Why Choose Inconel 617 Welding Wire

• Cobalt and molybdenum solid-solution strengthening deliver excellent creep-rupture strength above 800°C.
• High chromium plus aluminium form a protective oxide scale, giving outstanding oxidation and carburisation resistance to 1100°C.
• Retains metallurgical stability and ductility after long-term thermal exposure.
• Widely qualified for advanced ultra-supercritical (A-USC) power plant and gas turbine hot-section components.

Welding Best Practices

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

• Preheat is generally not required, but heavy sections benefit from 100–150°C to remove moisture.
• Maintain interpass temperature below 200°C (390°F) to limit grain growth in the HAZ.
• Use argon shielding with a trailing shield; the aluminium content makes the puddle sensitive to oxidation.
• For thick sections, use a controlled low heat input (0.8 – 1.8 kJ/mm) and multi-pass stringer technique.
