Изобретение относитс к области исследовани прочностных свойств материалов, а именно к способам контрол качества соединений , полученных сваркой, в частности сваркой давлением с длительным нагревом.The invention relates to the field of studying the strength properties of materials, in particular, to methods for controlling the quality of joints obtained by welding, in particular by pressure welding with prolonged heating.
По основному авт. св. № 266314 известен способ контрол качества соединени , полученного сваркой (например, сваркой давлением с подогревом).According to the main author. St. No. 266314 discloses a method for controlling the quality of a joint obtained by welding (e.g., pressure welding with heating).
Известный способ обладает тем недостатком , что при его использовании трудно вы вить участки физического контакта, на которых произошло химическое взаимодействие, и участки физического контакта, на которых химического взаимодействи не произошло. The known method has the disadvantage that when it is used, it is difficult to identify the areas of physical contact at which chemical interaction occurred, and the areas of physical contact at which chemical interaction did not occur.
С целью повышени качества контрол образец по предлагаемому способу нагревают при нагружении до температуры, нри которой начинаетс процесс межзеренного разрушени .In order to improve the quality of control, the sample according to the proposed method is heated under loading to a temperature, at which the process of intergranular destruction begins.
Способ заключаетс в следуюш;ем. Изготавливают образец дл механических испытаний, имеюшпй сварное соединение, полученное давлением с подогревом, причем па рабочей части образца создают концентратор напр жени . The method is as follows; A specimen is made for mechanical testing, having a welded joint produced by pressure with heating, and a voltage concentrator is created on the working part of the specimen.
Затем устанавливают образец на испытательную машину, нагревают его до температуры, при которой начинаетс процесс мел зеренного разрушени и нагружают раст жением до разрушени в зоне концентратора напр жений . Далее изготавливают шлиф образца из зоны сварного соединени , по которому контролируют качество соединени , полученного сваркой.The sample is then placed on a testing machine, heated to a temperature at which the process of grain disintegrating chalk begins, and loaded by stretching until destruction in the area of the stress concentrator. Next, make a thin section of the sample from the zone of the welded joint, which controls the quality of the joint obtained by welding.
Так вы вл ютс участки, в которых металл сплошной, то есть участки физического контакта , на которых произошло химическое взаимодействие и участки физического контакта, на которых химического взаимодействи не произошло.Thus, the areas in which the metal is solid, i.e. the areas of physical contact at which chemical interaction occurred and the areas of physical contact at which chemical interaction did not occur, are detected.
Предмет изобретени Subject invention
Способ контрол качества соединени , полученного сваркой, по авт. св. № 266314, отличающийс тем, что, с целью повышени качества контрол , образец при нагружении нагревают до температуры, при которой начинаетс процесс межзеренного разрушени .The method of quality control of the welded joint according to the author. St. No. 266314, characterized in that, in order to improve the quality of control, the sample is heated to a temperature at loading, at which the process of intergranular fracture begins.
