The main advantages of butt welding machine:
1. Energy saving. The radiator flash butt welding machine uses two 125KVA welding resistance transformers as power sources, pneumatic pressing, upsetting, and no hydraulic station. Compared with other single-phase AC welding resistance transformers of 315KVA, two sets of 315KVA are used. And two welding machines with a power of 18KVA hydraulic station, UN-250AB welding machine can save up to 78℅.
2. The requirements for the power grid are low. Only a 250KVA power grid can be satisfied.
3. High welding precision. Using programmable controller PLC and inlet stepping motor to control the flashing process, the burning amount and burning speed can be accurately set, and the welding current is controlled by the microcomputer welding resistance controller. The center distance error of the film head after welding It can be controlled within ±0.2mm, which is convenient for subsequent assembly and welding.
4. Automatic centering function. Ensure that the distance between the two ends of the pipe string and the two film heads is the same before welding, so as to ensure the same amount of burning at both ends.
5. High welding efficiency. Because the workpiece is pressed by the double force cylinder, its reaction speed is significantly faster than that of the hydraulic cylinder.
6. It is convenient to operate and maintain. Because there is no hydraulic station, the debugging points and fault points of the product should be less, and there will be no oil leakage.
