Reconditioning Stack
Components
To restore the interface to the proper condition, do the
following:
1. Disassemble the transducer/booster/horn stack and
wipe interfaces with a clean cloth or paper towel.
2. Examine all interfaces. If any interface is corroded or
shows a dark, hard deposit, it should be reconditioned.
3. If the interfaces appear to be in good condition, go to
Step 11.
4. If necessary, remove the mounting studs.
5. Tape a clean sheet of #400 grit (or finer) silicon carbide
wet-or-dry paper to a clean, smooth, flat surface. A
piece of plate glass is usually suitable.
6. Hold the part to be conditioned at its lower end with
your thumb over a spanner wrench hole. Carefully
stroke the part once in one direction (toward you)
across the abrasive paper, as shown in Figure 8- 4.
Do not apply downward pressure. The component's
weight alone provides sufficient pressure. Perform a
second stroke.
7. Rotate the part 120° (1/3 rotation) to the next
spanner wrench hole. Repeat the procedure outlined
in Step 6.
8. Rotate the part the remaining 120° and repeat. Be
certain to perform the same number of strokes at each
orientation: Two strokes per rotation.
9. Before reinserting a stud in any horn, perform the
following for proper engagement of the threads:
a. Visually inspect and clean the stud.
b. Clean the threaded hole using a clean cloth or
towel.
c. Tighten the stud to the torque specifications listed
in Table 7-I.

NOTE
The operating efficiency of the
equipment will be greatly affected
if the mating interfaces of the trans-
ducer/booster/horn stack are not flat,
make poor contact with each other,
or become corroded. A poor con-
tact condition wastes power output,
makes tuning difficult, can affect the
noise level, and can cause possible
heat damage to the transducer.
CAUTION

avoid tilting the part. Loss

inoperative.
Figure 8-4 Method of Component Resurfacing
Use extreme care to
avoid multiple strokes at
each 1/3 rotation of the
part. Loss of flatness
and perpendicularity of
the interface surface to
the centering axis of the
part may render the welding system
inoperative.
