text: UIT is highly controllable. Incorporating a programmable logic controller (PLC) or a Digital Ultrasonic Generator, the frequency and amplitude of UIT are easily set and maintained, thus removing a significant portion of operator dependency. UIT can also be mechanically controlled, thus providing repeatability of results from one application to the next. Examples of mechanical control employed with UIT include:
  *CNC milling machines
  *Lathes
  *Robotic control
  *Weld tractors
  With these types of controlled applications, the surface finish of the work piece is highly controllable.
  For many applications, UIT is most effectively employed by hand. The high portability of the UIT system enables travel to austere locations and hard to reach places. The flexibility that is facilitated by variations in the tool configuration (such as angle-peening-head) ensures that access to very tight locations is possible.
  UIT's effectiveness has been illustrated on the following metals, among others:
  *Aluminium (including sensitized Aluminium)
  *Bronze
  *Cobalt alloys
  *Nickel alloys
  *Steels
  **Carbon steel
  **Stainless steel
  **High-strength low-alloy steel
  **Manganese steel
  *Titanium
