Titanium Welding Wire and Filler Rods for Titanium Fabrication
Supply envelope: straight rod runs 0.8 to 6.0 mm diameter in lengths to 6000 mm, coil wire 0.8 to 12 mm diameter and spool wire 0.01 to 6.35 mm diameter. These are the titanium wire program limits, not validated welding diameters or a promise that every grade, form and diameter combination is available; the AWS A5.16 filler grade, welding process and equipment determine which row applies.
Beiyu supplies titanium welding wire and titanium filler rods for welding titanium sheet, plate, tube, pipe, fittings, equipment parts and fabricated titanium assemblies. Titanium welding wire is commonly used in chemical equipment, aerospace-related fabrication, medical-related manufacturing, marine systems and industrial repair or production work.
Wire grade should be selected according to base material grade, welding process, service environment and project specification. ERTi-2 is commonly used with Grade 2 titanium, while ERTi-5 is selected for Ti-6Al-4V materials. For corrosive media, ERTi-7 or other specified filler grades may be required by the welding procedure.
Grades and Standards
| Common filler grades | ERTi-1, ERTi-2, ERTi-5, ERTi-7 and project-specified titanium filler wire grades. |
|---|---|
| Common reference | AWS A5.16 for titanium and titanium alloy welding electrodes and rods. |
| Supply forms | Straight rods, coils, spools or cut lengths depending on welding process and packaging requirement. |
| Surface condition | Clean, bright, pickled or polished surface according to grade and welding requirement. |
Diameter, Supply Form and Cleanliness
RFQs should specify grade, diameter, straight length or coil size, spool requirement, surface condition, quantity and packaging method. Common welding wire requirements include clean surface, stable diameter tolerance and protection against contamination during packing and shipment.
For critical welding projects, buyers should confirm whether the wire must match a qualified welding procedure specification. Base material grade, shielding gas practice and cleanliness control should be reviewed by the welding engineer.
Welding Wire Form Envelope and Process Check
Beiyu's June 2026 product brochure lists ERTi filler grades in a three-form titanium wire program. These are form-level program limits; the AWS A5.16 filler grade, welding process and equipment determine which row applies to an order.
| Supply form | General program limit | Welding RFQ check |
|---|---|---|
| Straight rod | 0.8 to 6.0 mm diameter, length to 6000 mm | State cut length, straightness and bundling |
| Coil wire | 0.8 to 12 mm diameter | State process, coil weight and feed requirement |
| Spool wire | 0.01 to 6.35 mm diameter | State process, spool and core format, winding and feed diameter |
The limits are a general wire capability envelope, not validated welding diameters, stock or proof that every ERTi grade, form, diameter and surface combination is available. Beiyu confirms the filler grade and supply form against the welding process or WPS before quotation.

FAQ
Which titanium filler wire is used for Grade 2 titanium?
ERTi-2 is commonly used for welding Grade 2 titanium, but the final selection should follow the project welding procedure and service environment.
Can titanium welding wire be supplied as straight rods?
Yes. Titanium welding wire can be specified as straight rods, coils or spools depending on welding process and packaging requirement.
What information is needed for a titanium welding wire RFQ?
Send filler grade, diameter, supply form, length or spool requirement, quantity, surface condition, certificate requirement and base material grade if welding grade selection needs review.

Specification detail with sources
Welding filler and wire supplied as a mill product are two classifications sharing one word. A filler metal is classified under a welding consumable specification, and the ERTi designations come from that document rather than from a titanium product specification. Which one the order names decides what the certificate reports and which table a receiving laboratory checks it against, so the specification belongs on the order line next to the grade rather than being inferred from the word wire.
Composition figures are produced by named methods rather than by a general practice. In the bar and billet specification ASTM B348, which is the titanium product specification we work from directly, the methods are named in the document itself: ASTM E1409 for oxygen and nitrogen, ASTM E1447 for hydrogen and ASTM E1941 for carbon, with rounding to ASTM E29 before a value is compared to a limit (ASTM B348, referenced documents and test methods). Filler metal is certified under its own specification, and the method behind each figure is worth asking about there for the same reason. In ASTM B348 the composition limits are heat analysis limits taken at the melt, which is why a later product analysis is read with its own tolerance rather than treated as the same number. The order is also where the physical form is settled, since spool, coil and straight cut lengths are a separate question from diameter and grade. Beiyu Titanium supplies welding wire with an EN 10204 3.1 mill test certificate carrying heat number traceability, with the reporting scope set by the order.
