Abstract

ser de peças metálicas, na qual a área a ser soldada é encerrada em um gás de processo. De acordo com a invenção, uma mistura de pelo menos um gás nobre (preferencialmente hélio) e pelo menos 0,5% de volume de nitrogênio é usada como gás de processo. A invenção aperfeiçoa a qualidade da junta soldada especialmente em materias de alumínio e aços com constituintes estruturais austeníticos.
