Rotational Friction Welding
A solid-state joining process where the bond is created through frictional heat generated by relative rotational motion of the components followed by upsetting.
In friction welding, the parts are rubbed together under pressure until the friction heat makes the material plastic at the joint. Then the pressure is increased and rotation is stopped, causing the parts to weld together.
Make sure the faces are clean and flat, otherwise the joint won't hold. If you use too little pressure or too high a speed, the material will burn or the joint won't be sound. Too much heat will cause porosity in the structure.
Keep the parts clean and centered, then you'll get a clean, tight weld.
