NB/T 47014 does not specify a range for the thickness of the surfacing layer in terms of corrosion resistance evaluation
Thread Content
When conducting weld evaluation, the thickness of the base layer of my test piece was 8 mm, and the thickness of the surfacing layer was 4 mm. What is the coverage area of the surfacing layer after successful evaluation, and where can I find the relevant guidelines in standard 47014?
The first of those elements is. . . .
By \"element\", I mean that the thickness of your welded part is less than the thickness that has been deemed acceptable; that’s not what I’m asking about. It has already been found, in paragraph 7.3.2
:Q Does that item refer to the coverage area?
