Abstract: The present invention provides the following: a covered flux which has a low chromium content and which can improve the fatigue strength of a weld in additional welding; and a covered electrode. The covered flux used for a covered electrode has a composition that contains, relative to the total mass of the covered flux, 35-55 mass % of a metal carbonate (in terms of CO2), 10-30 mass % of a metal fluoride (in terms of F), and 8.5-20 mass % of Mn and/or 7.5-20 mass % of Ni. In addition, the covered electrode is obtained by coating an iron-based core wire with this covered flux.

Abstract: The present invention provides a flux-cored welding wire comprising a shell having a tubular cavity, which accommodates flux. The shell is made of 400 series stainless steels. The deposited metal formed after the welding using the flux-cored welding wire of the present invention has more uniform chemical compositions. Because the loss of chromium during the transition to the deposited metal is less than 0.1%, recourses is saved and welding cost is reduced. The filling ratio of the flux-cored welding wire of the present invention is 5%-25% (preferably 10%-20%). As a result, not only the stability of the compositions in the flux is increased, but also the disadvantages to the manufacture process caused by high filling ratio are avoided. The flux-cored welding wire of the present invention will not be rusty even after it is exposed to the air for a long time.
