摘要：The present invention provides a pipe joining structure and a joining methodcapable of ensuring sufficient joining strength while suppressing cost as much as possibleand capable of being easily joined. A pipe joint structure in which a second pipe 53 isjoined to a first pipe 51, a cylindrical joint 55 is formed on a peripheral surface of the first

pipe 51, and a second pipe is formed on an end surface of the joint 55. The end face 63 isabutted and joined by welding, and the joint 55 is made of a layered product in which aweld bead obtained by melting and solidifying a filler material is laminated on theperipheral surface of the first pipe 51.
