Abstract：The problems of identification and judgment for the surface roughness of the ship plate were analyzed, and combined with many years of experience, a series of work was carried out to improve the accuracy of identification and judgment for the surface roughness. Through comparing nearly a thousand pieces of plate before and after shot blasting, the color and scratch of the steel plate surface were identified. And on the condition of ensuring the effective identification, it can promote the transition of the inspection standard from the product standard to the customer standard. According to the differences of the defect depths, the use locations, and the distribution areas, combing the different quality requirements of the different customers, the accurate identification of steel plate were obtained, which can ensure the accuracy and effectiveness of the identification and judgment of the steel plate, reduce the economic losses, and enhance the competitiveness of the product market.
