It is a metallurgical processing method by which ultrasonic vitality is utilized to a metallic object. Ultrasonic treatment may end up in controlled residual compressive stress, grain refinement and grain measurement discount. Low and excessive cycle fatigue are enhanced and have been documented to provide increases as much as ten times greater than non-UIT specimens. Additionally, UIT has proven efficient in addressing stress corrosion cracking, corrosion fatigue and related points. By 2005, ultrasound technology began to be used by the beef cattle business to improve animal health and the yield of cattle operations.

Filters and detectors discriminated between the various operations. The principal advantages had been that no battery was wanted in the hand-held control field and, not like radio waves, the ultrasound was unlikely to affect neighboring sets. Ultrasound remained in use until displaced by infrared systems starting in the late 1980s.
