Abstract

The machine consists of a pair of frames separated by a flywheel system mounted on a mobile base such as the tracks of a crawler tractor. The sections of pipe to be joined are firmly held by chucks, one in each frame and another short section of pipe is held inside the flywheel system so that it can turn. When the flywheel is rotated by means of a motor and then disengaged by means of a clutch mechanism, the ends of the two sections of pipe are brought into contact with each end of the short pipe section which each they become welded. The machine may be used on site.
