Abstract

Method of flash butt welding workpieces together, one of the workpieces is rectilinearly oscillated along the line of bringing the workpieces together. The oscillatory motion has an amplitude in the movement towards the other workpiece greater than the amplitude in the opposite movement Voltage is applied to the workpieces for flashing and heating them in the movement of bringing them together. An upset force is then applied to the workpieces. Whatever the variations in flashing speed, the spacing of the workpiece end faces at the moment of max. separation remains constant. This minimises passes and permits max. utilisation of the heating effect of current to raise welding productivity and butt-welding machine efficiency.
