Welding Tips For Cu-Ni Commercial Pipe Fittings
Clean Before You Weld
Degrease and wire-brush the joint – no preheat needed for Cu-Ni
Use ERCuNi Filler
AWS A5.7 / ASME SFA-5.7 ERCuNi matches 90/10 & 70/30 alike
Shield With Argon
Pure Argon or Ar-He for GTAW; avoid oxygen-bearing gases
Keep A Short Arc
Tight arc length maintains shielding and cuts porosity
DCEN Polarity
Direct current electrode negative for GTAW root and fill passes
Back-Purge The Root
Argon back purge on pipe welds prevents root oxidation & sugaring

Tooling Recommendation
- Sharp, positive-rake carbide
- Uncoated or PVD-coated tips
- Slow, steady feed rate
Cutting Fluid
- Flood coolant recommended
- Prevents work-hardening & galling
- Improves surface finish
