摘要:
There is provided a welding system and a welding method of cylindrical structures capable of efficiently welding the cylindrical structures with high precision. A welding system of cylindrical structures which welds a welding end surface of an upper cylindrical structure and a welding end surface of a lower cylindrical structure, each of which being an end surface in an axial direction thereof and facing each other, includes: two or more welding apparatuses which are opposite to the welding end surfaces of the upper cylindrical structure and the lower cylindrical structure and are disposed at equal arrangement intervals in the circumferential direction of the cylindrical structures; a moving device which is configured to rotate the upper cylindrical structure and the lower cylindrical structure relative to the welding apparatuses in a circumferential direction of the cylindrical structures; and a control device which is configured to control operations of the welding apparatuses and the moving device, wherein each of the welding apparatuses has a filler metal and a heating source which melts the filler metal, and is configured to melt and fuse the filler metal on the welding end surfaces to thereby weld the welding end surfaces, and the control device is further configured to continuously rotate the upper cylindrical structure and the lower cylindrical structure by an angle of the arrangement interval of the welding apparatuses by the moving device, while welding the welding end surfaces with the welding apparatuses.
