Quick answer. A titanium welding wire order needs a confirmed spool interface as well as the correct filler classification and wire diameter. Ask for a dimensioned spool drawing, package mass and identification, then compare them with the exact feeder and holder. A familiar spool name or package weight leaves important fitting details unresolved.
Separate filler selection from package compatibility
Confirm the filler classification and specification edition required by the approved welding procedure. AWS A5.16/A5.16M covers titanium and titanium-alloy welding electrodes, wire and rods; its classification is based on chemical composition. Spool fit is a separate equipment check. A matching package cannot make a different filler acceptable for the joint.
For the material selection step, use the ERTi-2, ERTi-5 and ERTi-7 comparison. Once the required classification is established, document how the proposed package will be mounted and paid off.
Request the dimensions behind the spool name
Use the supplier’s drawing to distinguish the flange outside diameter, overall width and central mounting bore. Include the hub or barrel geometry and any locating hole or adapter interface needed by the holder. Identify each dimension and its tolerance using the drawing’s own symbols. A nominal size designation alone does not describe all these features.
| RFQ detail | Confirm with the supplier | Compare at the feeder |
|---|---|---|
| Package geometry | Outside diameter, overall width, bore and relevant hub or locating features. | Holder drawing, enclosure clearance and retention arrangement. |
| Mass | Net wire mass, empty spool mass and total loaded mass. | The equipment’s stated package or load limit and its definition. |
| Spool construction | Flanged spool, basket or other agreed package; drawing and adapter needs. | Approved holder and adapter combination for the exact machine. |
| Pay-off arrangement | Expected mounting orientation, wire exit and secured free end. | Inlet position and the installation route in the equipment manual. |
If ISO 544 is invoked for technical delivery conditions, state its agreed edition and the applicable package designation. Still obtain the corresponding drawing. Keep the wire mass, loaded package mass and shipping mass separately identified in the quotation.
Check the proposed package against the exact feeder
Send the feeder model, spool-holder version and any approved adapter reference with the RFQ. Equipment manuals can list different spool limits for different versions within one product family. Check both the package envelope and the stated mass limit rather than transferring a limit from a similar-looking machine.
A basket package may need its own approved adapter. Have the equipment owner verify seating, retention, the locating feature and brake operation against the manufacturer’s instructions. Resolve any adapter requirement before accepting the package. Avoid treating an improvised fit as a confirmed interface.
Agree the feeding checks without inventing universal limits
Cast describes the natural loop diameter of released wire; helix describes its rise from a flat reference surface. These features can affect feeding and wire tracking. Agree any required limits and the measurement method against the ordered titanium filler specification and application. Values published for carbon-steel wire are not titanium acceptance limits.
Spool compatibility is only one part of the feeding arrangement. The equipment owner should also confirm rollers and the wire path for the selected diameter and material. Use the exact machine instructions for loading and adjustment. Package acceptance does not qualify a welding procedure or establish welding parameters.
Keep receiving checks tied to the package identity
Before opening, compare the package label, filler classification, diameter and lot identity with the order and certificate. Record damaged flanges, loose winding, a disturbed wire end or damaged protective packaging for review. Preserve the identity when an opened spool is stored or returned to service. Agree the handling of a suspect package with the responsible quality and welding personnel.
Send one complete spool-compatibility RFQ
- State the approved filler classification, specification edition, wire diameter and required quantity.
- Attach the supplier spool drawing or request it, including dimensional tolerances and package construction.
- Identify net wire mass, empty spool mass and loaded package mass.
- Provide the exact feeder, holder and adapter references, together with the required pay-off arrangement.
- Define any cast, helix, winding, cleanliness, marking and inspection-document requirements.
Please confirm the proposed titanium welding wire package against the attached feeder and holder information. Provide the spool drawing, dimensional tolerances, net wire and loaded package masses, adapter requirements and lot identification. Identify any mismatch for review before shipment.
For a procedure requiring that classification, the ERTi-2 titanium welding wire page provides the material and documentation enquiry route. Send the package drawing and equipment references with the request so the proposed supply can be reviewed against the order.
