Solution introduction
The electromagnetic guided wave detection solution for the tension springs connected to the train carriages adopts electromagnetic guided wave technology, which can meet the requirements of customers for the quality inspection of the tension springs.
Main characteristic
Electromagnetic ultrasonic guided waves use electromagnetic fields as a medium to send and receive ultrasonic waves, so no coupling agent is needed;
Since no coupling agent is needed, there is no coupling change problem, and the detection sensitivity is stable;
The surface of the tested workpiece does not affect the electromagnetic ultrasonic testing;
The guided wave has a long propagation distance, small attenuation coefficient, and high detection efficiency.
The figure1 is half through-hole; figure 2 is longitudinal notch; figure 3 is the testing piece; figure 4 is defect on the testing block, left is longitudinal notch, the right is half through-hole;
