Abstract
The process comprises welding, based on heating of circular or oval rods, by means of electric current, with differential cooling along their length. Thus air is blown from various nozzles, and then axial force is applied to fracture, giving two constant conicity prongs. The rods advanced by a feeder have a cutter and tensioning jaws also carrying the current. The axial force is applied hydraulically.
