本文对闸门产品的设计和制造标准中关于对焊缝分类与内部质量无损检测的要求进行分析,提出了如果能将焊缝类别和焊缝形式二者结合起来提出焊缝内部缺陷的探伤要求,会减少设计要求与质量检验的矛盾,降低产品制作成本与施工难度。建议尽快制订重要的T型组合焊缝内部缺陷探伤方法和等级评定标准。 This paper analyzes the requirements of the classification and internal quality non-destructive testing of the weld seams in the design and manufacturing standards of the gate products. It is proposed that if the welding seam types and the weld forms can be combined to provide the flaw detection requirements of the internal defects of the weld, Will reduce the contradiction between design requirements and quality inspection, reduce product production costs and construction difficulty. It is suggested that an important T-type composite weld internal defect flaw detection method and level assessment criteria be developed as soon as possible.
