Title in Portuguese
Análise da transferência metálica na soldagem a arco elétrico com eletrodo revestido.
Keywords in Portuguese
Soldagem a arco
Abstract in Portuguese
Este trabalho analisa a transferência metálica na soldagem com eletrodo revestido em função dos tipos de revestimento e parâmetros de soldagem. Inicialmente são feitas algumas considerações a respeito dos tipos de forças que podem agir no processo e dos tipos de transferência metálica. A seguir é feito um resumo das técnicas experimentais utilizadas para estudar a transferência metálica e, a partir daí, definida a técnica utilizada neste trabalho. Foram feitas 192 experiências variando-se o tipo de revestimento e os parâmetros de soldagem. Finalmente é feita a discussão dos resultados mais significativos em função do diâmetro característicos da gota e da quantidade de respingos e correlacionados com o desempenho do eletrodo.

Abstract in English
The subject of this work is analysing the metal transfer in shielded metal arc welding related with the type of electrode coverings and welding parameters. Initially, some general aspects about the forces acting during the process and the type of metal transfer are presented. Next a summary of the metal transfer techniques used is made and then the techniques utilized in this work is defined. 192 experiments were carried out chaging the type of electrode covering and welding parameters. Finally a discussion on the significant results is made trying to correlate the effects of electrode covering and welding parameters on the electrode performance.
