Изобретение относитс к способам ультразвукового не разрушающего контрол и может быть использовано при контроле сварного соединени трением в процессе его производства.The invention relates to non-destructive ultrasonic testing methods and can be used to control a welded joint by friction during its production.
Известен способ контрол качества сварного соединени , заключающийс в том, что в зону сварки ввод т импульсы ультразвуковых колебаний и регистрируют в : роцессе сварки амплитуду эхо-сигналов П).A known method for controlling the quality of a welded joint is that impulses of ultrasonic vibrations are introduced into the welding zone and are recorded in the welding process: the amplitude of the echo signals II).
Однако таким способом нельз вести контроль качества сварного соединени , производимого трением.However, in this way, it is not possible to control the quality of a welded joint produced by friction.
Целью изобретени вл етс обеспечение контрол качества сварного соединени при свдрке трением.The aim of the invention is to ensure the quality control of a welded joint during friction friction.
Цель достигаетс тем, что фиксируют момент по влени и величину максимальной амплитуды эхо-сигнала и момент ее стабилизации, и по ним суд т о качестве сварного соедииени .The goal is achieved by fixing the moment of occurrence and magnitude of the maximum amplitude of the echo signal and the moment of its stabilization, and judging by it the quality of the welded joint.
Кроме того, с целью повышени адезкносга о контрол , дополнительно репктрируют йзмене- ки во времени моментов сил трени , а о качестве сварки суд т в моменты совпаде1ш стабилизацин амплитуды прин того эхо-сигналаIn addition, in order to improve the control of the control, additional moments of frictional forces are replicated over time, and the quality of welding is judged at times of stabilization of the amplitude of the received echo signal
ультразв тсовых колебаний и моментов сил трени .Ultrasonic vibrations and moments of friction.
На фиг. 1 показана зависимость момента сил трени М (т) и амплитуды эхо-сигнала ультразвуковых колебаний А (т} от времени сварки; на фиг. 2 - схема реализации способа контрол качества сварного соединени при сварке трением.FIG. Figure 1 shows the dependence of the frictional moment M (t) and the amplitude of the echo signal of ultrasonic oscillations A (t) on the welding time; Fig. 2 shows a scheme for implementing a method for controlling the quality of a welded joint in friction welding.
Способ осуществл етс следующим образом.The method is carried out as follows.
В деталь 1 посредством излучающего преобразовател 2 ввод т импульсы ультразвуковых колебаний, которые, отразившись от плоскости соединени деталей 3 и , принилиютс приемным преобразователем 4.In part 1, pulses of ultrasonic vibrations are introduced by means of a radiating transducer 2, which are reflected from the plane of connection of parts 3 and are received by the receiving transducer 4.
Далее в процессе сварки регистрируют во времени амплитуды эхо-сигналов от момента максимума до момента стабилизации точки С-Е на кривой А (т}, фиксируют момент достижени максимальной величины амплитуды зхо-сигналов и момент ее стабилизации, и по ним суд т о качестве сварного соединени .Further, in the process of welding, the amplitudes of the echo signals are recorded in time from the moment of maximum until the point of stabilization of point C – E on curve A (m), the moment of reaching the maximum amplitude of the echo signals and the moment of its stabilization are recorded, and the quality of the welded compounds.
