Techniques for stabilizing the angle of entry of ultrasound against fluctuations of the ambient temperature and the temperature of the tested material and the contact fluid are discussed, along with the angle-beam transducer configurations for implementation of the proposed techniques. The results of tests of the newly designed transducers are given. The positive results of the experiments permit the given transducer configuration to be incorporated into a newly constructed portable laboratory for flaw detection in drill pipe.
