摘要
PURPOSE: A stainless steel including a pitting corrosion resistance improvement method and a welding unit through improvement surface modification is provided to improve pitting corrosion resistance by reducing oxide inclusion and to reduce costs by applying a GTAW welding method of low costs as postprocessing technology. CONSTITUTION: A welding unit is prepared. Harmful inclusion(12) is reduced by remelting(13) a surface of the welding unit in inert gas atmosphere. A step of reducing the inclusion is comprised by a GTAW method.
