A method of joining the ends of metal strip material together by positioning a consumable insert of weld filler material between the full thickness of the strip ends and below the lower surface of the strip ends a predetermined depth to establish a predetermined gap between the strip ends thus allowing for full arc penetration of the strip ends and providing a supply of the filler material to the root of the weld to be formed between the strip ends.
L'invention porte sur un procédé d'aboutage de bandes de métal par mise en place d'un insert consommable de matériau d'apport sur toute l'épaisseur des extrémités de la bande et se prolongeant sous la surface inférieure des extrémités de la bande sur une épaisseur déterminée de manière à former entre les extrémités de la bande un intervalle prédéterminé permettant une pénétration totale de l'arc entre les extrémités de la bande et assurant la pénétration du matériau d'apport jusqu'à la racine de la soudure devant être formée entre les extrémités de la bande.
