本条例的目的,是规定射线探伤人员必需遵守的技术操作要点,以获得灵敏度符合要求的射线照片。本条例适用于对接的钢件熔焊焊缝,包括环形对按焊缝。制订具体产品射线检验操作规程时,应遵照本条例的规定。 1.表面要求:焊缝需经表面检验合格后才能进行射线检验,其表面不规则程度以不妨碍照相的辨认为度,否则必须事前加以修整。 2.试件标记:每个要求射线照相的试件,必须有表明该工件的钢印(如因故不能打上钢印时,需在报告上说明),焊缝被检验部分的标记(编号和箭头)原则上用钢印,但也可用白漆标出,但必须附有检验部
The purpose of this Ordinance is to set out the technical operations essential to be performed by a radiographer in order to obtain radiographs of satisfactory sensitivity. This Regulation applies to Butt Welds of Welded Steel, Including Round Butt Weld Seams. When formulating the operation rules of ray inspection of specific products, the provisions of these Regulations shall be followed. 1. Surface requirements: the weld seam to be surface tested for ray inspection, the degree of surface irregularity does not prevent the identification of photographic degree, otherwise it must be pre-trimmed. 2. Specimen Marking: Each specimen requiring radiography must have a stamp indicating the workpiece (as indicated on the report if stamping is not possible for some reason), the mark (number and arrow) of the portion of the weld being examined, In principle, the use of steel stamping, but also available white paint marked, but must be attached to the inspection department
