Influência dos Parâmetros de Soldagem em Tubos de Alumínio AA6063 pelo Processo CDFW

Abstract: Resumo Neste trabalho realizou-se um estudo das interações entre as variáveis do processo de soldagem por atrito, conhecido como Continuous Drive Friction Welding (CDFW) em junção de tubos de alumínio AA6063, com diâmetro de 12,7 mm e espessura de 1,59 mm. Foi analisada a influência das variáveis: rotação, pressão de atrito e tempo de atrito nas dimensões finais da rebarba e comprimento da peça soldada. O número de experimentos realizados foi definido por planejamento fatorial completo (3k), onde cada variáve… Show more

“…Segundo Braguine et al (2018), a análise de Pareto visa identificar quais parâmetros são responsáveis pelos efeitos mais significativos, e os resultados das análises de qualidade de água contemplados no índice de qualidade de água (IQA) foram avaliados de acordo com a análise de pareto. Dos nove parâmetros que compõe o IQA, evidenciou-se que os parâmetros sólidos totais e turbidez juntos, influenciam 71,2%, sobre a qualidade da água na área estudada.…”

“…The use of aluminum is due to its weight, since it is lighter when compared with other metals, and because AA 6063 presents an electrical conductivity that satisfies the projects of companies such as the electric energy segment, consumers of this kind of product. Among studies such as [4][5][6][7], special attention has been given to the welding of different aluminum alloys, whose usage by the energy industry is extremely intense due to good corrosion resistance, good mechanical properties and excellent electrical conductivity. Aluminum welding is a really complex task and requires well defined parameters to present a satisfactory result, with no defects such as porosity, cracks, lack of penetration, lack of fusion, filling failures, etc.…”

“…Furthermore, in [9], an experimental design is presented for a GMAW welding process to maximize the amount of information with the following characteristics: response surface-based modelling (RSM) to quantify response variables of interest; statistical model selection to obtain the most informative models; statistical model checking for definitive models to ensure inference capabilities; and multiobjective optimization to identify the Pareto front of optimal solutions. Several papers found in literature [5,6,[9][10][11][12] use techniques such as factor analysis, normal boundary intersection (NBI) and RSM for multiobjective optimization. However, they combine NBI and multivariate mean square error (MMSE), disregarding multivariate constraints.…”
