The invention discloses a fixing device used for welding of circular tubes. The fixing device includes a base and a sliding groove, the sliding groove is formed in the center of the upper surface of the base in the horizontal direction, a fixing plate is fixedly installed at one end of the interior of the sliding groove in the vertical direction, and a sliding board is slidingly installed on the side, away from the fixing plate, of the interior of the sliding groove. Through arrangement of an extrusion ring and a retractable rod, a fixing clamp can be used for clamping the circular tubes different in diameter, and by pulling the sliding board, the circular tubes different in length can also be fixed. An arranged motor can drive the fixing clamp to rotate, and correspondingly the circular tubes are rotated to a vertical surface to which the circular tubes need to be welded. Through arrangement of supporting pieces and second springs, a support effect is achieved on the inner walls of the circular tubes, and th
