is Impact testing required? it will effect other parameters, for e.g QW 409.1 (travel speed and amp are higher in case of hot wire)

I have got a PQR qualified for orbital TIG welding (automatic) with cold wire. Does it qualify for orbital TIG welding with hot wire, all other thinks remaining unchanged ? In my opinion yes, but I am not sure. Applicable construction code is ASME. Welding qualifications are per Section IX.
