Q1: What is Inconel 718 welding wire (UNS N07718)?
A1: Inconel 718 wire is a precipitation-hardenable nickel-chromium alloy with high strength, corrosion resistance, and good weldability. It is widely used for welding components in aerospace, gas turbines, nuclear reactors, and oil & gas equipment.
Q2: How does Alloy 625 (UNS N06625) wire differ from Alloy 718?
A2: Alloy 625 wire has excellent corrosion resistance and outstanding fatigue and thermal fatigue strength, making it ideal for marine, chemical, and offshore applications. Alloy 718, on the other hand, is designed for higher mechanical strength and creep resistance at elevated temperatures, particularly in aerospace and turbine uses.
Q3: What other nickel alloys are available in ESAB filler wire series?
A3: Besides Inconel 625 and 718, ESAB supplies nickel alloy filler wires such as Inconel 600, 601, and X-750, as well as Incoloy grades. Each alloy is formulated for specific applications ranging from high-temperature oxidation resistance to excellent corrosion protection in aggressive chemical environments.
Q4: What welding processes are supported by these filler wires?
A4: These nickel alloy wires are typically used in GTAW (TIG), GMAW (MIG), SAW (Submerged Arc Welding), and plasma arc welding processes, providing excellent arc stability, metallurgical compatibility, and high-quality weld deposits.
Q5: What factors determine the price of Inconel/Incoloy welding wires?
A5: Pricing depends on alloy grade (e.g., 625 vs 718), wire diameter, spool size, packaging type, order quantity, and fluctuations in raw material costs such as nickel, chromium, and molybdenum.
