What is the quality of the welded flange?

    Flange, also known as flange flange or flange. The flange is the part of the shaft and the shaft that is connected to each other for the connection between the ends of the pipe. It is also used for the flange on the inlet and outlet of the device for the connection between two devices, such as the flange of the reducer. Reducer flange for the connection of the motor to the gear unit and the connection between the gear unit and other equipment.

    According to the connection type of flange connection, it can be divided into: plate type flat welding flange, neck flat welding flange, neck butt welding flange, socket welding flange, thread flange, flange cover, neck butt weld ring Loose flange, flat welding ring loose flange, ring groove flange and flange cover, large diameter flat flange, large diameter high neck flange, eight-word blind plate, butt weld ring loose flange.

    Some preparatory measures are required when welding the flange. The required equipment includes a set of manual welding equipment, a handle angle grinder, an electric hammer and a flat ruler. Before the welding, it is necessary to check the debugging equipment to ensure the normal operation of the equipment. Dry the prepared electrode as much as possible at 300 °C-350 °C for one hour. Then you can start welding. First assemble the vertebral body and the large flange according to the requirements of the drawings, and then divide the large flange into 8 equal parts. Due to the thicker flange and larger groove, the welding uses segmental symmetry and multi-layer welding. Finally, the weld strength is required to at least reach the strength of the base metal. The surface of the weld is smooth and smooth, and there are no defects such as burn through, pores, welds, slag inclusions, undercuts, and insufficient welds. The residual height is less than 2mm.

    As a welding flange, many customers question whether the quality of the iron plate welding flange is better than the forged welding flange. In fact, the quality of the iron plate welding flange and the quality of the forged welding flange are the same, but the iron plate welding flange can not be guaranteed in any place, that is, the material of the iron plate welding flange is the most unsafe, because In the general process, the density of the iron plate welding flange is not problematic, but in the process of production, the blank of the iron plate welding flange is rarely detected, so, after production, it does not pass. The material of the tested iron plate welding flange is not guaranteed.
