Abstract

New modification of portable ultrasonic equipment with power output of 0,8 kW with the digital management is developed for strengthening and relaxation treatment of surface of metallic hardware. A set of such devices is produced; the designer documentations on an ultrasonic generator and impact instrument with a piezoceramic transducer are prepared. Preparation of technology of ultrasonic impact treatment for welded constructions is accomplished. Conducted comparative tests on the effects of different types of treatment and applied materials of welded constructions on fatigue durability showed the expediency of ultrasonic impact treatment for the prolongation of operation life of wares.
