Abstract
The invention relates to a machine for butting two metal bands (M , M ) and a method for implementing such a machine. According to the invention, two successive bands (M , M ) are welded according to either one of at least two different welding modes, for example flash butt welding and laser welding. To this effect, two clamping jaw assemblies are available, suitable respectively to each welding mode and, when changing welding mode, the first jaw assembly ( ) used previously for welding is removed from the machine (S) and replaced with the second jaw assembly ( ) suitable to the second welding mode. During this operation, the jaws remain spaced apart so that replacement can take place as the first band unwinds to an end, before the running has stopped.
