I assume the support will be attached by means of a fillet weld.
What is the throat size? You may do not need PWHT

Dear Experts,
-- We have the Cladded Pipe of ASTM A335 Gr P11 (9.3 mm to 25 mm) with internally cladded with SS347 (3mm).
We need to weld the Pipe Support with the pipes.
Our pipe support is P11 grade and the WPS is qualified with PWHT @740 for minimum 2 hours.
If we do PWHT is it going to effect the SS cladding? is there any corrosion issue.
We need your kind advice.

Thanks & Regards
