(54) СПОСОБ ОБНАРУЖЕНИЯ ДЕФЕКТОВ СВАРНЫХ И КЛЕЕВЫХ СОЕДИНЕНИЙ МАТЕРИАЛОВ(54) METHOD FOR DETECTING DEFECTS OF WELDED AND GLUE COMPOUNDS OF MATERIALS
1one
Изобретение относитс к средствам испытани соединений материалов на прочность физическими методами и может быть использовано дл испытани сварных и клеевых швов соедин ющих металлы с различными электропроводност миоThe invention relates to the testing of compounds of materials for strength by physical methods and can be used to test the welded and adhesive joints connecting metals with various electrical conductivities.
Известен способ обнаружени дефектов сварных и клеевых соединений материалов,заключающийс в том, что электромагнитный индуктор располагают в зоне испытани соединени и возбуждают индуктор импульсным током. При этом создаетс импульсное магнитное поле, которое взаимодействует с вихревыми токами в соединенных материалах . В процессе взаимодействи между этими материалами возникает механическое усилие,-направленное на разрыв соединени . По величине импульсного магнитного пол руд т о значении механического усили и о прочности соединени (шва) { .There is a known method for detecting defects in welded and adhesive joints of materials, in that the electromagnetic inductor is placed in the test zone of the joint and excites the inductor with a pulse current. This creates a pulsed magnetic field that interacts with eddy currents in connected materials. In the process of interaction between these materials, a mechanical force arises, directed at breaking the joint. According to the magnitude of the pulsed magnetic field, the value of the mechanical force and the strength of the joint (weld) {.
Однако диапазон 41спытуемых многослойных конструкций не всегда достаточен , в особенности, если по услови м испытани доступ к соединению со стороны материала с низкой электропроводностью закрыт. Тогда материал с высокой электропроводностью экранирует испытуемое соединение.However, the range of tested multilayer structures is not always sufficient, especially if, under test conditions, access to the connection from the side of a material with low conductivity is closed. Then a material with high electrical conductivity shields the test compound.
Цель изобретени - расширение диапазона испытуемых многослойных The purpose of the invention is to expand the range of test multilayer
10 конструкций.10 designs.
Эта цель достигаетс тем, что длительность переднего фронта импульсного toKa устанавливают в несколько раз большей,.чем длительность This goal is achieved by the fact that the duration of the leading edge of the pulsed toKa is set several times longer than the duration
15 его заднего фронта.15 of its back front.
На чертеже приведена схема устройства дл реализации предлагаемого способа.The drawing shows a diagram of the device for implementing the proposed method.
