What is 'cold welding' in the context of Passivity Plus?
Cold welding refers to the mechanical joining of two precisely matched conical titanium surfaces (5° per side) pressed together under proper torque, creating an extremely tight, friction-locked connection.
This metal-to-metal engagement distributes load throughout the structure and prevents micromovement that leads to screw loosening.
It is NOT a permanent metallurgical bond — the screw releases normally when unscrewed, allowing the self-adjusting mechanism to reset and be engaged again.
