The utility model discloses a pipeline with a welding positioning structure. The connecting pipe comprises an outer pipe body and an inner pipe body, the outer wall of the inner pipe body extends outwards to form an annular flange, one end of the outer pipe body is provided with a pipe opening welded to the annular flange in a matched mode, the pipe opening abuts against the annular flange, and the pipe opening and the annular flange are welded in a matched mode so that the inner pipe body can be fixed to the outer pipe body in a sleeving mode. By means of the mode, the annular flange on the inner pipe is matched with the pipe opening in the outer pipe for welding, the inner pipe is positioned on the outer pipe in an outer positioning mode, damage to the outer pipe is effectively prevented, unnecessary procedures are reduced, and therefore the working efficiency is improved. 本实用新型公开了一种具有焊接定位结构的管道，包括外管和内管，所述内管的外壁上向外延伸有环形凸缘，所述外管的一端上设有与所述环形凸缘相配合焊接的管口，且所述管口与所述环形凸缘相抵靠，所述管口和环形凸缘相配合焊接以将所述内管套接固定在所述外管上。通过这样的方式，内管上的环形凸
