Residual Torque Check with

Digital Wrench – Torque&Angle DWTA

The goal of quality control is to check how the residual torque in the joint compares with the torque applied during the tightening process 50 Nm 50 Nm

10%+-

Models – Delta 7DFor quality Audit

torque 50 Nm clamping

force 26 kN

residual torque 45 Nm residual clamping force 23,4 kN

In a perfect situation we would like to have the same torque value achieved during the tightening process.

In practice this is difficult as we have several combined influences:

the torque is less due to relaxation of the joint

Models – Delta 7DFor quality Audit

In some cases, we measure more torque due to the static coefficient of friction. This static friction torque does not indicate that there is a higher clamping force, but simply that the coefficient of friction is higher in a static condition and decreases once the parts start moving (dynamic)!

very high static friction coefficient

Residual Strategies

• The operator see the bolt start moving

it’s the breakaway point

• But there is some delay to stop moving the arm, due to body human being decision process

• Residual check value read on the display is different than breakaway point

Peak Torque Strategy :

operator dependant

Models – Delta 7DFor quality Audit

Torque to Move Strategy (using DWTA)

• using the angle, Delta detect the Torque at a pre-defined achieved angle.

• the value detected after a rotation (2° in standard joints) is close to the real breakaway since the peak torque due to static friction is not measured like in peak mode.
