Description
(54) СПОСОБИСПЫТАНИЯ НА ПРОЧНОСТЬ МАТЕРИАЛА ЗОНЫ СВАРНОГО ШВА(54) METHODOLOGY FOR THE STRENGTH OF THE MATERIAL WELDED ZONE
II
Изобретение относитс к области испытани материалов и соединений, в частности к способам испытани на про чность материала зоны сварного шва.The invention relates to the field of testing materials and joints, in particular to methods for testing the strength of the material of the weld zone.
Известен способ испытани на прочность материала зоны сварного шва, заключающийс в том, что образец со сварным швом нагружают кручением до разрушени и регистрфуют при этом угол закручивани Г13There is a known method for testing the strength of the material of the weld zone, which consists in loading the sample with the weld by torsion until it breaks and registering the twist angle G13.
Недостатком известного способа в л етс низка точность определени момента растрескивани материала зоны сварного шва.The disadvantage of this method is the low accuracy of determining the moment of cracking of the material of the weld zone.
Цель изобретени - повышение точнести определени момента растрескива НИН.The purpose of the invention is to increase the accuracy of determining the moment of cracking NIN.
Указанна цель достигаетс тем, что используют призматический образец, за крепл ют его консольно, на боковую грань нанос т сварной шов так, чтобы лини сплавлени совпадала с серединой этой грани, а кручение образца осуществл ют сначала в одном .направлении, а.This goal is achieved by using a prismatic sample, fastening it with a cantilever, welding is applied to the side face so that the fusion line coincides with the center of this face, and the sample is twisted first, in one direction, as well.
.ПОТОМ в противоположном направлении на вдвое болыиий угол..,. Then in the opposite direction at twice the big angle ..,
На чертеже изображена схема осуществлени способа испытани .The drawing shows a flow chart of the test method.
Способ осуществл етс следуюищм образом.The method is carried out in the following manner.
Призматический образец 1 вырезают из листа в направлении прокатки А и закрепл ют его консольно. На боковую грань образца нанос т сварной шов 2 в виде сварочного ва нка, накладыва его так, чтобы лини сплавлени П-П совпадала с серединой этой грани. Затем образец 1 нагружают 1фучением снача ла в одном нШ1равленш1, а потом в противоположном на вдвое больший угол. При кручений образца 1 максимальные касательные ншф жени возникают в середине боковой грани, т.е. у лини сплавлени . При исходном кручении материал сварной зоны упрочн етс , а при кручении в гфотивоположном направ -, лении эффективность наклепа возрастает и в силу невысокой пластичности мате- .The prismatic sample 1 is cut out from the sheet in the rolling direction A and is secured with a cantilever. A weld seam 2 in the form of a welding rod is applied to the side face of the sample, applying it in such a way that the fusion line P – P coincides with the center of this face. Then, the sample 1 is loaded by first pressing in one of the first and then in the opposite one at twice the angle. For torsion of sample 1, the maximum tangent nspings arise in the middle of the side face, i.e. at the fusion line. At the initial torsion, the material of the welded zone is strengthened, and at the torsion in the opposite direction, the efficiency of the work hardening also increases due to the low ductility of the material.
