Seam welding is a kind of metal welding that forms a permanent combination, when welding, the weldment deposit is between the two welding wheels, the welding wheel is rotated to drive the weldment and energized, the welding current is heated by the weldment locally, forming a continuous weld that overlaps successively to form a continuous weld, to achieve permanent links, widely used in the box: such as automobile motorcycle fuel tank, barrel body: such as steel drum, and the formation of plate workpieces, such as wheel rim silence / radiator and so on.
The seam welding machine is usually composed of frame, pressurized structure, weld wheel (electrode), welding power supply, speed regulation transmission mechanism and controller.
1: Pressurization mechanism: transmit pressure, uniformly adjust the pressure between the welding wheels and compensate for electrode wear,
2: Welding wheel: using internal external water cooling, conductive block using pure silver tile structure, good conductivity and automatic compensation of wear function,
3: speed regulation transmission mechanism: the use of frequency conversion speed regulation gear reducer transmission,
4: Seam welding machine has two forms of longitudinal seam welding and cross seam welding, which is suitable for various workpiece welding needs.
