A CWI cannot sign off on a PT report with the CWI cert alone, however a CWI may have multiple other certifications that qualify them for doing so. ASME XI VT1 as of 98 accepts a CWI for VT 1. (Div 1, article VI-4110) for confusions sake, VT 1, 2, and 3 in the nuclear world are surface, leak, and pumps and valves respectively. Not as in Level 1,2, and 3 TC-1A. I realize you know that jon, the post was meant for some level of clarification for others.
