The main advantages of butt welding machine:
1. Energy saving. The radiator flash butt welding machine uses two 125KVA welding resistance transformers as the power supply, pneumatic compression, upsetting, and no hydraulic station. Compared with other single-phase AC welding resistance transformers using two 315KVA And two welding machines with a power of 18KVA hydraulic station, the UN-250AB welding machine can save electricity up to 78℅.
2. Low requirements on the power grid. Only 250KVA power grid is enough.
3. High welding precision. Programmable controller PLC and imported stepping motor are used to control the flashing process, which can accurately set the burning amount and burning speed, and control the welding current through the microcomputer resistance welding controller. The center distance error of the chip head after welding It can be controlled within ±0.2mm, which is convenient for subsequent chip welding.
4. Automatic centering function. Ensure that the distance between the two ends of the pipe string and the ends of the two pieces before welding is consistent, so as to ensure the same amount of burning at both ends
5. The welding efficiency is high. Because the workpiece is pressed with a double force cylinder, its reaction speed is significantly faster than that of the hydraulic cylinder.
6. The operation and maintenance service is convenient. Because there is no hydraulic station, there are fewer debugging points and failure points of the product, and there will be no oil leakage and other phenomena.
