Why Choose Inconel 92 Welding Wire

• Manganese and niobium work together to give excellent resistance to hot cracking and microfissuring.
• Purpose-designed for dissimilar welding of nickel alloys to carbon and low-alloy steels.
• Tolerates high iron dilution from the steel side without forming brittle phases.
• Long-standing nuclear-qualified filler for reactor pressure vessel dissimilar metal welds.

Welding Best Practices

Follow these practical guidelines to obtain sound, corrosion-resistant welds with this filler metal:

• Apply a buttering layer on the steel side when dilution exceeds roughly 30%.
• Keep interpass temperature below 175°C (350°F); preheat carbon steel per its own procedure.
• Use DCEN polarity for GTAW with high-purity argon shielding.
• Peen or use low-restraint sequencing on highly restrained joints to relieve shrinkage stress.
