Abstract

PURPOSE:To obtain the insert ring of required composition by rolling the steel wire to flatness in section shape, coiling it to the winding jig so that its short side surface is parallel to the coiling axial line, pulling out the jig and cutting a part of the steel wire of coil state in the axial line direction. CONSTITUTION:The steel wire 8A for insert ring is rolled to flatness of its sectional shape, next, this rolled steel wire 8B is wound to winding jig 10 of a round rod like in coil like so that its short side surface is parallel to the winding axial line l. Next, the winding jig is pulled out from the above steel wire of coil like, one part of the above steel wire of coil like is cut in the direction of its axial line, then plural pieces of the insert ring are obtained from the steel wire of coil like. Therefore, because the steel wire of the weld wire, etc., can be used, so the insert ring of required composition for welding can be manufactured with the prescribed accuracy and the good yield.
