1. A method of coupling pipes, comprising:

  • connecting a first re-rounder to a first pipe;

    connecting at least one linear actuator to said first re-rounder, said at least one actuator being movable in a first direction which is transverse to said first re-rounder;

    connecting a second end of said at least one linear actuator to a backstop, said backstop being movable with said at least one linear actuator;

    performing a first moving step comprising moving a coupling on to said first pipe with said backstop and said at least one linear actuator;

    connecting a second re-rounder to a second pipe;

    loosening said first re-rounder;

    performing a second moving step comprising moving of said linear actuator to move said first re-rounder to engage said coupling and further move said coupling into engagement with said first and second pipes; and

    , fusion welding said coupling to said first and second pipes.
