| description | PROBLEM TO BE SOLVED: To provide a flux-cored wire which can provide a weld metal having excellent low-temperature toughness, has a high welding execution efficiency, and enables the omission or simplification of preheating executed for suppressing cold cracks.SOLUTION: This flux-cored wire contains one or two or more kinds of CaF, BaF, SrF, MgF, and LiF. When a total amount of their contents is α, the α is 2.0-7.0% by mass% to the total mass of the flux-cored wire and contains one or two or more kinds of Ti oxide, Si oxide, Mg oxide, Al oxide, Zr oxide and Ca oxide. When a total amount of their contents is , the is 0.2-0.9% by mass% to the total mass of the flux-cored wire. A ratio of the CaFcontent to the α is 0.90 or more, and a ratio of the α to the is 3.0 or more and 15.0 or less.
【課題】優れた低温靭性を有する溶接金属が得られ、かつ溶接施工効率が高く、かつ低温割れ抑制のために実施される予熱を省略、あるいは簡略化できるフラックス入りワイヤを提供する。【解決手段】このフラックス入りワイヤは、ＣａＦ２、ＢａＦ２、ＳｒＦ２、ＭｇＦ２、及びＬｉＦのうちの１種または２種以上が含有され、その含有量の合計をαとしたとき、前記αが前記フラックス入りワイヤの全質量に対する質量％で２．０〜７．０％であり、Ｔｉ酸化物、Ｓｉ酸化物、Ｍｇ酸化物、Ａｌ酸化物、Ｚｒ酸化物、及びＣａ酸化物のうちの１種または２種以上が含有され、その含有量の合計を としたとき、前記 が前記フラックス入りワイヤの全質量に対する質量％で０．２〜０．９％であり、前記αに対する前記ＣａＦ２の含有量の比が０．９０以上であり、前記 に対する前記αの比が３．０以上１５．０以下である。【選択図】なし |
