ERTi-7 Titanium Welding Wire for Grade 7 Titanium Welding
Beiyu supplies ERTi-7 titanium welding wire for welding Grade 7 titanium and titanium equipment used in corrosion-resistant service. ERTi-7 contains palladium and is selected when the base metal or project specification requires Grade 7-compatible filler metal for chemical, seawater, brine or chloride-containing environments.
Welding filler metal should be specified by grade, standard, diameter, form and certificate requirement. Buyers should also confirm the base metal grade, welding process, shielding plan and whether the wire will be supplied as straight TIG rods, coils or spools.
Grade and Standard
| Filler metal | ERTi-7 titanium welding wire, UNS R52401. |
|---|---|
| Common standard | AWS A5.16 / ASME SFA-5.16 for titanium and titanium alloy welding electrodes and rods. |
| Related base metal | Grade 7 titanium or project-specified corrosion-resistant titanium assemblies. |
| Supply form | Straight TIG rods, coils or spools according to welding process and order requirement. |
Diameter, Form and Surface Condition
RFQs should specify wire diameter, straight rod length, spool size or coil requirement, surface condition, quantity and packaging. For TIG welding rods, buyers should confirm cut length and bundling requirement. For MIG or automated welding, spool type and winding requirement should be included.
Titanium welding wire must be kept clean and protected from surface contamination. If the wire will be used for critical corrosion-resistant equipment, the buyer should define certificate, traceability and inspection requirements before order confirmation.
Common Applications
- Welding Grade 7 titanium plate, sheet, tube and fabricated equipment
- Chemical processing equipment exposed to corrosive media
- Seawater, brine and desalination-related titanium assemblies
- Heat exchanger, vessel and piping repair or fabrication
- Drawing-based projects requiring ERTi-7 filler metal
Inspection and Documentation
Buyers can request mill test certificate, EN10204 3.1 documentation, heat number traceability, chemical composition and dimensional inspection. PMI testing, surface inspection or third-party inspection can be specified when required by the purchase order.
Packaging and Export Information
ERTi-7 wire should be packed to protect the surface from dust, oil, moisture and mechanical damage. Straight rods may be packed in tubes or boxes, while spools should be wrapped and labeled by grade, diameter, heat number and quantity. Export packing should match the wire form and shipment method.
ERTi-7 Welding Wire Specification Snapshot
| Classification | AWS A5.16 ERTi-7 titanium filler wire. |
|---|---|
| Grade match | Ti-Pd filler for Grade 7 parent metal and related reducing-acid service. |
| Forms | Straight TIG lengths and spooled MIG wire by order. |
| Diameter | Common RFQ range around 0.8-4.0 mm, confirmed by form and welding process. |
| Certificate | EN 10204 3.1 MTC with chemistry including Pd. |
State diameter, form, quantity and the parent grade being welded. For Ti-Pd equipment, matching the filler to the Grade 7 parent helps keep the weld-metal corrosion route aligned with the base material.

FAQ
What is ERTi-7 titanium welding wire used for?
ERTi-7 is used as titanium filler metal for Grade 7 titanium and corrosion-resistant titanium assemblies where the welding specification requires this grade.
Which standard applies to ERTi-7 wire?
AWS A5.16 / ASME SFA-5.16 is commonly used for titanium and titanium alloy welding electrodes and rods, including ERTi-7.
What should be included in an ERTi-7 RFQ?
Send standard, grade, diameter, form, rod length or spool size, quantity, packaging, certificate requirements and the base metal grade if known.
Procurement Notes for ERTi-7 Welding Wire
ERTi-7 welding wire RFQs should specify AWS A5.16 grade, diameter, straight rod or spool form, length, packing quantity and the base material to be welded. Grade 7 filler wire is commonly selected for titanium fabrication where palladium-bearing corrosion resistance is required, so buyers should confirm whether the welded part uses Grade 7 sheet, pipe, tube, flange or equipment components.
Useful purchasing details include heat traceability, chemical composition, certificate format, surface cleanliness, diameter tolerance and sealed packing requirement. For chemical equipment or pressure-related fabrication, include WPS reference, inspection requirement and whether EN10204 3.1 documentation is needed.

What an ERTi-7 order fixes beyond the classification
The filler classification settles which composition band applies. What decides whether the wire runs and whether the weld is accepted are order fields that sit outside the classification.
| Field | What it controls | Where it belongs |
|---|---|---|
| Diameter with tolerance | Feed behaviour and arc stability | Stated together |
| Supply form | Straight cut lengths, coil or spool | Its own line |
| Surface condition | Cleanliness at the arc | Stated apart from the delivery condition |
| Packing | Protection against contamination in transit | Named on the order, since defaults exist |
What the certificate carries
| Field | Beiyu position |
|---|---|
| Certificate type | EN 10204 3.1 mill test certificate |
| Traceability | Heat number, carried through to the delivered pieces |
| Composition basis | Reported against the specification the order names, by the methods it references |
| Reporting scope | Set by the order, which is why the order should state it |
A filler enquiry that carries the diameter tolerance, the supply form and the reporting scope can be quoted on the first pass.

Specification detail with sources
The Beiyu Titanium supply ranges publish titanium welding wire in three forms: straight wire at Ø0.8 mm to 6.0 mm in lengths to 6000 mm, coil wire at Ø0.8 mm to 12 mm, and spool wire at Ø0.01 mm to 6.35 mm. The grade column pairs Grade 7 with the filler designation ERTi-7, in the same way it pairs Grade 2 with ERTi-2 and Grade 12 with ERTi-12.
That pairing is why a welding wire enquiry should carry both names. The Grade number identifies the alloy and the ERTi number identifies it as filler metal, and a certificate that reports one without the other leaves the welding engineer to infer the rest. The documents listed against titanium wire are ASTM B863 with its ASME adoption SB863, AWS A5.16, ASTM F67, ASTM F136 and ISO 5832-2 and 5832-3, listed for the wire range as a whole rather than against individual forms, so the order names which one the certificate reports against.
