Abstract
A method of flash butt welding high-carbon materials, in particular nodular cast iron wherein the arcing craters produced by intermitting contact of the contact faces have a maximum roughness depth R.sub.T such that this roughness depth lies within the narrowest thickness of the plasticized zone. As a result, when the upsetting pressure is applied, the entire molten material areas on the contact faces are pressed out of the contact faces into the welding bead thereby prohibiting the creation of hardening structures, such as, for example, ledeburite in the welding zone. The method is especially suitable for flash butt welding workpieces having wall thicknesses of over 12 mm.
