The article gives short knowledge on ultrasound tomography and presents results of experimental investigations on stainless steel welding seam flaw detection. Such seams are widely used in chemical and petrochemical industries, in power engineering and others. The investigations were performed with a tomograph “Omniscan” and ultrasound phased arrays manufactured by the company “Olympus NDT” (Japan – Canada). Advantages of this equipment over usual ultrasound instruments are shown by practical examples.
