Joint mapping

Joint mapping records relationships between welds and joints, as well as recording bends and loose ends. Joint mapping has two purposes:

  • It enables you to create reports in the office showing welding progress, including the location of bends and loose ends.
  • It streamlines data entry when you measure points along the as-built pipeline so that by entering just the weld ID, the details for the linked joints are available for review and editing and are stored with the point.

Joint mapping is completed on a controller such as a TSC7 or tablet and there is no need to be connected to any survey equipment to do this. The position and station can also be recorded. You can use the controller's integrated GNSS to do this, or you can connect to an external GNSS receiver. If you have a GNSS position from a connected Trimble GNSS receiver than this position is always used in preference to the coarse position from the controller's GNSS.

Typically, joint mapping is done after the pipeline has been welded but before it is lowered into the trench. You can map different types of joints, as required.
