Цель изобретени  - расширение функциональных возможностей за счет обеспечени  контрол  различных характеристик сварного соединени . В способе измер ют твердость материала сварного соединени  и твердость основного материала, сравнивают ширины зон термического вли ни  образца-свидетел  и испытуемого образца и по разнице ширины зон оценивают тепловложени The invention relates to the welding of metals and can be used to control the quality of welded joints undergoing structural transformations during heat treatment. The purpose of the invention is to enhance the functionality by controlling the various characteristics of the welded joint. In the method, the hardness of the material of the welded joint and the hardness of the base material are measured, the widths of the heat-affected zones of the witness sample and the test specimen are compared, and the input heat is estimated from the difference of the widths of the zones

Description

Изобретение относитс  к сварке металлов и может быть использовано дл  контрол  качества сварных соединений, полученных электродуговой сваркой из материалов , претерпевающих структурные превращени  при термообработке.The invention relates to the welding of metals and can be used to control the quality of welded joints produced by electric arc welding from materials undergoing structural transformations during heat treatment.

Цель изобретени  - расширение функциональных возможностей за счет обеспечени  контрол  различных характеристик сварного соединени .The purpose of the invention is to enhance the functionality by controlling the various characteristics of the welded joint.

Способ реализуетс  следующим образом .The method is implemented as follows.

На готовом сварном соединении измер ют распределение твердости и устанавливают , что на рассто нии 5 мм от линии сплавлени  твердость соответствует твердости основного металла. Таким образом, ширина зоны термического вли ни  равна 5 мм. Сравнение с образцом-свидетелем показало , что их зоны термического вли ни On the finished welded joint, the distribution of hardness is measured and it is established that at a distance of 5 mm from the fusion line the hardness corresponds to the hardness of the base metal. Thus, the width of the heat affected zone is 5 mm. Comparison with the sample-witness showed that their heat affected zones

равны, и следовательно, тепловложение при сварке было идентичным, т е технологи  сварки была соблюдена.equal, and therefore, the heat input during welding was identical, te welding technology was followed.

Образец-свидетель дл  каждого материала готовитс  заранее. На нем отрабатываетс  техно :оги  сварки и измер етс  ширина зоны термического вли ни . Формула изобретени  Способ технологического контрол  сварного соединени , заключающийс  в том, что измер ют твердость материала сварного соединени  и определ ют ширину зоны термического вли ни  по тарировоч- ной зависимости, отличающийс  тем, что, с целью расширени  функциональных возможностей, дополнительно измер ют твердость основного металла, сравнивают ширину зоны термического вли ни  с той же зоной образца-свидетел  и оценивают тепловложение по разности ширины зон.A witness sample for each material is prepared in advance. Techno technology is worked out on it, welding points and the width of the heat affected zone is measured. Claims The method of technological control of a welded joint, which consists in measuring the hardness of the material of the welded joint and determining the width of the heat-affected zone based on the calibration dependence, characterized in that, in order to extend the functionality, the hardness of the base metal is additionally measured , compare the width of the heat affected zone with the same zone of the witness sample and estimate the heat input by the difference of the width of the zones.
