Two questions on API 650 criteria

I'm recently having a discussion on a project where we have a disagreement with a 3rd party inspector on two topics:
1. They are of the opinion that it is mandatory under API 650 for WPS qualification that a Charpy V Notch test be carried out, I think it isn't.
2. They are of the opinion that the welders must be qualified using the same WPS that are to be used for production welding, I think this is not so.
Considering the possibility that I might be wrong on both this issues, I would like to know my colleagues thoughts on them,

You are correct on both items. Charpies on a WPS/PQR are only required *IF* the tank will require impact-tested welding. Generally, this is not a 650 requirement.
The welders can be qualified to ANY procedure that you 'own', assuming that the WPQ the welder earns will cover ranges of all the PERFORMANCE Essential Variables that will be needed to weld the tank.

You might firmly suggest to your 3rd-Party Inspector that he/she obtain an API-653 certification. If he/she is certified, then tell them from me that they urgently need to re-read ASME Sect. IX. It sounds like they may be trying to apply a Code from some other disipline; like shipbuilding, perhaps.

Lyft™: Pulsed Eddy Current Reinvented

PEC Reinvented—CUI Programs Redefined Corrosion under insulation (CUI) is possibly the greatest u
nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?

Cygnus 6+ PRO Multi-Mode Ultrasonic Thickness Gauge

The Cygnus 6+ PRO thickness gauge is the most advance gauge within the Cygnus range with key featu
res including: comprehensive data logging; A-scan and B-scan display; manual gain control; Bluetooth connectivity; and much more. With its unique dual display and three measuring modes (Multiple-Echo, Echo-Echo and Single-Echo), this surface thickness gauge offers maximum versatility for inspections.

Surf-X® Array Probe

Introducing the Surf-X family of flexible Eddy Current Array (ECA) probes. Featuring unique multiple
coil sets and proprietary X-PROBE technology, Surf-X array probes can quickly and accurately handle a range of inspection applications, from inspecting corrosion or cracking in pipes, pressure vessels, or tanks, to assessing and sizing cracks in raised welds and friction stir welds.
