Abstract
Problems of ultrasonic elastic vibration influence on materials are discussed. Treatment of a welded item by ultrasonic vibrations in a wide frequency band is proposed. Possibility of formation of a more fine-grained structure as a result of such treatment both in the weld metal and HAZ in arc welding of ordinary carbon steel St3sp is shown
Keywords: arc welding, ultrasonic vibration impact, solidification, weld, HAZ, residual stresses, metal structure
