Non-Destructive Inspection ATLAS

Example of FSM - Monitoring

mark Bridge and elevated expressway

The advantages of using FSM testing for bridge inspection are that traffic control is no longer necessary and works at a high altitude can be minimized.   It is applicable to overall ferrous materials (slabs, girders and piers), weld, fillet welding points and buried structures.   In the FSM testing for trestles of a bridge, for example, cracks on welding points can be monitored and detected through measuring electric potential differences between sensing pins placed directly on a key weld line and passing an electric current through the sensing pins.
