One test from each longitudinal, circumferential, and nozzle weld is required. 要求每条纵焊缝、环焊缝和接管测试一处。

Hardness results shall not exceed 210 HV10 for P-1 material and 237 HV10 for P-4 material. P-1 和 P-4材料的硬度值分别应不超过210 HV10和237 HV10。

10.3

Procedure qualification for welding materials having Charpy impact values shall require Charpy Vnotch impact tests of the weld metal and heat affected zone. Impact testing shall be performed in accordance with API 620, Appendix Q or API 650, Section 7 whichever is applicable. 具有夏比冲击值的焊接材料的工艺评定要求对焊缝和热影响区进行夏比Ｖ型缺口试验。冲击试验应符合API 620, 附录 Q 或 API 650, 第7节，取适用的那个。

H.

Three tensile test strips 75 mm by 450 mm shall be cut from the test weld. The minimum breaking load of the strips shall be at least 70 percent of the minimum ultimate strength of the unwelded plate. A weld shall indicate at least 95 percent shear fracture.

从试验焊缝上截取３个75 mm × 450 mm的拉伸试样。试样的最小拉断强度至少为未焊板材抗拉极限强度的70％。 焊缝应显示至少95％剪断断口。

I.

Three cross sections of the test plate weldment shall be polished and etched sufficiently to show the weld's penetration into the base material. Full fusion shall exist throughout each cross section. A minimum of 3/32 inch (2.5 mm) penetration into the bottom plate shall exist. 截取焊接试板三个截面抛光，并进行足够腐蚀直至显示焊缝熔入母材。贯穿每个截面的熔合线应存在。底板内的熔深最小为3/32英寸（2.5mm）。

11.0 11.1

Unacceptable discontinuities shall be completely removed by chipping, gouging, grinding, or other methods (for the type of material being repaired) to clean, sound metal, and the excavated area shall be examined by magnetic particle or liquid penetrant methods to assure complete removal of defects.不合格的连续焊应采用铲、凿、磨或其他方法（视材料返修的类型）彻底去除，清理至基本金属；被挖除区域应采用磁粉或液体渗透法检查，以确保彻底将缺陷清除。

11.2

Repairs to correct weld defects shall be made using the same WPS used for the original weld or other previously authorized WPS. 纠正焊缝缺陷的返修应采用与原始焊缝相同的WPS或事先得到认可的其他WPS。

11.3

The repaired areas shall be reexamined using the same examination method and procedure by which the defect was originally detected. 返修区域应采用与初始缺陷检测所用的相同的检测方法和规程重新检测。

WELD REPAIRS 焊缝返修

11.4 Two repair attempts will be allowed on any one defective area. No further attempts to repair shall be carried out without the authorization of Purchaser. 任何有缺陷区域的两次返修是允许的。在没有得到采购方认可之前，超过２次的返修是不允许的。
