How should we understand the phrase NB/T47014-2011 Welding Procedure Qualification for Pressure Equipment?
Thread Content
In NB/T47014-2011 for the welding procedure qualification of pressure equipment, on page P38 under \"6.1.5.5 When a welding procedure that has been deemed qualified for weld specimens is used for fillet welds, there is no limit on the effective range of welding thickness\"； When a welding process that has been found to be satisfactory for evaluating fillet weld specimens is used for fillet welds in non-compressed weldments, there is no limit on the effective range of weldment thickness. ” How should this sentence be understood? Is there no limit on the effective thickness of the workpiece when welding fillet joints? With a qualified process qualification, can fillet welds be covered arbitrarily as long as the material, welding method, and welding materials remain unchanged? Seeking advice from experts; thanks in advance!
I have the same question; have you solved it? If the issue is resolved, could you share it? Thank you!
First, one needs to understand what the technical parameters involved in welding procedure qualification are in order to grasp the true meaning of this statement and thus find the answer; simply asking for the answer does not help one improve.
