Cette Note présente deux méthodes d'amélioration de la pénétration des cordons de soudure en procédé TIG en optimisant la géométrie d'un dépôt de silice à la surface des pièces à assembler. L'étude porte sur un acier de type bas carbone (type S235) et sur un alliage d'aluminium 5086. Alors que pour l'acier un dépôt couvrant entièrement le joint entre les pièces améliore sensiblement la pénétration, dans le cas de l'aluminium, les cordons les plus pénétrés sont obtenus en laissant une zone vierge de silice au niveau du joint.

This Note presents ways to improve the weld penetration potential of TIG process by optimising silica application around the joints in a plain carbon steel and an aluminium alloy 5086. Whereas for plain carbon steels, full coverage of joint improves penetration, the presence of a blank zone around the joint in the flux coating on aluminium 5086 using AC-TIG seems to be the best solution for cosmetic and deep welds.
