Abstract

Patente de Invenção: <B>"GáS INERTE PARA SOLDAGEM TIG"<D>. A invenção refere-se a um gás protetor para soldagem TIG de metais, especialmente aços de alta liga ou de baixa liga, cuja condutividade térmica seja menor que a do alumínio. O gás da invenção consiste em argónio, hélio e hidrogênio e permite melhoras significativas a serem feitas na estabilidade do arco elétrico, na velocidade da soldagem, oxidação da superfície da solda e área adjacente, performance de fluxo e aparência da solda.
