Dear Ruban,
Code of construction (like ASME Sec. VIII, I etc.) is tell us to qualified welding procedure as per ASME sec. IX.
So please refer UW-28(c) of ASME Sec. VIII Div. 1.
As I understand, fin is non pressure part & have no-load carrying function and it is performed with automatic welding process so procedure qualifications is not required as per code of construction.
But still you want to check quality of fin to tube weld, you can refer international standards, which ask for pull out test and fusion width measurements test. Also you can refer various standard like GE, Dossan, EIL, IBR etc. for more testing requiment.

During finning, please consider UCS-56 (tables), to waive off PWHT requirement.
QW-263 is for resistance welding processes like spot, seam, projection weld.
Thanks & Regards

--Dear Experts,I have a basic query on welding of finned tubes using high-frequency continuous resistance welding.Design Code of the component: ASME Sec VIII, Div. 1.Which is the applicable clause for qualification using ASME Sec IX?? Is it Table QW-263 ??Kindly provide your feedback if there is any other criteria's or qualification requirements that are to be met.Thanks.Ruban Stanley S
