Are examination records required for threaded joints per B31.3?

It isn't clear if "In-Process Examination" in para. 344.7.1(a) and 344.7.1(g) includes threaded joints. Refer to para. 344.2.2 where specific requirements for visual examination records are listed.
 
A written procedure is required for visual examination. I do not recall any instances of in process examinations related to threaded joints. The ones I recall are as a substitution for radiography on welded joints, brazed joints, bonded joints, and closure joints.

There is not a requirement for a written record, other than that the examiner provide a certification to the owners Inspector that the requied QC has been performed.
 
See SecV Article 9 if VE is required.
