All Quality Certification Authorities that I am aware of, such as AWS, ASME, AISC, ISO, etc. etc. have strict rules concerning the separation of Quality dept personnel and Production dept personnel.
This is to help prevent conflicts of interest.
This may not be the case at your job, but even so you'll probably be put on the spot sooner or later by having to reject work that has been performed by your co-worker buddy, or even your supervisor.
Welcome to the fun world of Inspection!
As far as how to separate the two jobs, I suggest that you get a clear definition of exactly what duties you are expected to perform and make sure that all affected supervisors have received this definition.
Good Luck!

If on the same job, I really don't think you can work as both a welder and a CWI. As I read the "code of ethics", if inspecting, you are responsible to ONE employer, in ONE capacity, on any given job.
Welding on this same job might mean a "conflict of interest", which the "code of ethics" is very much concerned about.
In some of the jobs I have been inspector on, I often have to sign a paper regarding conflict of interest.
All is not lost, however. The code of ethics does allow deviations if ALL concerned parties sign off on a document stating these deviations. If this is the case, I would keep this document in a very safe place.
As a CWI-you must protect your integrity at all times. It is all you have.
You spent much time, effort and money becoming a CWI. Do not waste this effort on a single job. As far as the "code of ethics" go-if doesn't seem right to you or you have questions, it will not, most likely, pass a "code of ethics" review.
Many don't care-but you should!
Hope this helps
Good Luck
