Description
AWS A5.16 Titanium Welding Wire is specifically designed for the welding of titanium and titanium
alloys. It offers excellent weldability, corrosion resistance, and mechanical
properties, making it suitable for demanding applications in aerospace,
chemical processing, marine, and medical industries.
This wire is available in multiple grades, diameters, and finishes
to meet various welding requirements. The most commonly used grades
include ErTi-1, ErTi-2, ErTi-5, and ErTi-7.
Titanium welding wires under AWS A5.16 / ASTM B863 / ASTM F67 / ASTM F136 standards are used in GTAW (TIG), GMAW (MIG), and SMAW processes. Among them, ErTi-2 is widely preferred for both root and fill passes due to its balanced strength, ductility, and corrosion resistance.
