Abstract

Tuyère d’apport de gaz de protection pour torche de soudage. L’invention concerne une torche de soudage (10), comprenant : - une électrode (11) s’étendant le long d’un axe longitudinal (X) et destinée à former un arc électrique avec une pièce à souder, - une tuyère (12) agencée autour de l’électrode, de préférence de manière coaxiale, en étant en retrait longitudinal par rapport à l’électrode, la tuyère étant configurée pour éjecter un gaz de protection, dit gaz externe, s’écoulant hors de la tuyère en étant attaché le long de la surface externe de l’électrode jusqu’à l’extrémité libre de l’électrode en saillie hors de la tuyère. Figure pour l’abrégé : fig.5
