HALDEN Pipe Inner Wall Weld Overlay Cladding Solution
Automatic TIG Hot Wire Pipe Inner Wall Cladding Machine for Long Tube Weld Overlay
HALDEN automatic TIG hot wire pipe inner wall cladding machines are designed for corrosion-resistant weld overlay inside long pipes, seamless tubes, forged tubes and pressure-related pipe components. The system combines TIG welding quality, hot wire deposition efficiency, automatic arc voltage control, pipe rotation and long-reach welding torch guidance to produce stable internal overlay layers for oil and gas, chemical, valve, pressure vessel and pipeline industries.
What Is a Pipe Inner Wall Cladding Machine?
A pipe inner wall cladding machine is an automated weld overlay system used to deposit corrosion-resistant or wear-resistant alloy layers on the internal surface of long pipes and tubes. Instead of manufacturing the entire pipe from expensive alloy material, the base pipe can be made from carbon steel or low-alloy steel, while the internal surface receives a high-performance alloy overlay.
For long pipe applications, the machine must solve several practical problems at the same time: long torch reach, stable pipe rotation, accurate arc length control, reliable wire feeding, weld pool visibility, water-cooled torch protection and consistent layer-by-layer overlay quality.
Long Pipe Capability
Designed for internal cladding of long tubes and pipes up to 12,000mm reference length.
Hot Wire TIG Quality
Combines GTAW weld cleanliness with higher deposition efficiency from hot wire feeding.
Low-Dilution Overlay
Suitable for corrosion-resistant alloy cladding where final chemistry and dilution control matter.
100% Inspection Ready
Designed for demanding quality requirements such as 100% UT layering and 100% PT inspection.
HALDEN Long Tube Inner Wall TIG Hot Wire Cladding System
The system is designed for long tube inner wall anti-corrosion welding. The base tube is driven and rotated by a hollow chuck. The welding torch is positioned and guided into the pipe by a long-reach torch mechanism, wire rope pull system and guide equipment. During welding, the torch remains stable while the pipe rotates in 1G position.
This configuration is especially useful for pipe manufacturers, oilfield equipment suppliers, pressure component fabricators and corrosion-resistant piping projects where long internal surfaces require uniform alloy overlay.
Hollow Chuck Pipe Rotation
The pipe is driven by the end hollow chuck, while the welding gun stays in position for stable 1G internal cladding.
Long-Reach Welding Torch
A long torch system supports internal cladding of pipe lengths up to 12.5m reference capability.
AVC Arc Voltage Control
Automatic arc pressure / arc voltage tracking helps correct torch distance and stabilize bead formation.

Quality Control for Pipe Inner Wall Cladding
For pipe internal weld overlay, buyers normally care about final alloy chemistry, thickness, dilution, surface defects, interlayer quality and inspection pass rate. Long pipe cladding also requires stable monitoring because the welding position is inside the pipe and cannot be inspected visually like an external weld.
100% UT Layering
Layer-by-layer ultrasonic testing can be required to verify internal soundness and overlay integrity.
100% PT
Liquid penetrant testing helps detect surface-breaking defects after cladding and machining.
AVC Stability
Arc voltage control helps maintain consistent torch distance and bead shape during long bore cladding.
Water-Cooled Torch
Forced circulating water cooling protects the welding gun during long-duration continuous welding.
Camera Monitoring
A water-cooled weld camera allows the operator to monitor internal overlay quality during production.
