Titanium Welding Filler Wire

Titanium Welding Filler Wire is a premium-grade welding material specifically designed for joining titanium and titanium alloys, offering exceptional strength, corrosion resistance, and biocompatibility. Ideal for critical applications in aerospace, medical, marine, and industrial sectors, this filler wire ensures high-quality, durable welds that maintain the integrity of the base material. Its excellent resistance to harsh environments, including seawater and high temperatures, makes it a reliable choice for demanding conditions. Compatible with various welding processes such as TIG (GTAW), MIG (GMAW), and plasma arc welding, Titanium Welding Filler Wire produces clean, spatter-free welds with minimal porosity. Whether used for aircraft components, medical implants, or chemical processing equipment, this filler wire delivers unmatched performance, precision, and reliability, making it an essential solution for advanced welding needs.

 

 

 

Filler wire is classified by its chemical composition, usually matching ASTM/ASME or AWS specifications (e.g., AWS A5.16/ASME SFA-5.16).

 

Grade (Typical)	Common Name / Match For	Key Characteristics & Primary Uses
ERTi-1 / Grade 1	Commercially Pure Titanium	Excellent ductility, formability, and corrosion resistance. For welding CP Titanium Grade 1 & 2 under low stress.
ERTi-2 / Grade 2	The most widely used general-purpose grade.	Matches CP Titanium Grade 2 & 3. Balanced strength and ductility. Used for a vast majority of non-critical corrosion-resistant applications (e.g., chemical piping, heat exchangers).
ERTi-5 / Grade 5	Ti-6Al-4V (The "workhorse" alloy)	Matches Ti-6Al-4V (Grade 5). For high-strength structural applications in aerospace, medical implants, and high-performance automotive.
ERTi-23 / Grade 23	Ti-6Al-4V ELI (Extra Low Interstitial)	Higher purity, lower oxygen/iron content than Grade 5. Medical industry standard for fracture-critical and low-temperature implants due to superior fracture toughness and ductility.
ERTi-9 / Grade 9	Ti-3Al-2.5V	For welding Grade 9 tubing (hydraulic systems, aerospace). Good strength and creep resistance at moderate temperatures.
ERTi-7 / Grade 7	Pd-alloyed (0.12-0.25% Pd)	Enhanced crevice corrosion resistance in reducing acids. Used for welding Grade 7 & 16 in aggressive chemical environments.
