Abstract

Abstract: The use of welding of dissimilar materials in the manufacture of different products, both in automobile and civil construction industry, is necessary and understanding the factors that may interfere in the quality of the final product is important for its correct development. So, the main aim of this work was to perform the capacitive welding of different steels, evaluating the effect of different energies on the microstructural evolution and hardness profiles of the welded region. Three different steels were used as base materials (SAE 1045 carbon steel, DOMEX 700MC steel, and DOCOL DP 1000 steel), which were attached to a SAE 10B22 steel pin. To weld, the steels, a bank of capacitors was used, which allows different energies. The characterization of the materials was carried out through hardness verification and metallographic characterization tests. The results show that the capacitive discharge welding process generates a heat-affected zone (HAZ) of short extension, regardless of the type of steel and the average welding energy. For the three types of steel that were used and for the different average welding energies, the microstructure formed in the HAZ was martensite.

SAE 10B22钢与SAE 1045、DOMEX 700MC和DOCOL DP 1000钢的电容焊接

摘要:在汽车和民用建筑行业中，不同材料的焊接在制造不同产品中是必要的，了解可能影响最终产品质量的因素对其正确发展至关重要。因此，本工作的主要目的是进行不同钢的电容焊接，评估不同能量对焊接区显微组织演变和硬度分布的影响。使用三种不同的钢材作为基体材料(SAE 1045碳钢、DOMEX 700MC钢和DOCOL DP 1000钢)，将其固定在SAE 10B22钢销上。为了焊接钢，使用了一组电容器，它允许不同的能量。通过硬度验证和金相表征试验对材料进行表征。结果表明，无论钢的类型和平均焊接能量如何，电容放电焊接过程都会产生一个短扩展的热影响区。三种钢在不同的平均焊接能量下，热影响区形成的组织均为马氏体。

期刊介绍： The Journal Soldagem & Inspeção (S&I) js a techno-scientific journal created in 1995. Printed issues of this journal are distributed free of charge to libraries in Brazil, Latin America and the Iberian Peninsula. It has been printed regularly every quarter since September, 2002, and, since the beginning of 2007, its electronic version is available in the address: (http://www.abs-soldagem.org.br/s&i/). The journal is sponsored by the Brazilian Welding Association (ABS). Since its creation several well known professionals working in welding contributed with the Journal Soldagem & Inspeção and its editorial board crosses the Brazilian borders. During its evolution the Journal received ta special contribution from the Editors-in-chief : Ronaldo Paranhos, Américo Scoti, Paulo Modenesi e Alexandre Bracarence. Since January 2012 the Editor-in-chief is Ana Sofia C. M. D’Oliveira, Full professor at Universidade Federal do Paraná (UFPR) . Her work focus mainly on Hardfacing and Physical Metallurgy. The jornal Soldagem & Inspeção also counts with 10 Associate Editors and a fix Editorial board of referees. short-term (Ad Hoc) referees can be invited to evaluate some papers submitted to the journal. The Soldagem & Inspeção journal is the scientific divulgation channel of the Brazilian Welding Association (ABS). It aims to publish original papers related to the scientific and technological development of welding, inspection, and related fields. Review papers or letters on current and controversial subjects are also published in the Journal. Its abbreviated title is Soldag. insp. (Impr.), which should be used in bibliographies, footnotes and bibliographical references and strips.
