track potential changes that need to be made to the weld rating algorithm. In cases where
the operator rejects the Spotweld Assistant recommended stamp, or in cases where the
weld nugget has been rated anything other than GOOD, the weld data is highlighted in
RED to alert the operator.

9.9 Interface Gate
The EPOCH 4PLUS employs the Interface Gate principally in immersion applications
where the water path distance between the front surface of the test material and the
transducer face is continuously changing. The application may involve an “on-line” type
approach with the test material moving steadily past a stationary transducer (or vice
versa). If the front surface of the test material is not uniform, a slight difference in the
water path distance may result.
The Interface Gate option graphically compensates for the change in water path distance
between the test material and transducer. When the option is activated, a third gate
(Interface Gate) is visible on the EPOCH 4PLUS display. You can position this Interface
Gate in the area where you expect to detect the interface echo. The interface echo is a result
of the sound energy reflection at the interface between the water path and the front surface
of the test material.
The advantage of using the Interface Gate is that it maintains the interface echo on the left
side of the EPOCH 4PLUS screen, regardless of the water path distance. The instrument’s
flaw gates (Gates 1 and 2) automatically track the location of the Interface Gate.
