Abstract
PURPOSE: To make stable flash butt welding of high quality possible by measuring the quantity of heat for flash charging to be applied to flash welding articles, and controlling flash voltage and the feed of a moving table in such a manner that this quantity of heat is kept constant.
CONSTITUTION: The end face of an object 2 to be welded grasped by moving side electrodes 5, 6 under pressing force P is collided against the end face of an object 1 to be welded grasped by stationary side electrodes 3, 4, under pressing force P at a velocity V by the movement of a moving frame 8 directly coupled to a driving device 9. Flash is generated between the end faces of the objects 1, 2 by the flash current I2 generated by this collision. Further, the object 2 is repeatedly moved at the velocity V, so that the end faces of the objects 1, 2 are melted and welded by pressure. During this time, the quantity of heat for flash charging is detected 22, and is compared with the set reference quantity of heat having beforehand set 23 depending upon the quantities and sectional areas of the materials 1, 2. The result of the comparison thereof is fed back to the feed control for the moving table, and the speed of the frame 8 is so controlled by the device that the quantity of heat for flash charging and the reference quantity of heat are kept always equqal.
