Abstract

A submerged arc welding method and more specifically, a multiple electrode welding method is disclosed wherein welding is performed by arranging electrodes in such a manner that the distance becomes at least 300 mm between a first molten pool formed by multilayer welding or by a single or plural electrodes preceding along the weld line and a subsequent molten pool formed by a single subsequent electrode or plural subsequent electrodes, as well as a submerged arc welding method which is characterized in that there is formed a slag having the components listed below on the weld metal formed by an electrode or a preceding electrode forming a preceding layer, and welding is carried out as such, without removing the slag, using an electrode or a subsequent electrode forming a subsequent layer; TiO2: 20-65% by weight (up to 60% by weight, based on the total TiO2 amount, of which may be substituted by ZrO2); CaF2: 9.6-40% by weight, and Al2O3: 10-56% by weight.
