Zusammenfassung:PURPOSE:To make uniform penetration of electroslag welding of extremely thick steels. CONSTITUTION:Two power feeding nozzles 80 and 90 are inserted into a groove which is surrounded and formed by straps 3 and 4 and base metals 1 and 2, the power feeding nozzles 80 and 90 are oscillated in the same direction in the lined-up direction thereof at the same time and stopped temporarily in the vicinities of a groove end part and the groove central part, the current energy Wm when the power feeding nozzles 80 and 90 are oscillated, the current energy Wh at the time of stopping at the groove end part and the current energy Wc at the time of stopping in the vicinity of the groove central part are regulated to Wc
