Reference Weld Setup
After activating the EPOCH 4PLUS Spotweld Assistant software option, the operator sets
up the reference conditions for a known GOOD and UNWELD pattern. The storage of
these two reference waveforms provides the basic parameters for the dynamic weld rating
algorithm.
Before storing these reference waveforms, it is necessary to adjust the screen range and
gain so that a clear and complete inspection of the ring-down pattern can occur. Usually,
the gain is adjusted so that the first echo from the weld nugget reaches approximately 80%
of full screen height. The range is set so that the ring-down pattern can be observed
through multiple reflections. The screen range for a GOOD weld should show the full
attenuation of the multiple echoes and usually include range beyond the last noticeable
echo.
