According to the international surface prepa-ration standard for welds, preparation grades before paint application are divided into three levels. These grades are described with rough qualitative representations in-stead of with descriptions of surface treat-ment methods or measurable conditions. In this article, coating thickness and the corro-sion resistance and crack tendency of coated films on welds were evaluated for the grind-ing range in five levels from mild to severe....
