ERTi-2 TIG Rods
COREWELD Ti2 ERTi-2 TIG Rod is a commercially pure titanium filler metal for welding compatible titanium grades. Its unalloyed chemistry gives the weld deposit corrosion resistance equivalent to the base metal. Chemical processing, marine, and power generation fabricators specify ERTi-2 TIG rod for joints exposed to seawater, chlorides, and oxidising media.
ERTi-2 is the AWS A5.16 classification for a commercially pure titanium filler metal. It joins compatible titanium grades in TIG (GTAW) welding and suits applications that depend on corrosion resistance. Buyers also search for ERTi-2 filler wire, which names the same alloy in a different form.
Titanium absorbs oxygen, nitrogen, and hydrogen at welding temperatures, so inert gas must protect the weld pool, the hot rod tip, and the cooling weld. Base grade, service environment, and the approved welding procedure decide the final filler selection.

Compatibility with commercially pure titanium grades defines the main benefit of ERTi-2. The weld deposit retains the corrosion resistance required in oxidising service environments.
Weld quality still depends on process control. Argon shielding must cover the weld pool, the rod tip, and the trailing weld until it cools. Clean surfaces matter too, because oil, moisture and fingerprints cause porosity and embrittlement. An approved welding procedure ties these controls together.

Applications of ERTi-2 TIG Rod
- Chemical processing vessels and piping
- Heat exchangers and condensers
- Desalination and seawater systems
- Power generation condenser assemblies
- Marine and offshore components
- Pulp and paper bleaching equipment
- Pharmaceutical and food processing equipment
Manufacturing Process of ERTi-2 Filler Wire
- Material selection: commercially pure titanium with controlled oxygen, nitrogen, hydrogen, carbon, and iron.
- Alloying and melting: vacuum melting holds interstitial elements within ERTi-2 limits.
- Forming process: hot working and drawing reduce the ingot to wire, then straightening and cutting produce rod lengths.
- Composite filler metal selection: final chemistry gets matched against ERTi-2 limits before packing.
How to Select the Right ERTi-2 TIG Rod
Five checks narrow the choice:
- Confirm the base titanium grade.
- Select the required rod diameter and length.
- Check the classification against project specifications.
- Confirm corrosion and service requirements.
- Follow the approved welding procedure and titanium shielding requirements.

FAQ's
What is ERTi-2 TIG rod used for?
It is used to join commercially pure titanium in TIG welding of corrosion-resistant equipment, such as heat exchangers and chemical process piping.
What is the difference between ERTi-2 TIG rod and ERTi-2 filler wire?
Form only. Both carry the ERTi-2 composition, but the rod is supplied in straight cut lengths for manual TIG, while the filler wire comes on spools.
Which titanium grades can be welded using ERTi-2 filler metal?
Manufacturers list commercially pure Grades 1 to 4. Confirm the exact pairing against the COREWELD Ti2 datasheet and the approved welding procedure.
What sizes are available for COREWELD Ti2 TIG rods?
The official datasheet lists diameters and lengths. Send the required size with the base grade in an enquiry to confirm availability.
Which standard applies to ERTi-2 TIG rod?
AWS A5.16 and ASME SFA-5.16 cover the ERTi-2 classification, subject to certification.
Why is shielding important when welding titanium?
Hot titanium absorbs oxygen, nitrogen and hydrogen, which embrittle the weld. Argon shielding blocks that contamination until the metal cools.
