Abstract
An electro-slag welding method using as a consumable electrode a strip of mild steel and an electric insulating material. The steel strip has a width substantially equal to the thickness of the plate material to be welded. The electric insulating material is composed of a slag-forming agent, a deoxidizing agent and an alloying agent and is disposed between the steel strip and the material to be welded, and also between the strip and shoe, if necessary. The electric insulating material used in the welding method is provided in the form of two plates disposed on opposite sides of the steel strip, or in a hollow rectangular form to enclose the steel strip. The electric insulating material is molded from powdered slag-forming agent, deoxidizing agent and alloying agent with a net of a mild steel material, which is used as core.
