HALDEN Hot Wire TIG Weld Overlay Cladding Solution
Hot Wire TIG Weld Overlay Cladding System for Valves, Flanges, Pipes and Pressure Vessel Components
HALDEN hot wire TIG weld overlay cladding systems are designed for high-quality corrosion-resistant and wear-resistant overlay on internal bores, external surfaces, flat surfaces, valve bodies, flanges, pipe fittings, risers, nozzles and pressure vessel components. The system supports automatic TIG hot wire cladding with stable deposition, low dilution and repeatable quality for oil and gas, chemical, valve manufacturing and pressure equipment industries.
What Is a Hot Wire TIG Weld Overlay Cladding System?
A hot wire TIG weld overlay cladding system is an automated GTAW-based cladding machine that preheats the filler wire before it enters the weld pool. Compared with conventional cold wire TIG, hot wire TIG can improve deposition efficiency while maintaining high weld quality, clean weld appearance and low dilution.
This process is widely used when the base component requires a corrosion-resistant or wear-resistant alloy layer. Typical overlay materials include stainless steel wire, nickel-based alloy wire, cobalt-based alloy wire, duplex stainless wire, copper-nickel wire and selected wear-resistant welding wires.
Low Dilution
Designed to produce a controlled overlay layer with low base metal dilution for corrosion-resistant applications.
Automatic TIG Hot Wire
Combines TIG welding quality with hot wire deposition efficiency for precision cladding work.
Complex Geometry Cladding
Suitable for internal bores, flat surfaces, valve bodies, ring grooves and selected intersection surfaces.
Turnkey Automation
Can include welding power source, hot wire power, controller, HMI, turntable, servo axis and process programs.
HALDEN Vertical TIG Hot Wire Cladding Station
The vertical cladding station is designed for compact, powerful and automated overlay production. It is suitable for workpieces with different shapes and can be configured for internal surface cladding, external surface cladding, flat surface cladding and selected cross-bore or intersection cladding tasks.
For valve manufacturers, oil and gas equipment suppliers, chemical equipment manufacturers and pressure vessel fabricators, the key value is not only cladding thickness. The real value is stable dilution control, repeatable bead placement, qualified first-pass yield and reliable automation for difficult internal geometries.
Internal Bore Cladding
For valve bodies, flanges, nozzles, pipe fittings, risers and pressure vessel components requiring internal corrosion protection.
Flat Surface Cladding
For sealing surfaces, flange faces, wear surfaces and corrosion-resistant overlay areas.
Intersection Surface Cladding
Optional configurations can support 90-degree cross-hole intersection cladding, multi-bore intersection cladding and special geometry overlay.
