ABSTRACT:
Track to provide travel of a welding carriage about a pipe, including a metal band bent to encircle a pipe and being supported by slotted crossbars, the slots of the crossbars providing resiliency to the band so that the band will yield when tightened about the pipe, and so that the pipe may expand and contract under changes in temperature without longitudinal overstressing of the band and the latch connecting the ends of the band. The invention includes locator apparatus for spacing the track from the end of a pipe, including one or more adjustable locking pliers fitted to provide pipe end and track engagements and suitable to serve as a guide for locating the position of the track with respect to the pipe end.
