Place of Origin:
40KVA Automatic Seam Welding Machine Welding Equipment for Welding Coffee Pot Base
The seam (roll) welding special machine is the evolution of spot welder. It uses the roller electrode to replace the cylindrical electrode of spot welding and as the welding work piece moves between the rolling plates, the seal welding will generate weld nuggets which will overlap with each other so as to achieve welding effect.
The weld seam of roll welding is composed of welding spots. According to different overlap of the melting cores, it could be divided into roll spot welding and air-tight seam welding. There exist three stages in the forming process of welding spots: pressurization, heating fusing and cooling crystallization like spot welding.
However, this kind of welding approach is greatly different from spot welding because the inevitable current shunt makes the current field and thermal field of weld zone distinctive. Moreover, the rolling plate that is used to transmit pressure and ohmic heating keeps rolling and changing the welding position which results in the features of the current field and thermal field distribution and the crystallization of fusion zone are related to the speed of changing position.
1. The transmission tile axis adopts the latest silver tile conductive technology from abroad. State-of –the-art technology with good performance in transmission and conductivity.
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. Welding roll wheel adopts the alloy copper material from Japan. High rigidity, good conductivity.
