Beschreibung
Zusammenfassung:	The present invention addresses the problem of providing a flux-cored wire that secures weldability at the level that has been demanded in the past while being able to further limit the occurrence of lower temperature cracking by improving resistance to moisture absorption compared to conventional wire. The problem is solved by a flux-cored wire (10) for arc welding in which flux (2) is filled inside a steel hull (1), the flux-cored wire (10) being characterized in that the flux (2) contains 20-50 mass% titanium and titanium oxide calculated as TiO 2 and the moisture adsorption area of the flux-cored wire is 0.020-0.100 m 2 /g.
