nickel rod for Welding, Ready Stock Baoji | ERNi-1 TIG/MIG + ENi-1 Electrode for Nickel 200/201

Meta Description: Ready-stock nickel welding consumables from Baoji — ERNi-1 bare rod/wire (AWS A5.14, UNS N02061) for GTAW/GMAW/SAW, ENi-1 (AWS A5.11) coated electrodes for SMAW, matched to Nickel 200 (N02200) / 201 (N02201). Caustic duty, heat-number traceability, EN 10204 3.1.

Rod vs Filler — Say It Once, Correctly

• Base metal rod/bar: Nickel 200 = UNS N02200, Nickel 201 = UNS N02201 (ASTM B160 / SB-160)
• Matching bare filler (TIG/MIG): ERNi-1, AWS A5.14 / ASME SFA-5.14, UNS N02061
• Matching coated electrode (SMAW): ENi-1, AWS A5.11
• ERNi-1 is NOT N02200 — it carries 2-3.5% Ti to tie up free carbon and control porosity; deposit Ni ≥93%
• Do not substitute 308L/316L stainless filler on pure nickel — wrong system, hot-crack risk

Why ERNi-1 for Caustic Plants

• Matches corrosion behavior of N02200/N02201 in NaOH/KOH
• Ti deoxidizes weld pool → low porosity, sound root pass
• Low free-carbon deposit → compatible with low-carbon 201 base (no graphite embrittlement path)
• Joins nickel-to-nickel, nickel-to-carbon steel, stainless, Monel, Cu-Ni (transition/buffer layer)
• No preheat needed; PWHT usually not mandatory unless WPS calls for stress relief

The 315°C Rule (written on every quote)

• Base metal ≤315°C → Nickel 200 (N02200) + ERNi-1
• Base metal >315°C (hot caustic evaporator) → Nickel 201 (N02201) + ERNi-1, low-carbon route
• Welding heat cycle can push 200 into graphitization risk — high-temp service defaults to 201 base + ERNi-1

Welding Discipline (shop floor reality)

1. Mechanically clean + acetone/degrease; no sulfur, lead, oil, copper residue
2. 100% argon backing on root pass (GTAW)
3. Interpass ≤150°C (complex parts ≤100°C)
4. No oxy-acetylene welding (carburization)
5. No stainless brush — nickel-dedicated tools only, prevent iron contamination
6. Post-weld: pickle if heat tint present; light stress relief 550-650°C on high-restraint joints per WPS

QC / Docs With Every Lot

• EN 10204 3.1 MTC — heat number, chemistry, all-weld-metal tensile
• Lot ID per AWS A5.02 / SFA-5.02 (spool-to-heat traceability)
• PMI spot on bare rod; diameter laser gauge 100%
• Sealed anti-moisture pack (electrodes baked/conditioned per class)
• 3.2 (SGS/BV/TÜV) TPI PO-fronted, not back-built
• Dual cert AWS A5.14 + ISO 18274 available

FAQ — Nickel Welding Rod, Ready Stock

Q1: Is ERNi-1 the same as Nickel 200?
A: No. N02200 is base metal; ERNi-1 (N02061) is the filler, with Ti added. Same corrosion family, different UNS — MTC states both clearly.

Q2: Can I use 316L wire on nickel?
A: No. Wrong alloy system — hot cracking, loss of caustic resistance. Pure nickel needs pure-nickel filler (ERNi-1 / ENi-1).

Q3: TIG or MIG for field repair?
A: TIG (ERNi-1 straight rod) for root + precision; MIG for production runs. Both 100% argon shield.

Q4: 200 base or 201 base for my evaporator?
A: ≤315°C → 200; >315°C → 201 base + ERNi-1. We flag grade before pricing.

Q5: Electrode storage?
A: ENi-1 packs sealed; re-condition per AWS class if moisture-exposed — never weld from a damp pack.

Q6: Small maintenance qty OK?
A: Yes — 5 kg TIG tube or single spool handled, not ton-only.

Q7: MTC with consumable?
A: EN 10204 3.1 every lot; heat-to-spool traceable. 3.2 TPI PO-fronted.

Q8: Dissimilar joint (Ni to CS)?
A: ERNi-1 buffer layer is the standard route; WPS/PQR must qualify F-No.41 filler per ASME IX.

Q9: HS code?
A: Nickel welding consumable base 7505.22 / 7505.11 band — Broker confirms by destination.

Q10: Biggest mistake buyers make?
A: Buying "pure nickel rod" without UNS on the cert — if the MTC doesn't show N02061 (filler) or N02200/201 (base), reject it.
