ULTRASONIC DEVICE FOR REMAINING RESIDUAL STRESSES IN WELDED METAL CONNECTIONS IN THE PROCESS OF AUTOMATIC WELDING

摘要

An ultrasonic device for relieving residual stresses in welded joints of austenitic metals in the process of automatic welding, including an ultrasonic transducer that acts on the metal in the near-weld zone during automatic welding, characterized in that to increase the efficiency of ultrasound, this device is additionally equipped with photodetectors that fix the zone welding, an electronic control unit, devices for moving and pressing ultrasonic magnetostrictive transducers to the surface to be welded, containing a computer in which control commands are generated.
