Background

Both the elbow and the flange are indispensable important pipeline components for pipeline engineering. Both the water supply and drainage pipeline and the fuel gas conveying pipeline can be used. In the laying process, the two assemblies need to be matched for use so as to complement each other to achieve a better effect.

When the flat welding flange and the elbow are connected, the flange is connected into a section of straight pipe firstly and then welded with the elbow, and a workpiece shown in figure 1 is formed by welding the straight pipe, the flange and the elbow, wherein the flange can be directly placed on a table-board when the straight pipe and the flange are welded, and then one end of the straight pipe is vertically inserted into the flange for welding; however, when welding the elbow and two straight pipes, it is necessary to horizontally hold up one set of welded straight pipes and flanges, and to ensure that the axis of the held straight pipe is perpendicular to the axis of the vertically placed straight pipe. Currently, when the welding step is performed, two workers are required to operate simultaneously, one person assists in holding the workpiece, and the other person is responsible for welding. This approach wastes labor and does not guarantee the accuracy of the welding location.
