AWS A5.16 ERTi-2 Titanium TIG Welding Rods
Baoji Yibaite New Materials Technology Co., Ltd. specializes in supplying AWS A5.16 ERTi-2 titanium TIG welding rods and wires. The company is located in "China Titanium Valley" - Baoji, and is a high-tech enterprise dedicated to the processing and sales of titanium and its alloys.
AWS A5.16 ERTi-2 is widely recognized as the "backbone" of the titanium welding consumables family, delivering an exceptionally pure chemical composition and precise wire diameter control. This commercially pure titanium filler metal offers an optimal balance of superior weld puddle fluidity, stable arc characteristics, and outstanding crack resistance during the thermal cycle. Designed for gas tungsten arc welding (GTAW/TIG), it ensures high-purity, leak-free, and ductile joints that match or exceed the corrosion resistance of Grade 2 base metals. Our ERTi-2 titanium welding rods are the premier choice for fabricating chemical processing vessels, power plant heat exchangers, marine piping systems, and high-performance automotive exhaust welds.
Products Description
High Chemical Purity and Filler Performance
- Interstitial elements (Oxygen, Nitrogen, Carbon, Hydrogen) are strictly controlled. Purity is at least 99.2%
- Iron and oxygen contents are balanced. The weld metal keeps high ductility and impact toughness. This prevents post-weld embrittlement.
Crack and Corrosion Resistance
- A dense oxide film forms on the weld joint. Its corrosion resistance matches Grade 2 titanium base metals.
- The weld resists hot wet chlorides, sea water, and nitric acid. Welded seams stay intact in harsh chemical environments.
Arc Stability and Puddle Fluidity
- Features ultra-clean surface technology to ensure stable arc ignition, minimal spatter, and smooth metal transfer.
- Delivers excellent weld puddle fluidity, allowing weld operators to easily achieve uniform, neat, and beautifully formed fish-scale weld beads (GTAW/TIG).
Diameter Control and Feeding
- Manufactured with strict dimensional tolerances to ensure absolute roundness and uniform diameter along the entire rod length.
- Free of scratches, kinks, or drawing lubricants, preventing wire-feeding jams and eliminating the risk of introducing hydrocarbons into the weld pool.
High-Pressure Piping Welds
- Engineered specifically for gas tungsten arc welding (TIG) to seal critical joints in titanium heat exchangers, pressure vessels, and automotive exhaust systems.
- Guarantees high-ductility joints capable of handling cyclical thermal expansion, constant vibration, and internal pressure pulses.
.
AWS Certification and X-Ray Quality
- Fully compliant with AWS A5.16 / ASME SFA-5.16 ERTi-2 standards, enabling seamless global project acceptance.
- Every batch undergoes rigorous inspection, ensuring the filler metal meets Grade 1 X-ray radiographic quality with zero porosity, inclusions, or undercut defects.

Application Fields
AWS A5.16 ERTi-2 titanium TIG welding rods are widely applied in:
-
Chemical and Petrochemical Equipment:Titanium pressure vessels are welded using this process. It is also used for chemical reactors and distillation columns. Storage tanks and aggressive fluid piping networks require these welds.
-
Power Generation & Heat Exchangers: Shell-and-tube heat exchangers are fabricated this way. The process includes tube-to-tubesheet welding. Power plant surface condensers and industrial evaporators also use this method.
-
Marine Engineering and Desalination: Seawater desalination piping systems need sealed joints. Offshore platform splash zone equipment is welded. Shipboard cooling systems and ballast water piping also rely on this technology.
-
High-Performance Automotive Exhaust Welding: Custom titanium motorcycle exhausts are TIG welded. Racing car downpipes and mufflers use this process. Pie-cuts and thin-walled tubing connections are also welded.
-
Environmental Protection & Water Treatment: Industrial wastewater treatment equipment is welded. Sewage purification systems use this method. Flue gas desulfurization (FGD) scrubbers also require these welds.
