A tool for use in preparing two members to be welded to one another has a body provided with legs adapted to straddle a gap between the two members and a bridge joining corresponding ends of the legs. The bridge has an elongate slot therein through which extends a drawbar that terminates at one end in a hook which is capable of underlying and engaging the lower surface of only one of such members. The drawbar is adjustable to cause the hook to move toward the bridge and thereby effect relative adjustment of the confronting edges of the two members. The drawbar preferably carries a gauge which may be used to ascertain the relative positions of the lower surfaces of the two members.
