half of the Up-slope level and the Final Slope level. This is called the
Welding Sequence.
As the weld progresses through the weld levels, the screen shows the
parameter values for the current welding level, including; time left and/or
degrees left in the level, degrees left in the full rotation of the tungsten
around the part, the pulsing current, the resultant pulsing voltage, and
the motor speed value all of which show on their respective bar graphs.
Once the welding sequence is complete, the program will finish in the Final
Slope level.
This level will tail out and taper the weld so that there is no cratering
effect left at the end of the weld, once the arc is extinguished.
Typically, when designing a procedure using APG, the Final Slope
current will slope down while the motor will slope up.
The gas Post-Purge will start immediately after the arc is extinguished at
the end of the Final Slope. It will stay on for as long as programmed.
At the end of the Post-Purge time, the rotor will then rotate in the normal
direction until it reaches home position. This will only occur if the Post-
Weld Home option is enabled for the procedure. When designing a
procedure from APG, this option is enabled by default.
To keep extra gas flowing, the ACL program is designed to keep gas
flowing until the rotor reaches home position. If the Post-Weld Home
option is not enabled, then the gas will stop flowing at the end of the
time period.
2.5 Deviation Screen, Report & Log
Once the weld finishes, the rotor returns to home position and the gas has
stopped flowing, the weld log will appear on the screen; and if enabled it will
also print and/or save to diskette.
This weld log contains all needed information concerning the status of the
completed weld. When used in conjunction with the Data Monitoring option
(see MODIFYING WELD PROCEDURES) this log will produce a report on
the screen showing all the deviations that occurred during the entire Weld,
or Test operation.
A weld log will appear on the screen after each and every weld. A printout
of the weld log, a Deviation Report will generate only if either the Print All
Logs or Print On Error options are enabled.
The weld log consists of several items of pertinent information:
Procedure Name and Description; Name & Two Headings; Applied
Current and/or Motor Scaling; Weld Serial Number; Total Number and
Type of Deviations Detected; Procedure and Abort Limit Values (if
programmed).
The number of deviations may be large or small, depending on the type
of deviation detected. Both the screen and the printout will show the first
fifteen deviations, and the absolute last one.
If an Abort Limit caused the last deviation, the top of the deviation report
would show that the weld was aborted. The last deviation, if it greater
than the sixteenth, would show exactly what type of deviation occurred
to abort the weld.
Each procedure can be modified to not only print, but also save the weld
log at the completion of the weld.
In order to save each and every weld log, or just the weld log of those that
had deviations, at the options screen for the procedure enable either of the
two Save Log functions.
