Summary: Relevance of the topic. In the process to increased requirements for the quality and competitiveness of products, the role of non-destructive testing methods is increasing. The presence of a large number of factories and factories where welding compounds of low carbon steels are made requires the development of equipment and automation of quality control processes. The quality control of products at an enterprise is an important task, which is why the development of an ultrasonic flaw detector is urgent.
The aim of the study The aim of the work is to analyze existing methods of non-destructive testing of defects in materials, to study the process of propagation of acoustic waves in low-carbon steels. Development of ultrasonic defectoscopy device with improved defect detection characteristics. To achieve this goal, the following tasks need to be addressed:
a) develop the design of an ultrasonic flaw detector with the use of a modern elemental base;
b) to carry out the mathematical modeling of the ultrasonic flaw detector;
c) analyze the results of the simulation and draw conclusions;
d) to design the device of ultrasonic control;
e) submit materials for the report on the student's scientific
e) conference "Information Society: Technological, Economic and Technical Aspects of Formation" (Issue 32);
g) to report on the master dissertation results.
Object of research: Ultrasonic flaw detector.
Subject of research: the process of propagation of acoustic waves in low-carbon constructional steels.
Research methods: Method of ultrasonic defectoscopy.
Scientific novelty of the obtained results. A generalized constructive approach is proposed for registration of defects in welded joints.
The practical value of the results obtained the ability to use the device at the manufacture to control the quality of products from low carbon steel.

Keywords: ultrasonic flaw detector, non-destructive defectoscopy, quality control, low carbon steel,welded joints.
