Product Introduction:
Features:
1.Dedicated Welding Workstation: Circumferential duct welding is concentrated within a specialized machine, reducing variations caused by different manual working environments.
2.Consistent Welding Movement: The main welding action is performed through a fixed electrode mechanism, creating a more standardized process.
3.Defined Workpiece Rotation: The operator rotates the duct so that the circular seam passes through the welding area.
4.Reduced Complex Manual Welding Movement: The operator does not need to continuously move a welding torch around the entire circumference.
5.Suitable for Batch Processing: Manufacturers repeatedly producing similar ducts can use the machine as a dedicated welding stage.
6.Easy Production-Line Integration: The machine can be positioned between duct forming, assembly and subsequent processes as a clearly defined production station.
Welding Test:



Welding Workpiece: Suitable for stainless steel ducts, straight tubes, reducers, elbows and other cylindrical workpieces with circumferential seams.
Detailed Images:

Upper & Lower Electrode Wheels: The upper and lower copper electrode wheels form the main welding contact area as the duct rotates through the welding position.

Upper Pneumatic Actuator: The top pneumatic cylinder drives the welding assembly vertically and provides the required movement for the upper electrode wheel.

Gas Storage Tanks: Stores and buffers compressed air to provide a stable air supply for the pneumatic system.

Water Circuit Components: Equipped with flow monitors, water pipes, valves and fittings for monitoring and controlling the cooling water circulation.

Multi Types of Seam Welders:
Ring Seam Welding Machine
The seam welding machine is designed for circumferential seam welding of corrugated stainless steel pipe fittings, widely used in appliance connectors such as dishwashers and washing machines. It features automatic clamping and rotary welding, offering stable welding, easy operation, and efficient performance for continuous mass production.
Automatic Filter Drum Longitudinal Seam Welding Machine
The seam welding machine is designed for automatic rolling and longitudinal seam welding of low-carbon steel filter drums. Suitable for 0.5–1.5 mm steel sheets, it features pneumatic pressurization and servo-driven roller welding for stable, efficient, and automated production.
Horizontal Automatic Seam Welding Machine
The seam welder is mainly designed for welding shock absorbers or piston cylinder tubes. It is an automatic welding equipment used for welding circular and annular welds, widely used for welding various metal materials with sealing requirements, including stainless steel, low-alloy steel, aluminum, iron, and other alloys. It mainly completes welding by rotating the electrode to drive the workpiece to rotate.
FAQ:
1. When can you arrange shippment?
The shippment is 15 days after getting deopsit, but customized machines should be more than 25 days.
