Abstract

Resumo O presente trabalho tem como objetivo obter uma ferramenta computacional para estimar os principais parâmetros do processo FSSW para a industria de construcao naval, utilizando uma abordagem em dois estagios, usando os Metodos de Volumes finitos e Elementos Finitos em dominios com simetria de revolucao. Soldas experimentais foram realizadas em duas placas de liga de aluminio AA6082 com 3mm de espessura. Da comparacao entre os resultados numericos e experimentais, as temperaturas maximas de 423°C estiveram proximas as reportadas pela literatura. Porem, as medidas experimentais foram afetadas pela posicao dos termopares embutidos no suporte de aco, medindo valores maximos inferiores, de 302°C. Os campos de velocidades circunferenciais e suas zonas de altos gradientes foram coincidentes com a zona de mistura revelada no ataque metalografico. A tecnica, nao obstante, foi bem sucedida apesar das simplificacoes adotadas.

一种简化的计算FSSW的两种模型方法

摘要本研究的目的是获得一种计算工具来估计造船工业FSSW工艺的主要参数，采用两步方法，使用有限体积法和旋转对称域的有限元法。在两块3mm厚的AA6082铝合金板上进行了实验焊接。通过数值和实验结果的比较，423°C的最高温度接近文献报道的温度。然而，实验测量受到aco支架内热电偶位置的影响，测量的最大值较低，为302°C。圆周速度场及其高梯度区与金相侵蚀中发现的混合区一致。然而，尽管采用了简化方法，这项技术还是成功的。

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.
