Title (EN) SEAMLESS WIRE CONTAINING WELDING FLUX
(FR) FIL SANS SOUDURE CONTENANT DU FLUX DE SOUDURE
(JA) 溶接用フラックス入りシームレスワイヤ
Abstract:
(EN) This seamless wire containing welding flux is formed by filling a steel sheath with flux, the amount of Fe in the flux per total mass of the wire being 2-15 mass%, and the flux filling ratio being 10-30 mass%. When the amount (mass%) of Fe in the flux per total mass of the wire is X and the flux filling ratio (mass%) is Y, expression (1) is satisfied. By means of this seamless wire containing welding flux, variation in the flux cross-sectional area relative to the wire cross-sectional area, which is caused by a reverse airflow generated during a diameter reduction step, is reduced, and wire breakage during the diameter reduction step is prevented. Y > −2X + 19 (1)
(FR) L'invention concerne un fil sans soudure contenant du flux de soudure qui est formé par remplissage d'une gaine d'acier avec un flux, la quantité de Fe dans le flux par masse totale du fil étant de 2 à 15 % en masse, et le rapport de remplissage de flux étant de 10 à 30 % en masse. Quand la quantité (% en masse) de Fe dans le flux par masse totale du fil est X et que le rapport de remplissage de flux (% en masse) est Y, l'expression (1) est satisfaite. Au moyen de ce fil sans soudure contenant du flux de soudure, une variation de la surface de section transversale de flux par rapport à la surface de section transversale du fil, qui est provoquée par un flux d'air inverse généré au cours d'une étape de réduction de diamètre, est réduite, et une rupture de fil au cours de l'étape de réduction de diamètre est empêchée. Y > −2X + 19 (1)
(JA) 本発明の溶接用フラックス入りシームレスワイヤは、鋼製外皮中にフラックスが充填されてなる溶接用フラックス入りシームレスワイヤであって、ワイヤ全質量あたりの前記フラックス中のFe量が2~15質量%であり、フラックス充填率が10~30質量%であり、ワイヤ全質量あたりの前記フラックス中のFe量(質量%)をXとし、前記フラックス充填率(質量%)をYとしたときに、下記式(1)の関係を満足する。かかる溶接用フラックス入りシームレスワイヤによれば、縮径過程で発生する逆流空気に起因するワイヤ断面積に占めるフラックス断面積のばらつきが抑制され、縮径過程の断線の発生が防止される。 Y>-2X+19 (1)
