Precision orbital TIG welding solution for thin-wall tube fabrication. Designed for clean, stable and repeatable tube-to-tube welding applications.
Precision welding heads for demanding tube applications
The HUAHENG TC Series orbital welding heads are developed for high-quality thin-wall tube welding applications where weld consistency, cleanliness and repeatability are critical.
With precision rotation control, sealed shielding chamber, water cooling system and quick auto-centering fixture, the TC Series provides stable orbital TIG welding performance for stainless steel, carbon steel, titanium alloy and copper tubes.
High-resolution encoder control ensures smooth rotation movement and consistent welding results.
Optimized argon protection design provides clean and stable weld appearance.
Fast positioning structure improves setup efficiency and welding repeatability.
Circulating water cooling supports stable operation during continuous welding.
Suitable for stainless steel, carbon steel, titanium alloy and copper tube welding.
Compact mechanical structure improves handling and field operation convenience.
