TB-65 Tube to Tube Sheet Welding Head

The KEPUNI TB-65 is a specialized welding head engineered for all-position orbital welding of tube-to-tube sheet joints, ensuring precise, repeatable welds across diverse industrial applications.

Key Specifications:

Pipe Diameter Range: 8 mm – 63 mm

Joint Type: Butt welding configuration

Wall Thickness: 0.5 mm – 5 mm

Advanced Features:

Pneumatic Core Expansion Alignment
A pneumatic mechanism automatically centers and clamps the welding torch within the tube fitting, eliminating manual alignment errors
Supports tube extension, leveling, autogenous fusion (no filler), and wire-fill welding, adapting to varied joint geometries and material requirements.

Compact, Integrated Design
Features internal water/electricity routing with a 360° conduit-free workspace, minimizing maintenance and enhancing operational safety.

One-Button Pneumatic Actuation
A single-button control expands the copper sleeve to secure the torch, enabling rapid repositioning during multi-joint welding sequences.

Precision Control Systems
Arc Length Controller: Maintains ±0.1 mm arc stability for consistent penetration and bead quality.
Yaw Control Device: Adjusts torch angle dynamically to compensate for tube misalignment.
Water-Cooled Torch: Sustains a 100% duty cycle at 300A, preventing overheating during extended welds.

Applications:

Power Generation: Welds boiler tubes, heat exchangers, and steam generators.

Petrochemical: Repairs process piping and reactor vessels.

HVAC: Fabricates chiller coils and condenser tubes.
