The prestressing tendon should be cut off by grinding wheel saw or cutting machine. Why can't arc cutting be adopted?
The reason is very simple, I do not say Theory: the temperature of welding is too high, so that steel annealing, and reduceStrength of reinforcement
Prestressed reinforcement is in the component has no load, the reinforced tension, if heated, reinforced soft, elongated, such as steel and loosened, no tension, no prestress, prestress loss.
Not to reduce the strength of the steel bar is to reduce the stress on the steel bar.
