Titanium Welding Wire for Heat Exchanger and Chemical Equipment Fabrication
Titanium welding wire must be selected with the base metal, joint design, welding procedure, service environment and governing fabrication code. Filler classification, diameter, cleanliness and traceability should be defined before production welding.
Base Metal and Filler Compatibility
ERTi-2 is commonly evaluated when welding Grade 2 commercially pure titanium, while ERTi-7 is evaluated for compatible palladium-alloyed applications. ERTi-5 is Ti-6Al-4V filler and serves a different material family. The approved welding procedure and engineering review control the final selection; matching a trade name alone is insufficient.
Ordering Data
| Item | Required information |
|---|---|
| Classification | ERTi designation and invoked filler-metal specification |
| Form | Straight cut length, spool or order-specific package |
| Diameter | Nominal size and tolerance |
| Surface | Clean, dry and protected from contamination |
| Documents | Certificate, heat or lot traceability and inspection records |
Cleanliness and Shielding
Titanium welding is sensitive to contamination at elevated temperature. Storage, handling, joint cleaning, shielding gas purity, torch and trailing coverage, interpass control and wire feeding should follow the qualified procedure. Discoloration criteria and repair rules must be defined by the fabricator.

FAQ
Can welding wire be selected only from the base-metal grade?
No. The joint, procedure, code, service and design requirements also control filler selection.
Why does wire packaging matter?
Packaging helps protect clean wire from dirt, moisture, handling damage and mixed-lot use before welding.
