摘要： A method of removing surface defects from the surface of a steel product, such as a slab designed for rolling, wherein the defects are melted by an arc generated by an arc welding apparatus having a non-consumable electrode, a guide nozzle about the electrode to maintain an inert gas atmosphere immediately thereabout, and a shield nozzle about the guide nozzle to inject a mainly carbon dioxide gas therefrom, and a deoxidizer is applied to the molten pool formed in the welding operation so as to cover the surface thereof with a slag formed by the deoxidizer which is oxidized.

摘要： An arc welding apparatus and method is described which includes a guide nozzle surrounding a non-consumable electrode and a shielding nozzle disposed outside the guide nozzle so as to feed a protecting inert gas about the electrode from a position within the guide nozzle and to feed a shielding carbon dioxide gas or a mixture of carbon dioxide gas and oxygen or other inert gas from a position within the shielding nozzle, whereby the electrode is protected by means of the guide nozzle and the protecting gas supplied therethrough and the outer portion of the arc is cooled to restrict the radial extent thereof by the shielding gas, while a deoxidizing reaction with the melted metal may be performed by means of the carbon dioxide gas and a deoxidizing agent within a welding rod when the latter is employed between the electrode and a base metal, or in the vicinity of the welding arc.
