This part is Part 1 of GB/T 3323. This part was drafted in accordance with the rules given in GB/T 1.1-2009. This part replaces GB/T 3323-2005 "Radiographic examination of fusion welded joints in metallic materials". Compared with GB/T 3323-2005, the main technical changes are as follows. - MODIFY the scope (see Chapter 1; Chapter 1 of the 2005 edition); - MODIFY the normative references (see Chapter 2; Chapter 2 of the 2005 edition); - MODIFY some term definitions and symbols (see Chapter 3; Chapter 3 of the 2005 edition); - ADD the symbols and abbreviations (see Chapter 4); - MODIFY the minimum image quality requirements (see 6.9; 5.9 of the 2005 edition); - MODIFY the personnel qualifications (see 6.10; 5.10 of the 2005 edition); - MODIFY the ride-on fillet welds into the seated pipe seat welds (see Figure 4, Figure 7, Figure 10, Figure 4, Figure 7, Figure 10 of the 2005 edition); - MODIFY the X-ray machine, which has a tube voltage below 1000 kV (see 7.2.1; 6.2.1 of the 2005 edition); - MODIFY the Appendix A, changing the linear image quality meter into a wire image quality meter; changing the image quality count value into an image quality value (see Appendix A; Appendix A of the 2005 edition); - DELETE Appendix D ~ Appendix E of the 2005 edition. This part uses the redrafting method, to modify and adopt ISO 17636-1.2013 "Non-destructive testing of welds - Radiographic testing - Part 1.X-and gamma- ray techniques with film". Compared with ISO 17636-1.2013, the structure of this part is slightly adjusted, that is, 6.9 will be adjusted to 6.7, the others will be postponed; the order of Appendix A and Appendix B has been adjusted. Compared with ISO 17636-1.2013, the main technical differences and reasons for this part are as follows. - Regarding normative references, this part has made adjustments with technical differences, to adapt to China's technical conditions. The adjustments are reflected in Chapter 2 "Normative references". The specific adjustments are as follows. ● ADD the reference to GB/T 19943, which identically adopts the international standard ISO 5579 (see Chapter 1); ● USE the GB/T 12604.2, which identically adopts the international standard, to replace ISO 5576 (see Chapter 3); ● USE the GB/T 23901.1, which identically adopts the international standard, to replace ISO 19232-1 (see 6.8); ● USE the GB/T 23901.2, which identically adopts the international standard, to replace ISO 19232-2 (see 6.8); ● USE the GB/T 23901.4, which identically adopts the international standard, to replace ISO 19232-4 (see 6.7); ●USE the GB/T 19802, which identically adopts the international standard, to replace ISO 5580 (see 6.9, 7.8, 7.10); ●USE the GB/T 9445, which identically adopts the international standard, to replace ISO 9712 (see 6.10); ●USE the GB/T 19348.1, which modifies and adopts the international standard, to replace ISO 11699-1 (see 7.3, Table 3, Table 4); ●USE the GB/T 25758 (all parts), which identically adopts the international standard, to replace EN 12543.1~ EN 12543.5 (see 7.6); ●USE the GB/T 19348.2 to replace ISO 11699-2 (see 7.9). This part also made the following editorial changes. - DELETE ISO 5579 and ISO 19232-3 from the "Normative references".
