METHOD FOR ULTRASONIC IMPACT TREATMENT OF SURFACES OF COMPONENTS AND WELDED JOINTS

摘要

The invention relates to ultrasonic impact treatment of components arranged underwater. An ultrasonic vibratory instrument is submerged in water. Movable impact elements of the ultrasonic vibratory instrument are pressed against a surface being treated and said instrument is moved relative to the surface being treated. The impact elements are in contact with an outlet end of an ultrasonic oscillating-speed transformer. Ultrasonic vibrations of the outlet end of the ultrasonic oscillating-speed transformer are excited at an intensity exceeding the threshold at which extensive cavitation arises on said surface and in the area in which the movable impact elements are arranged.
