Description
В плите 1 выполн ют аазделку в виде двух граней 2 и 3, расположенных под углом 60-90® по отношению друг к другУ, В кореньразделки нанос т аус1 енитный сварной шов 4 по исследуемому режил5У и вывод т часть 5 его на одну из граней, например 2. Угол меж ду осью разделки и осью выведенной части 5 сварного шва 4 определ ют по требуемой величине коэффициента концентрации . Трещины в зоне сплавлений образуютс по длине шва за счет отрыва сварного шва 4 от грани 3, выход т на поверхность шва 4, легко обнаруживаютс и измер ютс . Так как размер трещин достаточно велик и они расположены вдоль длины шва в зоне сплавлени , то повышаетс достоверность испытаний.In slab 1, there is an axle made in the form of two faces 2 and 3, angled 60-90® relative to each other. An austenite weld 4 is applied to the root of the cut along the test path and the part 5 is brought to one of the faces, For example, 2. The angle between the axis of the groove and the axis of the withdrawn part 5 of the weld 4 is determined by the required value of the concentration ratio. Cracks in the fusion zone are formed along the length of the seam due to the separation of the weld 4 from the face 3, go to the surface of the seam 4, are easily detected and measured. Since the size of the cracks is quite large and they are located along the length of the weld in the fusion zone, the reliability of the tests increases.
