inertia friction welding machine

Inertia friction welding machine is a highly efficient and consistently reliable metal joining process. By generating heat near the melting point through friction between two metal materials, the rotating friction welder applies forging pressure during the plastic deformation stage. This causes molecular diffusion and interpenetration of the materials. Upon cooling and recrystallization, a solid-state welded joint is formed free of oxides, porosity, or contamination.

Rotary friction welding achieves solid-state bonding while metals remain in a thermoplastic state. The welded joint exhibits physical and mechanical properties nearly identical to the base materials, offering high welding efficiency, consistent quality, and product uniformity. It also enables the joining of dissimilar metals.

Due to its advantages of high efficiency, energy savings, and economic benefits, the rotary friction welding machine is widely applied in industries such as aerospace, nuclear energy, marine development, new energy, power generation, machinery manufacturing, oil drilling, and automotive manufacturing.
