Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This study aims to investigate the influence of cooling rate on API 5L-X80 steel, extracted from a circular section of pipeline, welded using the automated MAG process with two wires, one solid and one tubular metal-cored wire. To obtain different cooling rates, five different preheating temperatures were used. Double V bevels with noses were then welded at five different preheating and interpass temperatures. The mechanical and metallurgical properties of the welded bevels were evaluated using tensile, bending, impact (Charpy-V), and hardness (Vickers) tests. The results of the mechanical tests were higher than the minimums defined by the standard, with very interesting results. There was a good correlation between the hardness, tensile, and impact tests. The mechanical tests and metallurgical analyses showed that the combined effect of time and temperature created significant changes in the results. The mechanical properties of the welded joints were higher than the minimum requirements of the API 5L standard.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - El presente trabajo tiene como objetivo estudiar la influencia de la velocidad de enfriamiento sobre un acero API 5L-X80, extraído de una sección circular de tubería, soldado con el proceso MAG automatizado y con dos alambres, uno macizo y otro tubular con alma metálica. Para obtener diferentes velocidades de enfriamiento, se utilizaron cinco precalentamientos distintos. A continuación, se soldaron, con cinco temperaturas diferentes de precalentamiento y entre pasadas, chaflanes dobles en V con punta. Sobre los chaflanes soldados, se evaluaron las propiedades mecánicas y metalúrgicas con ensayos de tracción, flexión, impacto (Charpy-V) y dureza (Vickers). Los resultados de los ensayos mecánicos fueron superiores a los mínimos definidos por la norma, con resultados muy interesantes. Hubo una buena correlación entre los ensayos de dureza, tracción e impacto. Los ensayos mecánicos y los análisis metalúrgicos demostraron que el efecto combinado del tiempo y la temperatura provocó grandes cambios en los resultados. Las propiedades mecánicas de las juntas soldadas fueron superiores a los mínimos exigidos por la norma API 5L.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Le présent travail vise à étudier l'influence du taux de refroidissement sur un acier API 5L-X80, extrait d'une section circulaire de conduit, soudé avec le procédé MAG automatisé et avec deux fils, un fil massif et un fil tubulaire à âme métallique. Afin d'obtenir différents taux de refroidissement, cinq préchauffages distincts ont été utilisés. Ensuite, des chanfreins doubles en V avec nez ont été soudés à cinq températures différentes de préchauffage et d'interpasse. Sur les chanfreins soudés, les propriétés mécaniques et métallurgiques ont été évaluées à l'aide d'essais de traction, de flexion, de choc (Charpy-V) et de dureté (Vickers). Les résultats des essais mécaniques ont été supérieurs aux minimums définis par la norme, avec des résultats très intéressants. Il y avait une bonne corrélation entre les essais de dureté, de traction et d'impact. Les essais mécaniques et les analyses métallurgiques ont démontré que l'effet combiné du temps et de la température a entraîné des changements importants dans les résultats. Les propriétés mécaniques des joints soudés étaient supérieures aux minimums requis par la norme API 5L.…
