Why Choose Inconel 82 Welding Wire

• The industry-standard filler for dissimilar welding between nickel alloys and carbon or stainless steels.
• Manganese and niobium provide strong resistance to hot cracking and weld metal microfissuring.
• Retains oxidation resistance and creep strength at elevated temperature.
• Extensively qualified for nuclear, petrochemical and power generation service.

Welding Best Practices

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

• Buttering the steel face is recommended when dilution is expected to exceed about 30%.
• Keep interpass temperature below 175°C (350°F); preheat only per the steel base-metal procedure.
• Use high-purity argon shielding with a gas lens; avoid excessive arc length.
• Remove oxides between passes with a dedicated stainless brush used only for nickel alloys.
