| 主权项 | 1. A method of preparing a pipe for joining to another pipe, the method including the steps of: fixing a cutting tool to a second side of a fusion welding machine; fixing a first pipe to a first side of the fusion welding machine such that a longitudinal axis extending through the first pipe extends through the cutting tool; and moving the cutting tool along the longitudinal axis so that the cutting tool engages an internal wall of the first pipe to thereby cut the internal wall of the first pipe and reduce a wall thickness of the first pipe, preparing the first pipe for joining to a second pipe; wherein the fusion welding machine comprises: a holder for fixing the second pipe to the second side of the fusion welding machine; a heater for heating ends of both the first pipe and the second pipe; and a drive for moving the first pipe with respect to the second pipe. | ||
