Abstract

<B>"Processo de solda ou de corte de plasma ou TIG com gás não oxidante com reduzido teor de impurezas H~ 2~O e/ou O~ 2~. A presente invenção refere-se por um lado um processo de tralho com arco elétrico, como um processo de corte de plasma ou de solda TIG, na qual alimenta-se um maçarico ao menos com gás não oxidante, sendo que o maçarico está provido ao menos de um eletrodo de metal puro ou com liga, como um eletrodo de tungstênio, caracterizado pelo fato de que o referido gás oxidante contém uma proporçao de impurezas do tipo oxigênio (O~ 2~) inferior a 80 ppmv e uma proporção de impurezas do tipo vapor d'água (H~ 2~O) inferior a 400 ppmv e por outro lado abrange um gás de solda deste tipo.
