Ultrasound Device for Improvement Treatment of Parts and Welded Joints; said device comprises a housing with a handle and sliding guides, wherein a sleeve with an attachment possessing the ability of reciprocal motion is affixed; said sleeve contains, over vibro-insulation packing, an ultrasound transducer installed on the nodal plane and connected to the oscillation velocity transformer; a temperature sensor and a sensor of the sleeve position in relation to the housing; a forced air-cooling system for the transducer based on feeding compressed air at the butt end of the sleeve and discharging it in the area of the exit opening of the velocity transformer, said transformer being in contact with the striker tips capable of the reciprocal motion and positioned within a working head; the cylindrical end of said working head is mounted on the attachment with the ability of rotation and quick removal; the movement of the sleeve is limited by means of a pin anchored on the sleeve and positioned in a longitudinal slot on the housing and affixed to the front edge of the slot by a spring located between the shoulder formed on the sleeve and the butt-end surface of the housing, with the ability of the sleeve to shift when the strikers are pressed; a shifting spigot equipped with pins inserted into shaped slots made in the housing with the ability of anchoring the axial movement of the spigot in three positions, is installed between the spring and the butt-end surface of the housing; said working head with strikers is anchored, to avert axial movement, by means of a spring ball lock, the ball of which enters either one of the sockets made with a one-plane angular pitch or a circular groove made on the cylindrical end of the working head; said handle is attached to the housing through an extender and shifted in the direction opposite to the working head.
