Zfh-25 automatic parallel seam welding machine is anautomatic equipment, which is mainly composed of automaticfeeding mechanism, prewelding system, Y seam welding head, Yseam welding head,Xseam welding head,Xseam welding head,transmission mechanism, automatic feeding mechanism, nitrogenprotective atmosphere glove box, support, vacuum oven. Theequipment can precisely position ceramic metallized base or metalbase and cover plate and spot welding and seam welding. Theequipment is controlled by ipc and vision positioning system, with fastdynamic response and high control accuracy. n addition, the wholemotion mechanism is placed in the glove box of nitrogen atmosphere,which can improve the welding effect.
