Single-End Heat Pipe Automatic Welding Machine

Feihong offers the Single-End Heat Pipe Automatic Welding Machine, a specialized resistance welding system engineered for sealing the bottom end of single-hair heat pipes. As a trusted China supplier with over 30 years of manufacturing experience, Feihong combines capacitor discharge spot welding technology with pneumatic manipulator control to ensure precise, repeatable welds. The machine operates at 5KVA power, 380V voltage, and 0.6Mpa air source, with manual loading and unloading. The equipment's swing cylinder and vacuum attachment system work together to position the workpiece accurately in the alignment groove before welding, minimizing misalignment and ensuring consistent joint quality across production runs.

Single-End Welding Design

This welding equipment is purpose‑built for single‑end closure of heat pipes, a critical operation in the manufacturing of electrical heating elements. Unlike general‑purpose welders, this machine incorporates a dedicated positioning system that aligns the bottom end of the heat pipe precisely with the welding electrodes. The capacitor energy storage system delivers a controlled high‑current pulse specifically calibrated for thin‑wall tube sealing, ensuring complete penetration without burn‑through.

Design features that support single‑end welding include:

1. Dedicated positioning groove – Precisely locates the heat pipe bottom for accurate electrode contact.

2. Vacuum attachment system – Holds the welding piece securely against the station during discharge.

3. Optimized capacitor bank – Energy output tailored for consistent single‑end closure welding.

4. Pneumatic swing cylinder – Transfers the workpiece smoothly to the welding position with minimal handling.

This single‑end focus allows the Single-End Heat Pipe Automatic Welding Machine to deliver superior weld quality compared to multi‑purpose equipment, with reduced setup time and fewer rejected parts.

Vibratory Feeding Integration

The machine incorporates an electromagnetic vibrating disc feeder that automatically orients and delivers components to the welding station. This feeder system, combined with the pneumatic manipulator, streamlines the material flow and reduces manual handling steps. The vibratory disc is adjustable for feed rate and orientation, accommodating different heat pipe lengths and diameters while maintaining consistent part presentation to the welding station.

Feeding system capabilities include:

● Electromagnetic vibration for smooth, jam‑free part flow.

● Adjustable amplitude and frequency to match production speed.

● Integrated vacuum pickup that secures the part during transfer.

● Quick‑change positioning grooves for product changeovers.

This integration makes the welding process more efficient for heat pipe assembly lines with medium to high production volumes.
