Abstract

Данная работа посвящена исследованию влияния активирующих флюсов на основе фторидов на структуру сварного шва, сваренного на стальных пластинах марки 08Х18Н10Т. Задачи, которые решались во время исследования: 1. Изучение литературных источников на заданную тематику; 2. Подготовка и проведение эксперимента; 3. Анализ результатов. Работа проведена на базе ООО «Алюарт», где производилась подготовка и проведение эксперимента: подготовка пластин перед сваркой, приготовление необходимых составов активирующих флюсов, сварка образцов, вырезка части сварных швов, зачистка после сварки. Далее была сделана шлифовка и травление вырезанных образцов для определения макроструктуры, микроструктуры и твердости по Виккерсу. В результате эксперимента были проанализированы: 1. Внешний вид сварных швов и их кратеров (размеры и форма). 2. Поведение дуги и сварочной ванны во время процесса сварки. 3. Очищающаяся способность активирующего флюса и шлака с пластин после сварки. 4. Данные макро- и микроструктуры. 5. Глубина проплавления и форма глубины проплавления. 6. Данные измерений твердости по Виккерсу. Актуальностью данной работы является способность активирующих флюсов воздействовать на проплавляющую способность дуги и на минимальных токах получать большую глубину проплавления.

This work is devoted to the study of the effect of fluoride-based activating fluxes on the structure of a welding seam on 08X18H10T steel plates. Tasks that were solved during the study: 1. The study of literary sources on a given topic; 2. Preparation and conducting of the experiment; 3. Analysis of the results. The work was carried out on the basis of Aluart LLC, where following steps were taken to prepare for the experiment: preparation of plates before welding, preparation of the required compositions of activating fluxes, welding of samples, cutting of a part of welds, stripping after welding. Next, the cut samples were sanded and etched to determine the macrostructure, microstructure and Vickers hardness. As a result of the experiment, the following factors were analyzed: 1. The visual appearance of welding seams and their craters (size and shape). 2. The behavior of the arc and the welding bath during the welding process. 3. The cleaning ability of the activating flux and slag from the plates after welding. 4. Macro- and microstructure data. 5. The penetration depth and the shape of the penetration depth. 6. Vickers hardness measurement data. The relevance of this work is the ability of activating fluxes to affect the melting ability of the arc and obtain a large penetration depth at minimum currents.
