Inspection Mode (Basic)
Once both GOOD and UNWELD reference conditions are stored during setup of the
Spotweld Assistant software, the operator can proceed directly to the inspection of
unknown weld conditions. In the inspection mode, the operator simply interrogates the
unknown weld nuggets and a weld rating is displayed at the top right corner of the screen.
This rating is based on default echo attenuation, echo spacing, and intermediate echo
tolerances, as well as the GOOD and UNWELD reference conditions stored during setup.
To enter the inspection mode from the setup screen, press the [F5] function key (labelled
INSPECT).
In addition to the dynamic weld rating automatically displayed on screen, the EPOCH
4PLUS Spotweld Assistant software allows the operator to store weld condition templates
and overlay these templates with a live signal for comparative purposes. This is the same
functionality as the EPOCH 4PLUS Spotweld Overlay software option, described in
Section 9.7. The operator can recall the GOOD and UNWELD reference conditions from
the setup mode and can also store weld templates for four additional labelled weld
conditions, including U/S (undersized), STICK, THIN and BURNT.
Storing other weld templates is accomplished using the same process as storing the
reference weld conditions:
1. Once a weld condition is captured and characterized, use the FREEZE key to freeze
the A-Scan display. If using the AUTOFREEZE option, this is done automatically.
