ABSTRACT:
A method and apparatus for axially aligning the ends of pipes such as pile casings and the like and for supporting these ends in axially aligned relation while they are welded or otherwise secured together. The apparatus includes an alignment jig which can be releasably clamped around one end of a first pipe and includes a plurality of outwardly flared guides which are supported to extend beyond the end of the first pipe. The outwardly flared ends are intended to receive an end of a second pipe as that pipe is moved axially toward the first pipe and to guide that end into axial alignment with the end of the first pipe. The alignment jig is to be clamped to the end of the first pipe in such a manner as to permit free access to the seam formed between the two pipes to permit them to be welded together.
