Sažetak: | Increasing globalization and technological developments have progressively demanded companies to seek cost reductions and higher competitiveness, productivity, and quality in products manufactured and marketed. The search for materials with high mechanical resistance and low weight is a mandatory requirement in this setting, and it is no different in metallurgy. Aluminum and its alloys come as great alternatives to meet those demands. Choosing a type of material that will adapt and meet the requirements imposed by aluminum-made equipment, most often occurs without a detailed study on property and process conditions. Welding is one of the most important manufacturing processes in the industry. Thus, an assessment is made of a welded joint of the alloy 5083-o, through the Automated Pulsed MIG (Metal Inert Gas) process. The aluminum welding, mentioned by Mathers, (2002) as difficult, is due to the formation of porosity in the weld bead. This work presents a study on the use of preheating to reduce porosity. The test specimens were manufactured, welded, and analyzed in welding laboratories at the University Foundation of Passo Fundo (UPF), RS, Brazil. The material used were aluminum sheets 5083-O with thickness of 6 mm, length of 250 mm, and width of 120 mm. Welding was performed in a robotic cell with an OTC SUMIG robot with OTC Digital Inverter DP 400 welding source, a device was used to attach the test specimens, and welding was performed by Ceramic Backing. Parameters of welding speed, amperage, voltage, and gas flow were kept at a fixed rate for all welds. On the other hand, preheating temperature and shielding gas were varied. The shielding gases used were 100% argon, and a mix of 75% argon and 25% helium. Test specimens were submitted to preheating at 120 ˚C, preceding each welding. The main objective of this work is to use the techniques mentioned for reducing porosity in the weld bead of specimens analyzed. The reduction of the porosity will be a parameter to increase the strength of welded joints. The porosity analysis was performed using an X-ray microtomógrafo. The test results for the reduction in porosity were satisfactory because the amount of pores was lower with use of argon and helium mixture but since the use of the preheating can not be said that it was beneficial to use the results. The mechanical strength of the joints was affected by adding material having less strength than the base metal |

The mechanical strength of the joints was affected by adding material having less strength than the base metalA globalização e o avanço tecnológico crescente têm obrigado cada vez mais as indústrias a buscarem redução nos custos e aumento na competitividade, produtividade e qualidade do produto. A busca por materiais que possuam ótima resistência mecânica e baixo peso é um requisito obrigatório nesse cenário. O alumínio e suas ligas aparecem como ótimas alternativas para satisfazer tais exigências. Desta forma, este trabalho realiza avaliação de uma junta soldada da liga AA5083-O por meio do processo MIG (metal inert gas) Pulsado Automatizado. A soldagem do alumínio, citada por Mathers (2002) como dificultosa, é assim considerada pela grande formação de porosidade no cordão de solda. Os corpos de prova foram fabricados, soldados e analisados nos laboratórios de soldagem da UPF. O material utilizado consistiu em chapas de alumínio 5083-O, com espessura de 6 mm, 250 mm de comprimento e 120 mm de largura, cortadas no sentido de laminação da chapa. A soldagem foi realizada em uma célula robotizada, com um robô da marca OTC SUMIG, com fonte de soldagem OTC Digital Inverter DP 400 e com auxilio de um dispositivo de fixação, ainda foram utilizados backing cerâmico para o aporte do metal líquido na raiz do cordão de solda. Os parâmetros de velocidade de soldagem, amperagem, voltagem e vazão de gás foram mantidos em todas as condições avaliadas, tendo a temperatura de pré-aquecimento e gás de proteção como condições alteradas. Os gases de proteção utilizados foram argônio 100% e uma mistura de argônio 75% e hélio 25%. Os corpos de prova das condições "B" e "D" foram submetidos a pré-aquecimento de 120ºC, antecedendo cada execução de solda os corpos das condições "A" e "C" foram soldados sem pré-aquecimento. A análise e quantificação da porosidade foi realizada com auxílio de um microtomógrafo de raio-X. Os resultados dos ensaios para a redução da porosidade foram satisfatórios pois, a quantidade de poros foi menor com a utilização da mistura de argônio e hélio porém com a utilização do pré-aquecimento a quantidade de poros não foi alterada. A resistência mecânica das juntas foi prejudicada pelo material de adição possuir resistência mecânica menor que o metal de base.Universidade de Passo FundoEngenhariaBRUPFPrograma de Pós-Graduação em Projeto e Processos de FabricaçãoIsrael, Charles Leonardohttp://lattes.cnpq.br/7302070158208102Marco, Carlos Gustavo de2025-05-07T18:08:37Z2014-09-29info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfMARCO, Carlos Gustavo de.
