For any critical application, we believe that we should use the most accurate available method for measuring residual load on the bolts.

This method is the measurement of the elongation of the bolts by using our ultrasonic system, obtaining the exact load in the bolt.

This allows not only being very accurate on the residual load, but controlling possible dispersions (scattering) that adversely affect the life of the joint.

Our supervisors have the qualification required for the use of this equipment.
