What are the advantages and disadvantages of using mechanical equipment inspectors or welding inspectors, instead of certified coating inspectors, to perform coating inspection duties?

     I fully agree with the views expressed by Joel, as the potential advantage can be cost saving, but when it comes to perfection of finishing,  there exists a quality risk. A coating inspector can be trusted to do a better job out of his expertise in surface preparation techniques.

What quality clothing do you get from a tailor compared to someone who just knows how to thread a needle between two pieces of cloth? Basically, both have the idea of sewing but who will provide a quality job?

From JOEL GINIES of Beckers-Group on August 14, 2012:
     I don't see any real advantage on using mechanical equipment inspectors or welding inspectors to perform coating inspection, apart  maybe from trying to save money by using one inspector for all. You might end up being lucky and getting an inspector who is experienced with coating but you would also take a big risk. Coating defects can be invisible to untrained eye, and only someone experience enough in coatings could truly assess whether a defect can be repaired or if the job need redoing from scratch.

From William Pybus of Me-Myself-I on August 27, 2012:
     Unless the mechanical or welding inspector is cross-trained in the coating inspection discipline (SSPC or NACE), the question is not relevant. Inspection training in one discipline does not automatically provide knowledge or expertise in others. This question reminds me of a statement made long ago on my first QC Nuclear Coatings Project "It's just paint" by someone complaining about scheduling delays due to rework activities. That sentiment is always in full force until there is a problem and then the finger pointing starts as to who is responsible and who is paying for any rework.
