It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection in which flange, gasket and bolts are connected to each other as a combined sealing structure.

[0003] The patent with patent announcement number CN212793626U discloses a flange welding device, which relates to the field of flange technology, in order to solve the problem that the existing flange welding device has low welding flexibility and cannot be properly adjusted according to actual needs. A side fixing vertical plate is installed on one side above the welding workbench, an auxiliary support stabilizing bar is installed on the other side of the side fixing vertical plate, an upper fixing block is installed on the upper end of the side fixing vertical plate, a rotating motor is installed above the upper fixing block, a transmission screw is installed inside the side fixing vertical plate, a screw moving sleeve is installed at the front end of the side fixing vertical plate, an electric telescopic rod is installed at the front end of the transmission screw, an electric rotating shaft is installed at one end of the electric telescopic rod, a welding fixing head is installed below the electric rotating shaft, and a flange placement mechanism is installed on the other side above the welding workbench.
