The Process of weld brazing CMT (Cold Metal Transfer pulse) for assembly of the different thin sheets

Abstract

This paper describes the experimental program realized for the research of the behavior at the assembly through weld-brazing CMTP (Cold Metal Transfer pulse) of thin sheets of copper with aluminum. Four variants were chosen and studied, settling the best conditions for the assembly. They were made welded samples which were analyzed in volume terms of metallurgical and mechanical structure. It was also analyzed the influence of cooling velocity on the structure.
