Soldadura de cobre com robot de soldadura

Abstract

O objetivo principal desta dissertação foi investigar e otimizar os parâmetros de soldadura para o cobre utilizando um robot de soldadura MIG, avaliando a viabilidade e eficiência deste processo em aplicações industriais, como bombas de calor e sistemas de refrigeração. A metodologia incluiu ensaios experimentais para ajustar trajetórias do robot, definição de parâmetros como intensidade de corrente, tensão, velocidade de soldadura e análise das propriedades das juntas através de testes de estanquidade e análises micrográficas. Os resultados indicaram que, embora o processo apresente desafios relacionados à elevada temperatura de fusão do cobre e à necessidade de precisão nos parâmetros, foi possível obter soldaduras com características satisfatórias de estanquidade e penetração. Conclui-se que o método é promissor, mas requer otimizações adicionais para aplicação em escala industrial. Este estudo contribui para o avanço do conhecimento na automação da soldadura MIG aplicada ao cobre, com potencial impacto na melhoria da eficiência e qualidade na produção industrial.

The main objective of this dissertation was to investigate and optimize the welding parameters for copper using a MIG welding robot, assessing the feasibility and efficiency of this process in industrial applications, such as heat pumps and refrigeration systems. The methodology included experimental trials to adjust the robot's trajectories, define parameters such as current intensity, voltage, welding speed, and analyze the joint properties through leakage tests and micrographic analyses. The results indicated that, although the process presents challenges related to the high melting point of copper and the need for precise parameters, it was possible to achieve welds with satisfactory leakage resistance and penetration characteristics. It is concluded that the method is promising but requires further optimization for industrial-scale application. This study contributes to advancing knowledge in the automation of MIG welding applied to copper, with potential to improve efficiency and quality in industrial production.
