摘要

method of control of welding joints of tubular parts which are housed in the log gets rid of a number of blocks (7a, 7b, 8a.8b) u044du043bu0435u043au0442u0440u043eu043cu0430u0433u043du0438u0442u043du043e - acoustic transducers (u044du043cu0430u043f) circumference in the vicinity of the internal and / or external surface of the at least one the log gets rid of u0434u0435u0442u0430u043b welded tubeshe and his u044du043cu0430u043f - units for transferring sequentially or simultaneously u0441u0434u0432u0438u0433u043eu0432u043eu0439 acoustic waves in the direction of welded connections, to disclose to u0434u0432u0438u0433u043eu0432u044bu0435 wavesas the u0441u0432u0430u0440u043du044bu043c connection and / or the past through it, with the u044du043cu0430u043f - blocks being held in fixed position on the u0441u0432u0430u0440u043d wow compounds, resulting inat least a part of the welded connection of the scanning u044du043cu0430u043f - blocks immediately after its creation.the application was published, together with the report on the international market.
