Dr. Livingstone, I Presume WELDWISE 2400 - Manual (Page 128)

PROBLEM POSSIBLE CAUSE OR
SYMPTOM
POSSIBLE FIX
Tolerances are improperly adjusted. Analyze the weld data and process to determine which
parameters need tighter tolerances to REJECT defective welds.
Displacement sensor was not zeroed before
a new Master was created. Displacement
readings are inaccurate or static. Check the zero reference of displacement sensor and zero if
necessary. Create a new Master or set of Master Tolerance
Limits and examine the weld data for inconsistencies.
A sensor was not calibrated correctly
before a new Master was created, or was
recalibrated after the master was created. Using the Input Monitor, check the calibration of the sensors
and recalibrate if necessary. Create a new Master or set of
Master tolerance limits and examine the weld data for
inconsistencies.
WELDS THAT SHOULD
BE REJECTED ARE
NOT BEING
REJECTED: The weld
summary screen indicates
that welds have an ACCEPT
status of "0" for parts that
should be REJECTED.
A sensor is malfunctioning and a new
Master was created. Sensor readings are
inaccurate or static. Using the Input Monitor, check the calibration of the sensors
and recalibrate if necessary. Create a new Master or set of
Master tolerance limits and examine the weld data for
inconsistencies.
