Joint Class I. Joints in this class are double-welded butt joints with complete joint penetration. The root of the first weld is chipped, gouged, or ground to sound metal before making the second weld, and the weld faces are ground or machined flush with the direction of metal removal parallel to the principle stress. Welded joints that are made using backing tape, fusible flux backing material, or a nonfusible backing bar, and are back welded to obtain a completely fused root, shall be qualified in accordance with Section 9, Qualification. Finished joints shall be nondestructively examined according to Section 10, Weld Quality and Inspection, and the results recorded. The fillet weld specimen passes the test if it bends flat upon itself. If the fillet weld fractures, the fractured surface shall show complete fusion to the root of the joint, and exhibit no inclusion or porosity larger than 3/32 in. [2.5 mm] in the greatest dimension to pass the test. The sum of the greatest dimensions of all inclusions and porosity at the fractured surface shall not exceed 3/8 in. [10 mm] in the 6 in. [150 mm] long specimen. Variations in testing procedure, equipment, and acceptance standards from those given in this section may be used upon agreement with the Owner. Such variations include the radiographic examination of fillet welds, T-welds, or corner welds; changes in source-to film distance; unusual geometries; unusual penetrameter application, film type, or densities; and film exposure or development variations. |

焊接接头课程一。这节课中要讲到的接头都是完全焊透的双面焊对接接头。在焊第二道焊缝之前，第一道焊缝的根部会通过切削，或者凿，或者研磨的方式被加工成优质金属，并且，焊缝表面也会沿金属的切除指向主应力方向被研磨或者机加工成平整表面。凡是在焊接过程中使用了垫带、可熔垫材、或者不可熔垫板，并使用了封底焊来得到完全熔合的焊根的这些焊接接头，都应该与《Qualification》中的第9部分要求相一致。焊完的接头都应当按照《焊接质量与检测》的第10部分要求来进行无损检测，并将检测结果记录在案。 角焊缝样本如果可以弯曲平板，那么该样本即通过测试。如果角焊缝断裂，那么断裂表面应该可以看到直达焊根的完全熔合，并且没有最大尺寸大于3/32英寸（2.5mm）的夹杂物或者气孔，这样才算是通过检测。在6英寸（150mm）长的样本中，断裂表面所有夹杂物和气孔的最大尺寸的总和不应超过3/8英寸（10mm）。 本部分所给出的测试过程、装备、和接收标准中的变化可以与物主商量。所谓的变化包括对角焊缝、T型焊缝、或者角接焊缝的射线检测；光源与胶片距离的变化；一些特殊的几何问题；特殊的透度计应用，胶片类型，或者密度；还有胶片曝光和冲洗方式的问题。 |
