Vertical Round Duct Seam Welding Machine Easy Operation Roller Welder for HVAC Production

Product Description

Product Description

The Automatic Round Duct Welding Machine is an advanced welding solution that integrates automatic centering, rotation, welding, and cooling functions. It is specially designed for circumferential welding of metal pipes, stainless steel ducts, and ventilation components.
Controlled by a servo motor and PLC system, it ensures fully automated operation with precise positioning, uniform welds, and easy operation. It is widely used in industries such as HVAC ducting, automotive parts, stainless steel containers, and household appliances.

Key Features:
 •  High Automation: Integrates feeding, clamping, rotation, welding, and cooling for continuous production.
 • Excellent Welding Accuracy: Servo-driven system ensures smooth, uniform weld seams without deviation.
 • Advanced Control System: PLC with touch screen interface allows parameter setting and real-time monitoring.
 • Efficient Cooling: Built-in water cooling system prevents overheating and maintains welding quality.
 • Easy Maintenance & Safety: Compact structure with emergency stop and overload protection ensures reliable operation.

Air Filter & Lubrication Unit

Removes moisture and oil impurities from compressed air, effectively protecting pneumatic components (such as air clamps) from contamination and wear. Regular drainage and lubrication are recommended to maintain long-term system stability.

Control Panel

Equipped with a PLC control system and touch screen/keypad interface for setting welding parameters (speed, current, time, etc.) and managing machine operations. The panel serves as the operational core of the system, offering user-friendly interaction, multilingual support, and real-time status monitoring.

Water Cooling Tank

An essential part of the cooling system, the water tank provides continuous cooling to welding components (such as copper pads and electrodes), preventing overheating and deformation to ensure welding accuracy and quality.

Transmission System

Drives the rotation and movement of pipes or welding torches to ensure precise positioning and smooth operation. Widely used in circular seam welding and automatic welding systems, it offers high reliability and durability.

Copper Welding Head

Made of high-conductivity copper for superior electrical and thermal performance, efficiently transmitting welding current and ensuring precise seam alignment. Compact in structure, durable, and easy to maintain.
