Regarding item 3 in Table 9 of NB/T47014

Thread Content

According to Table 9, item 3 of NB/T47014, for repair welding and patch welding, the thickness T of the base material of the test piece used must be ≥38 mm. If Q345R is used as the evaluation standard, then the minimum thickness of the weldment that applies in this case is 16 mm. If the wall thickness of the equipment in question is 10 mm and this equipment needs to be repaired, what thickness should be used for the test pieces in order to conduct the welding process evaluation? If 38 mm is used, the minimum value of 16 mm will not be sufficient to cover the 10 mm wall thickness of the equipment. On the other hand, using plates with a thickness of 10 mm does not meet the standard requirement that the thickness T of the base material of the test pieces used for repair welding and patch welding must be ≥38 mm. What are your thoughts on this provision in the standard?
