Изобретение относитс к сварке, преимущественно точечной, и может найти нр менение в самолетостроении и дрибо.ростроении.The invention relates to welding, mainly spot welding, and can be found in aircraft manufacturing and driving industry.
Известные способы неразрушающего контрол сварных соединений характеризуютс низкой точностью измерений.Known methods of non-destructive testing of welded joints are characterized by low measurement accuracy.
По предлагаемому способу, с .целью повышени точности и быстродействи контрол , до контакта со швом измен ют температуру чувствительного элемента. Это позвол ет снизить исходную температуру нагрева элемента и уменьшить пропускаемый через сва:рную точку тепловой поток, дол которого, проход ща через сварную точку .0 нижний лист, возрастает, что увеличивает точность измерений .In the proposed method, in order to improve the accuracy and speed of control, the temperature of the sensing element is changed before contact with the seam. This allows the initial heating temperature of the element to be reduced and the heat flux passed through the core point, the fraction of which passing through the weld point .0 the lower sheet increases, which increases the measurement accuracy.
Предлагаемый способ заключаетс в том, что к контролируемой сварной точке прижимают чувствительный элемент термоизмерительного устройства, который предварительно нагревают (или охлаждают) до температуры , отличной от температуры точки, а о -качестве сварки суд т по времени изменени температуры этого чувствительного элемента, иапример на посто нный интервал температур, непосредственно примыкающий к температуре предварительного нагрева чувствительного элемента.The proposed method consists in pressing a sensitive element of a thermo-measuring device to a controlled weld point, which is preheated (or cooled) to a temperature different from the point temperature, and the quality of welding is judged by the time of temperature change of this sensitive element. This is a temperature range immediately adjacent to the preheating temperature of the sensing element.
Предмет изобретени Subject invention
Способ неразрущающего .контрол сварного шва путем пропускани через шов теплового потока с последующей регистрацией с помощью контактного термоизмерительного прибора изменени температуры шва, отличающийс тем, что, с целью повышени точности и быстродействи контрол , до контакта со щвом измен ют температуру чувствительного элемента до температуры, отличной от температуры щва, а о качестве сварки суд т по :времени изменени температуры этого чувствительного элемента.The method of non-destructive weld inspection by passing a heat flux through the weld and then registering with the help of a contact thermometer a change in the weld temperature, characterized in that, in order to improve the accuracy and speed of control, the temperature of the sensing element is changed to a temperature different from the temperature of the weld, and the quality of welding is judged by: the time of temperature change of this sensitive element.
