Soldadura de cobre por ultrassons

Abstract

O cobre é um material de extrema relevância, sendo atualmente muito utilizado em enumeras aplicações. Porém, a sua alta condutividade térmica torna o seu processo de soldadura desafiante, dificultando a sua automatização e integração em processos industriais. O presente trabalho visa analisar as características da soldadura de cobre por ultrassons, identificando os parâmetros que maximizem a resistência mecânica de juntas sobrepostas e que assegurem a selagem de tubos. Para tal, foram soldadas chapas de cobre, cujos melhores resultados foram obtidos com um tempo de soldadura de 3 segundos e uma pressão de 6 bar. Foram selados tubos com um tempo de soldadura de 3 segundos e 4 bar.

Copper is a material of extreme importance, currently used in numerous applications. However, its high thermal conductivity makes the welding process challenging, complicating its automation and integration into industrial processes. This study aims to analyze the characteristics of copper welding by ultrasound, identifying the parameters that maximize the mechanical strength of overlapped joints and ensure the sealing of tubes. For this purpose, copper plates were welded, with the best results achieved with a welding time of 3 seconds and a pressure of 6 bar. Tubes were sealed with a welding time of 3 seconds and a pressure of 4 bar.
