Provided is a reducing material for gas pressure welding that enables attachment of a reducing material for gas pressure welding onto a tip portion of a material to be pressure-welded in a state where a gap between tip surfaces of respective materials to be pressure-welded is narrow when the reducing material for gas pressure welding is attached onto the tip portion of the fixed material to be pressure-welded such as a steel material. A reducing material for gas pressure welding D1 includes a thermoplastic resin cap body 1a that can be externally fitted onto a tip portion on a pressure-welded side of a material to be pressure-welded, and the cap body 1a has a body portion 10 provided with a cut edge 120 in a circumferential direction with a predetermined thickness along a top plate 11 of the cap body 1a, having a width allowing the cut edge 120 to be fitted around the material to be pressure-welded, and provided with cut edges 122, 123 continuing from the cut edge 120 to a hem end portion in substantially at a right angle to the top plate 11 at the remaining thickness portion of the body portion 10 to form a fitting opening portion 12.
A reducing material for gas pressure welding comprising a cap body that can be externally fitted onto a tip portion of a material to be pressure-welded, wherein the cap body has a body portion formed with an opening/closing portion or a fitting opening portion that can be fitted around the material to be pressure-welded from a side surface so that a top portion of the cap body comes in contact with a tip surface of the material to be pressure-welded.
A reducing material for gas pressure welding comprising a cap body that can be externally fitted onto a tip portion of a material to be pressure-welded, wherein the cap body has a top portion that comes in contact with a tip surface of the material to be pressure-welded and a required number of body leg portions provided in a circumferential direction of the top portion, and an interval between at least a pair of the body leg portions adjacent to each other is formed to be substantially equal to a diameter of the material to be pressure-welded or larger than the diameter of the material to be pressure-welded.
A reducing material for gas pressure welding comprising a cap body that can be externally fitted onto a tip portion of a material to be pressure-welded, wherein the cap body has a body portion formed so as to be fittable around the material to be pressure-welded from a side surface by deforming a shape of the body portion so that a top portion of the cap body comes in contact with a tip surface of the material to be pressure-welded.
A reducing material for gas pressure welding comprising a cap body that can be externally fitted onto a tip portion of a material to be pressure-welded, wherein the cap body has a body portion provided with a separable weakening line so as to form a fitting opening portion that can be fitted around the material to be pressure-welded from a side surface.
A gas pressure welding method comprising the steps of:
