Afterburst
The next submenu in Process Setup deals with Afterburst.
In some applications the part being welded may stick to
the horn as the head of the press retracts. Afterburst dis-
lodges the part by sending a short burst of ultrasound on
the upstroke.
Afterburst is defined by three values: the delay time, the
duration of the afterburst, and by the amplitude.
Delay
is the time from the start of the upstroke until the
start of the afterburst.
Duration
is how long the afterburst ultrasound signal is on.
Amplitude
defines the amplitude of the afterburst ultra-
sound signal.
The afterburst feature can be turned off by choosing
Dis-
abled
, or it can be turned on by choosing
Enabled
.
When enabled, the delay and duration times and the ampli-
tude are then entered. See the figure to the right.
Weld Amplitude
Weld Amplitude is the next parameter to select. This refers
to the peak-to-peak excursion of the horn at its workface.
Amplitude settings are given as a percent of the horn’s
nominal amplitude in the range of 20% - 100%.
