Sonic Unit Capabilities

All material is 100% Ultrasonically tested as per DOT-3AL, PARA 178.46-5e
Two probes are used. One probe makes contact with the billet on the bottom and the other makes contact at the side, 90 degrees from the first probe.
Each probe has its own sonic unit with a readout screen.
The X scale on the readout represents distance starting at the entry surface, represented by 0. The back reflection occurs at the distance equal to the thickness of the billet.
The Y scale represents the amplitude of the defect detected.
The reject zone is set up to stop the unit anytime a reject is detected with an amplitude exceeding a 5/64" diameter axial hole and at a location that is approximately within the center 60% of the scanning distance.
