1. Fully automatic orbital TIG welding for consistent joints
The equipment uses a mechanically rotated arc that orbits 360° around a stationary tube, eliminating human variables such as arc length drift and uneven travel speed. Every weld delivers consistent penetration, bead profile, and heat input, significantly improving first-pass yield.

2. Versatile joint configuration support
Supports flush, protruding, and recessed tube-to-tubesheet joint types. Capable of both autogenous (fusion-only) and filler-wire welding, making it adaptable to various manufacturing requirements across boilers, heat exchangers, and pressure vessels.

3. Wide tube diameter and material coverage
Handles tube diameters from 12 mm to 80 mm. Compatible with carbon steel, stainless steel, chrome-moly alloys, nickel-based alloys, and titanium—meeting the needs of applications ranging from industrial boilers to nuclear-grade equipment.

4. Water-cooled system for continuous production
The welding head features an integrated water‑cooling circuit, ensuring stable temperature during high-current, extended operation. High duty cycle supports 24/7 production with minimal downtime for cooling.

5. Precision centering and quick tooling
Utilizes expanding mandrels and a three‑point support structure for precise centering on the tube ID. Multi‑axis adjustment (radial, axial, and angular) enables fast setup and short cycle times. One operator can manage multiple welding heads simultaneously.

6. Programmable parameters for batch production
Equipped with a digital control system that stores welding schedules—current, pulse frequency, rotation speed, wire feed rate, and more. Approved parameters can be recalled with one touch, ensuring consistent weld quality across production batches.
