding titanium metal's high reactivity, leading to oxide formation that can cause voids and reduced ductility, is a principal concern. Furthermore, the alloy's low thermal conductivity makes controlling the weld pool difficult. Remedies require meticulous degreasing to remove oxides before and during fabrication, employing protective atmospheres like argon or a helium mix to minimize oxidation, and utilizing careful conditions – including reduced amperage and correct welding rates. Adequate technique and experience are essential for successful Ti welding.
