Abstract: PURPOSE: A butt-welding structure of a synthetic resin pipe by using a fusing ring is provided to prevent damage of the fusing ring by installing a heater separately from the ring and to improve pipe-laying and fusing-work efficiency of the synthetic resin pipe without cutting the broken fusing ring or the resin pipe attached with the ring. CONSTITUTION: In a butt-welding structure for welding a synthetic resin pipe attached with a fusing ring(20) to each other, the fusing ring has an inside melted to one synthetic resin pipe and a fusion surface(22) contacting to the fusing ring of the other synthetic resin pipe. A heater settling unit(23) contacted with a heater is disposed on the fusion surface. A combining projection(25) having a bolt hole(24) for joining physically the fusing rings confronting with each other by a bolt and a nut is formed at the outer periphery of the fusing ring.
