Conduct weld procedure qualification according to the new standards
Thread Content
I would like to ask the experts: when conducting weld evaluation according to the new NB/T 47014 standard, should the base material standard be based on the old one or the new one? For example, 16MnDR is now included in GB/T 713, but in 47014 it still follows the old standard
When conducting welding procedure qualification, the latest material standards should be followed, even though older standards are still listed in NB/T47014. Therefore, for 16MnDR material, the welding procedure qualification should be carried out in accordance with its latest standard GB/T713. This is done to ensure that the welding quality and safety meet the current requirements for material properties. .
