摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 to the non-destructive control of ultrasound techniques and can be used for the quality control of materials of various products, covered with s and welded connections.the purpose of u0438u0437u043eu0431u0440u0435u0442u0435u043du0438u00a0 -- improving the sensitivity u043au043eu043du0442u0440u043eu043bu00a0 thin-walled articles and coatings - u0434u043eu0441u0442u0438u0433u0430u0435u0442u0441u00a0 due to the fact that when a reference echo signals ol u0438u043du0438u043cu0430u044eu0442 summary echo signals reflected from the front and rear of the reference model of the same thickness and shape and of the same material, and the controlled u0438u0437u0434u0435u043b s,and u0434u043bu00a0 u043fu043eu0432u044bu0448u0435u043du0438u00a0 productivity u043au043eu043du0442u0440u043eu043bu00a0 thin-walled products and u043fu043eu043au0440u044bu0442u0438u00a0 set minimum amplitude signal by u0438u0437u043cu0435u043du0435u043du0438u00a0 u0437u0430u0434u0435u0440u0436 stock ci t. 1 u0437.u043f.u0444 - lu, 4).
