Fission welding
Webdivide the welding processes into two major groups: (1) fusion welding and (2) solid-state welding. 1-Fusion Welding Fusion-welding processes use heat to melt the base metals. In many fusion welding operations, a filler metal is added to the molten pool to facilitate the process and provide bulk and strength to the WebApr 29, 2024 · Fusion welding is a method that makes use of heat to combine or fuse two or more materials into a melting point by heating them. The method may involve the use of filler material, or it may not.
