47014 Determination of the number of mechanical property specimens
Thread Content
According to NB/47014, for the tensile, bending, and impact tests of different welding methods, should the number of test specimens be determined by multiplying the number of specified specimens by the number of welding methods?
Yes, according to standard NB/47014, the number of tensile, bending, and impact specimens required for different welding methods is determined by the number of types of welding methods used; in other words, a complete set of mechanical property tests must be conducted for each welding method separately. Therefore, the total number of specimens should be the specified number of specimens multiplied by the number of welding methods. This ensures that the weld joints produced by each welding method meet the corresponding mechanical property requirements. .
