The present invention relates to a rotary roller device for a pipe welding work and, more specifically, relates to the rotary roller device to improve operational efficiency through a more efficient non-powered rotation of a pipe for a welding work. In the rotary roller device for a pipe welding work deposited on an upper part of a roller supporting frame (10) where a plurality of rotary rollers (11) provided in a pair for a pipe (30) to be welded may rotatably be seated; the present invention, to achieve the above purpose, comprises a braking measure arranged to control the rotation of a rotary roller (11) on a side of the roller supporting frame (10). The braking measure comprises: a body rod (20) configured to be moved centering on a hinge shaft (21) fixated to the roller supporting frame (10); a brake pad (22) deposited on one side of the body rod (20) corresponding to the rotary roller (11); and a weight slidingly moving to an other side of the body rod (23). |
