Titanium Welding Wire AWS A5.16 Supplier | ERTi-1 / ERTi-2 / ERTi-5 / ERTi-7 / ERTi-23, TIG & MIG, MTC 3.1

Meta Description: AWS A5.16 titanium welding wire supplier in Baoji — ERTi-1/2/5/7/23, TIG straight rod + MIG spool, bright-pickled, argon-clean, EN 10204 3.1 with measured interstitials. Classification + revision + lot on every spool. Lot confirmed before PI.

Overview — AWS A5.16 Is the Identity, Not a Buzzword

AWS A5.16 is the filler-metal spec for titanium arc welding (GTAW/GMAW/PAW). It does three things a "Gr1 wire" label cannot:

• Fixes the ERTi-X classification (filler, not base wire)
• Caps interstitials (O/N/H/C) by class — the real driver of weld ductility
• Requires identification: AWS class + manufacturer + size + lot/heat on every spool/rod unit

ASTM B863 is for non-welding wire (springs, fasteners, mesh). Same metal, different job. A code weld citing AWS A5.16 / D1.9 cannot be released on a B863 cert alone — the filler classification must be named. We supply both, but the PO decides which cert line ships.

ERTi Class Quick Selector

Full chemistry bands per AWS A5.16 (rev stated on PO). MTC lists measured O/H/N/C — not "complies".

Forms & Sizes (AWS A5.16 Route)

Custom wind to feeder model on request — tell us push / pull / dual, we layer-wind to match.

Why Interstitials Decide the Weld

• Oxygen: raises strength, kills ductility. Blue/grey bead = pickup, not cosmetic.
• Hydrogen: delayed cracking risk; vacuum anneal + sealed pack matter.
• Nitrogen: nitride skin, hard/brittle — purge must hold to cool.
• Carbon: carbide stringers hurt fatigue.

AWS A5.16 exists largely to police these four. Wire surface must be pickled/bright, oil-free, no drawing lube — argon-clean on arrival, kept sealed until the feeder.

Mechanical Reference (Deposit / Base Min.)

Final joint properties = wire lot + your WPS/PQR + purge discipline. Wire alone doesn't make the weld pass.

Identification & Traceability (AWS A5.16 + EN 10204 3.1)

• Every spool/rod unit tagged: AWS class + manufacturer ID + Ø + lot/heat No.
• EN 10204 3.1, mill-authorized IR: measured chemistry (interstitials called out) + tensile + lot-to-ingot
• Sealed cert pouch: MTC + (UT/cleanliness report per PO)
• 3.2 (SGS/BV/TÜV) witness PO-fronted, not back-signed
• ERTi (filler) and B863 (base wire) never mixed on one cert line

Packaging Non-Negotiables

• Vacuum foil + desiccant + aluminium barrier
• D200/D300 plastic spool, no steel contact
• TIG rods: PE/kraft tube, ends capped, flag tag per rod
• Outer: plywood case / antistatic carton, "DRY / NO OIL / ARGON-CLEAN"
• Pre-ship photo: spool face + lot tag + seal

WPS Compliance — What We Confirm Before PI

1. AWS A5.16 revision (latest cited on PO)
2. ERTi class matched to base metal + WPS
3. Ø + process (TIG/MIG/PAW) + spool type
4. Interstitial ceiling (O/H/N) if tighter than class default
5. Shielding note (Ar purity, back purge) — printer-side, but we align pack to it
6. Cert type (3.1 default / 3.2 TPI named)

No "A5.16-compatible" vague stamp. Either the PO names the class, or we qualify it with you before dispatch.

Stock Scope (Honest)

No "all classes same-day". Lot confirmed → PI date = dispatch commitment.

FAQ — AWS A5.16 Titanium Welding Wire

Q1: AWS A5.16 vs ASTM B863 — which cert do I need?
A: Welding filler → AWS A5.16 (ERTi class). Springs/fasteners/mesh → ASTM B863. Code welds cite A5.16; B863 alone won't clear QA on a WPS.

Q2: Can ERTi-2 weld Gr5 base?
A: Feedable, ductile, but understrength vs Gr5. Match ERTi-5 unless the welding engineer approves undermatching in the WPS.

Q3: Is "Gr5 wire" the same as ERTi-5?
A: Not on paper. ERTi-5 is the A5.16 filler classification with interstitial bands. PO must say ERTi-5 + revision.

Q4: Blue bead — wire fault?
A: Usually purge/contamination, not chemistry. Wire ships argon-clean; chamber/argon dewpoint is printer-side.

Q5: MTC real numbers?
A: Yes — measured O/H/N/C/Fe + tensile + lot. Not minima-only.

Q6: STA ERTi-5 from shelf?
A: No. Annealed default. STA = PO-stated heat treat + re-MTC.

Q7: Medical implant weld?
A: ERTi-23 ELI + F136/ISO 5832-3 chain, separate PO, clean-pack. Industrial ERTi-5 ≠ implant.

Q8: Spool tangle?
A: Precision layer-wind to feeder type. State push/pull/dual at enquiry.

Q9: Custom diameter / D300+?
A: PO-fronted, melt schedule quoted before PI. Core sizes move same-week after lot confirm.

Q10: Quote time?
A: 24h with class + Ø + form + qty + incoterm. Lot status confirmed before PI.
