ABSTRACT:
Polyolefin pipes are welded end-to-end by a self-propelled, self-contained machine which performs all steps necessary to the process without need for any other machines or equipment. Hydraulically driven parallel tracks are independently controlled for maximum maneuverability. An hydraulically driven, computer controlled, reversible jaw assembly reciprocates the new pipe section relative to the exiting pipe line. A facer for trimming and squaring the pipe ends to be joined and a heater for melting the pipe ends for fusing are umbilically connected to the machine for on-board or remote operation. The computer, also on an umbilical, enables the operator to operate the machine in a normal mode in which the operator manually controls the facing, soaking and fusing processes or an automatic mode in which the fusing process is automatically controlled by the computer. The computer also allows the operator to choose a data logging mode in which the operating pressure, heater temperature and time data are recorded to provide a history for each joint made by the machine.
