Pressurizing assembly, device and method for diffusion welding of curved-surface workpiece

Abstract

A pressurizing assembly includes: a dot-matrix pressurizing member including a driving base and a plurality of pressurizing rods, the driving base being provided with a plurality of mounting positions arranged in a dot-matrix pattern, with each pressurizing rod mounted at its respective mounting position and all the pressurizing rods being parallel to each other, and the driving base being configured to independently drive the plurality of pressurizing rods so as to apply localized and independent pressure to the curved-surface workpiece; and an induction heating element disposed adjacent to a free end of each pressurizing rod to heat respective surface regions of the curved-surface workpiece.
