Изобретение относитс к области машиностроени , в частности к област материалов и изделий, и предназначаетс дл усовершенствовани методов изучени вли ни сварочных дефектов на прочность стальных изделий .The invention relates to the field of engineering, in particular to the field of materials and products, and is intended to improve the methods of studying the effect of welding defects on the strength of steel products.
Наибо.лее близким по технической сущности вл етс способ создани искусственного дефекта, имитирующего сварочный дефект типа пор путем высверливани в металле шва сварного образца глухого отверсти заданной глубины и таметра 1 .Однако известный способ не позвол ет в полной мере оценить прочность сварного соединени со сварочными дефектами, так как результаты исследований по вы влению вли ни дефектов на прочность сварных соединений, производимых на металле с искусственно создаваекыми механической обработкой дефектами, вл ютс весьма условными в св зи с тем, что искусственное создание дефектов (обработка лезвийным инструментом) неизбежно приводит к наклепу металла и создани в св зи с этим .остаточных напр жений что может в сильной степени исказитьThe closest in technical essence is a method of creating an artificial defect that simulates a welding pore-type defect by drilling a welded sample of a blind hole of a predetermined depth and tureter 1 in a weld metal. However, the known method does not fully evaluate the strength of a welded joint with welding defects because the results of studies on the influence of defects on the strength of welded joints produced on metal with artificially machined defects are quite conventional in connection with the fact that the creation of artificial defects (processing blade tool) inevitably leads to work hardening of the metal and create a bond with this .ostatochnyh stresses that can strongly distort

Целью изобретени вл етс обеспечение более полной имитации в образце дефекта.The aim of the invention is to provide a more complete imitation of the defect in the sample.
