HALDEN Inconel Weld Overlay & TIG Hot Wire Cladding Solution
Outer Pipe Inconel Weld Overlay Machine for Valves, Flanges, Pipe Rings and Pressure Components
HALDEN outer pipe Inconel weld overlay machines are designed for automatic TIG hot wire cladding on corrosion-resistant and wear-resistant surfaces. The system can be used for external surfaces, internal bores, flat surfaces, ring grooves, valve bodies, flanges, pipe rings, risers, nozzles and pressure vessel components. It is especially suitable for oil and gas, chemical, valve manufacturing and pressure equipment industries where low dilution, stable alloy chemistry and repeatable cladding quality are critical.
What Is an Outer Pipe Inconel Weld Overlay Machine?
An outer pipe Inconel weld overlay machine is an automated cladding system used to deposit a nickel-based alloy layer on the surface of carbon steel, low-alloy steel, stainless steel or forged components. Instead of making the whole part from expensive Inconel or nickel alloy, the base component keeps its mechanical strength and cost advantage, while the surface receives a corrosion-resistant or wear-resistant alloy overlay.
For many oil and gas, valve and pressure equipment applications, the final overlay must meet strict requirements for dilution, chemistry, thickness, bonding quality and surface defect control. Automatic TIG hot wire cladding is widely used because it combines clean GTAW weld quality with higher deposition efficiency than cold wire TIG.

Suitable for ERNiCrMo-3, ERNiFeCr-1, ERNi1 and other nickel alloy wires for severe corrosion service.
Automatic TIG Hot Wire
Preheated filler wire improves deposition efficiency while maintaining TIG weld cleanliness and process control.
