Zusammenfassung:	PURPOSE:To provide a titled jig which enables the considerable improvement in working efficiency for tentative assembling by the constitution wherein work to be welded are enclosed and grapsed in a weldable state with a pair of jig bodies provided with openings for tack welding. CONSTITUTION:A tentative fastening jig body 10 consists of a pair of jig bodies 10a and 10b which are assembled with pipes 14a and 14b and an elbow 16 in a weldable state and are formed with projecting parts 18 so as to enable the enclosing of work to be welded. Openings 12a and 12b for tack welding are provided in said parts 18. The bodies 10a and 10b are connected by means of a hinge 20 to constitute the body 10 freely openably. Means for fastening the body 10 are constituted by screwing bolts 22a and 22b detained with pins 25a and 25b to the bracket of the body 10b by means of nuts 24a and 24b in notches 26a and 26b. A series of operation such as assembling, tentative fastening, tack welding and regular welding of the work to be welded are accomplished efficiently by using the above-mentioned tentative fastening jig for tack welding.
