Apparatus is described for transporting sections of pipe and connecting them together for laying pipe above ground or in a trench. The apparatus includes a wheeled frame (e.g., a trailer), a support for one end of a first pipe section, and an alignment mechanism for supporting the other end of the first pipe section and the leading end of a second pipe section so that the opposing ends of the pipe section can be welded together.
