Flat welding flange is the initial stage of forging deformation, because the porous preform is easy to deform, the deformation force is small, and the density increases rapidly. In the later stage of forging, because most of the pores are closed, the deformation resistance increases, and the deformation force required to eliminate the residual pores increases rapidly. Deformation resistance is closely related to deformation temperature. Higher deformation temperature is beneficial to densification and reduces deformation resistance.
Flat welding flange is a forging process which requires more equipment than traditional die forging. The displacement characteristics of punch must match the deformation and compactness characteristics of preform. The contact time between blank and die should be as short as possible.

Flat welding flange not only saves space and weight, but also ensures that the joint will not leak and has good sealing performance. The reason why the compact flange size is reduced is that the diameter of the seal is reduced, which will reduce the cross section of the sealing surface. Therefore, flat welding flange is a kind of high quality flange products, which reduces the quality and space, and plays an important role in industrial use.
