H3660-Y series T&MD Dual System Automatic Welding Machine
Automatic WelderDN50 – DN600
The H3660-Y series is a dual-process TIG/MIG welding machine built for automatic pipe, elbow, tee, and flange fabrication, pairing a 360 mm spindle-bore, three-jaw self-centering electric chuck with axially movable clamping for front- and rear-side welds across three sizes spanning 1000-3000 mm of chuck-forward travel. A manipulator arm, full-angle positioner, and adjustable torch head give multi-position, multi-angle reach, while standard AVC arc tracking and cross-oscillation hold the seam. A touchscreen HMI stores 30 WPS presets, and one-touch automation runs butt and fillet joints in carbon steel, low-alloy steel, and stainless steel.

Product Details
Wide Joint & Material Application Range
- Butt Welding Versatility: Handles pipe-to-pipe, pipe-to-elbow, pipe-to-tee, and pipe-to-welding-neck-flange butt joints in a single automated setup.
- Fillet Welding Capability: Also completes fillet welds on pipe flanges and elbow flanges, with an optional longitudinal-seam function for tank and vessel shells.
- Multi-Material Compatibility: Welds carbon steel, low-alloy steel, stainless steel, and other common fabrication materials without retooling.
- Dual TIG/MIG Process Flexibility: Built-in TIG and MIG/GMAW equipment let one machine deliver TIG's weld quality or MIG's welding speed, whichever the job calls for.
Heavy-Duty Mechanical Positioning
- Precision Self-Centering Chuck: A standard three-jaw self-centering electric chuck with a 360 mm through-hole and Φ50–Φ600 mm clamping range keeps the workpiece accurately centered.
- Multi-Axis Torch Adjustability: A welding manipulator arm, full-angle positioner, and torch-angle adjustment mechanism combine for multi-position, multi-angle torch conversion on complex joints.
- Dual-End Chuck Welding: The chuck's axially movable, reliably locking design lets both its front and rear sides be welded, extending reach and adaptability.
Intelligent Control & Automation
- Intuitive Touchscreen HMI: A large color touchscreen HMI keeps programming straightforward for operators of any experience level.
- WPS Recipe Memory: Stores 30 welding-procedure sets (40 with the longitudinal-seam option), each recalled by ID to match the workpiece at hand.
- One-Touch & Manual Modes: One-touch operation runs the entire weld cycle automatically, while real-time manual intervention stays available whenever an operator needs to fine-tune parameters.
Advanced Process Control & Reliability
- Arc Tracking & Weaving: Standard AVC (arc voltage control) and a torch cross-oscillation (OSC) system keep the arc locked onto the seam through variation in the joint.
- CNC-Precision Wire Feeding: A CNC automatic wire feeder adds wire retraction and pulsed feed for consistently accurate deposition at 1.0 mm or 1.2 mm wire diameters.
- Forced Closed-Loop Cooling: A forced circulation water-cooling system supports continuous, long-duty-cycle operation without thermal derating.
