Titanium Filler Rod

Titanium Filler Rods are high-performance welding consumables designed for joining titanium and titanium alloy components in demanding industrial applications. They offer excellent corrosion resistance, high strength-to-weight ratio, and reliable metallurgical performance when used with appropriate welding procedures and shielding conditions.

Changsheng Titanium supplies titanium filler rods in Grade 5 (Ti-6Al-4V) and Grade 9 (Ti-3Al-2.5V), suitable for precision welding processes including Gas Tungsten Arc Welding (GTAW/TIG) and Plasma Arc Welding (PAW).

Filler rods can be supplied in straight lengths or according to customer-specified dimensions, with material certification and inspection documentation available upon request.
