[0002] In the construction of steel cages in the process of building construction, the steel cages involving circular beams and columns need to be welded with circular steel rings. Generally, steel bar butt welding machines are used. The methods of steel bar butt welding are generally friction butt welding, flash butt welding, and resistance welding. etc. Friction butt welding is to use one of the two workpieces to be welded to make a circular steel ring, and use friction to generate heat to shape and deform the contact position of the workpiece, and when the rotating workpiece stops instantaneously, the two Key welding, this method cannot be realized because the circular workpiece cannot be unilaterally rotated. Flash butt welding and resistance welding are generally suitable for small diameter workpieces, and the welding strength is relatively weak, and the effect is not good in the butt welding of large diameter circular workpieces
