Various typesExport flangeFeatures: 1. Socket welding flanges are suitable for small diameter, high voltage, and high temperature pipelines.
2. Flat welding has a boss like butt welding, with a groove opened on the boss, and then the pipe is inserted for welding.
3. Socket welding does not have a boss; a groove is directly opened on the flange body, like opening a hole on a blind flange, and then another groove is opened.
4. Flat welding is slightly better than socket welding.
During resistance welding, the two workpieces are always kept under pressure. When the end face temperature rises to the welding temperature Tω, the distance between the end faces of the two workpieces will reduce to a few angstroms, leading to atomic interactions that create common grains at the joint, thus forming the weld. There are two welding cycles in resistance welding: isostatic and forging enhancement. The former has a simple pressure mechanism and is easy to implement. However, employing the electric top forging process can yield better welding quality. To ensure the plastic deformation of the alloy butt welds and further enhance the joint quality, the electric top forging process should be adopted.
InExport flangeWhen butt welding with resistance, the two workpieces should have the same end face shape and size to ensure that the heating deformation of the workpieces is consistent with the plastic deformation. The end faces of the workpieces must be strictly cleaned, as well as the surfaces in contact with the clamps. Oxides and dirt on the ends will directly affect the quality of the seam. The oxide scale and dirt on the surface of the workpiece in contact with the clamps will increase the contact resistance, exacerbate the wear of the workpiece surface jaws, and increase power loss.
