Beschreibung
Zusammenfassung:	PURPOSE:To improve the corrosion resistance of a container by controlling the carbon content in an electrode consisting of an austenite stainless steel, etc., to a specified weight % or below, and also controlling the total boron quantity to prescribed ppm and moreover, controlling the 10B in the total B to specified ppm or below. CONSTITUTION:An external magnetic field is formed by providing a solenoid coil against an electrode, and buildup welding is executed under the stirring of a molten pool. In this case, the C content of an electrode for padding consisting of the austenite stainless steel, an Mo-contained and Nb-contained stainless steel or an Ni base alloy, etc., is controlled to
