When welding, welding pressure, between two welding wheel spin welding wheel drives the weldment and electricity, welding current by welding and local heating, forming successively overlapping to form a continuous weld joint and realize the permanent welding.Light reaction for casing, such as automobile, motorcycle fuel tank; Barrel, such as cans, and sheet forming artifacts, such as wheels, seam welding of muffler, radiator, etc.

Adopt 200KVA resistance welding special transformer energy as welding power supply. Output current is above 34000A when the duty cycle rate is 25%. Executed standard is GB/15578-2008, magnetic permeability of forced temperature control water cooling silicon steel sheet is above 1200GS, special water cooling and subprime loop, ensuring constant and powerful welding current, providing guarantee for high quality welding spot.


Roll seam welding is widely applied to welding of differnt size of oil tanks, sealed container of oil drum, can, heating radiator, airplane and fuel tank, rocket and missile. Can customzied accoridng to your product size and requirement.


1. Adopt intelligent microcomputer single piece controller which achieve pure digital setting. Online computer programming, LED digital display, stable performance, convenient modification of the program online.

2. Adopt intelligent microcomputer control welding system. When the voltage fluctuates, it will compensate the welding current automatically to ensure the stability of welding.

3. Adopt digital circuit control; select the components from famous factories in the world to ensure the equipment could operate steadily in the long run.

4. Adopt SEMIKRON from West Germany, IXYS and IR silicon controlled from United States. High precision, long operating life, achieve high stability control of the magnitude of current.

5. The transmission tile axis adopts the latest mercury conductive technology from abroad. State-of –the-art technology with good performance in transmission and conductivity.

6. Welding roll wheel adopts the alloy copper material from Japan. High rigidity, good conductivity.

7. The transformer adopts the high pure silicon steel sheet from Japan, good performance in magnet and electricity conductivity. Low consumption of electricity. Stronger and more stable power.

8. Welding mold and the connection of the whole machine uses the mosaic connection. Easy to be assembled and disassembled.

9. AC pulse, secondary rectifying and three-phase medium frequency type of welding power source are available.
