PROBLEM TO BE SOLVED: To provide a transfer apparatus of a welding head in a piping inner face, the apparatus in which a length of a fixing part can be adjusted in accordance with the size of piping. SOLUTION: The transfer apparatus is characterized in that it is composed of: an interlocking chuck 3 to be a main body; a fixing part 5 for fixing the main body in piping; a rotationally driving motor 13 for generating a motive force for the purpose of welding in the circumferential direction of the piping 1; a rotationally driving part 15 for transmitting the motive force of the rotationally driving motor; a rotary cover 17 that protects the rotationally driving part, that is formed in a manner making the transfer apparatus longitudinally mountable, and that rotates in the circumferential direction of the piping; a forward/backward transfer motor 21 that generates a motive force for welding in the longitudinal direction of the piping; a welding head part 7 which is provided with a welding torch 9 and a camera, and moves in the longitudinal direction of the piping; and a display part 39 for showing the welding state of the welding torch and the internal state of the piping.
