摘要 |
A tightening method and system for practicing same are disclosed herein for tightening a fastener to a desired axial load. According to the method, torque is applied to the fastener until it is tightened to its yield point and either the torque applied at the yield point or the angular rotation of the fastener at the yield point are determined and are used to determine the axial load acting on the joint assembly and these determined characteristics are used to determine either the torque or angular rotation required to tighten the fastener to the desired load. Thereafter, torque is again applied to the fastener and when the actual torque being applied or actual angular rotation of the fastener substantially equals that required to tighten the fastener to the desired load, the application of torque is discontinued. |
