Abstract

La présente invention concerne un bec de chalumeau (1) pour un chalumeau de soudage, comprenant un corps de base (2) qui présente une électrode non fusible (7) entourée par une buse de contact (6). Un manchon d'isolation (8) et une alimentation en gaz de soudage (9) sont placés entre ladite électrode (7) et ladite buse de contact (6). Ledit bec de chalumeau comprend également une buse à gaz (3) qui entoure la buse de contact (6) et qui présente un filetage interne (4) permettant de la visser sur un filetage externe correspondant (5) sur le corps de base (2), ainsi qu'une surface de butée (11) inclinée et annulaire, qui permet un appui sur une surface correspondante (12) de la buse à gaz lorsque celle-ci est vissée. Une alimentation en gaz protecteur (10) est placée entre ladite buse à gaz (3) et ladite buse de contact (6). L'objectif de la présente invention est de mettre au point un bec de chalumeau (1) avec lequel les pièces d'usure peuvent être remplacées particulièrement facilement et peuvent être mises en place de manière particulièrement optimale. A cette fin, la surface de butée (11) inclinée et annulaire est adjacente au filetage externe (5) sur le corps de base (2). La buse de contact (6) présente en son intérieur des zones (21), par exemple des nervures, qui permettent de centrer le manchon d'isolation (8).
