Ultrasonic Impact Treatment (UIT) method is an efficient method that can turned the harmful residual stress on the surface layer or weld area into compressive stress. The UIT equipment uses high-power energy to drive impact head to impact metal surface at 20000 times in frequency.

The UIT/UP produces a number of beneficial effects in metals and alloys. Foremost among these is increasing the resistance of materials to surface-related failures, such as fatigue and stress corrosion cracking. The fatigue testing of large-scale parts and welded specimens showed that the UIT/UP is the most efficient improvement treatment as compared with traditional techniques such as heat treatment, TIG-dressing, hammer peening and shot peening. 

Ultrasonic impact treatment technology is a cost effective method for increasing the safety and endurance of structures, so UIT has being accepted in many industries as a superior and viable technology for fatigue enhancement.
