Calculate friction welding rotational speed, axial pressure, upset distance, and energy for rotary and linear friction welding
Input Parameters

--
Rotational Speed
RPM

Surface Velocity
m/s

Axial Force (Friction)
kN
--
Expected Upset
mm
Note: Friction welding is a solid-state process. No melting occurs - heat is generated by friction at the interface. Forge pressure applied after friction phase completes the bond.
Reference
Rotary Friction Welding:
Surface velocity: 1.5-4.0 m/s (material dependent)
RPM = V_surface * 60 / (2*pi*R_mean)
Axial force = pressure x cross-section area
Upset distance increases with friction time and temperature
