Weld overlay performance qualification for fillets 1

[Zee S]

Hey guys..
Construction code.. ASME BPVC SEC VIII DIV1 & 2
Qualification code.. ASME BPVC SEC IX

Quick question, if a welder is qualified for corrosion resistant overlay, would he be qualified for all fillet welds as well?

Nope.

Have a read of QW-381.2(b)

The only possibility I see is if the welder was qualified per QW-381.4

The devil is in the details; she also wears prada.

Nope, He is only qualified to CRO.

He can perform fillet welds for parts that are not subject to loads.
Example: support for nameplate.

When the WPS does not specify any chemical composition for overlay, the welder for such overlay can be qualified in a groove weld performance qualification. If your welder qualified for CRO through this route, he can make fillets too. Otherwise, if he qualified on a cladding coupon, he can make only claddings; he cannot make any fillets.
