Dear Sir
I think your client insist to use 2.5 electrode because of complete penetration and fusion not because of the WPS restriction , correct ?

Dear,
According to QW-404.6, change in diameter of electrode is a non-essential variable(If there is impact test, change in dia greater than 6 mm is supplementary essential according to 404.7).
If no impact test is required, then you can just revise your WPS as per 200.1 (c ).
Thanks & Regards,

Subject: [MW:16785] WPS preparation of 48" API 5L x46 pipe.
Dear all,
I have problem for preparation of WPS for 48" API 5L X 46,12.7mm wt. pipe, the WPS criteria meet as per ASME. We are suggest for E6010-3.2 mm dia electrode for Root pass, but our client can't accept for it.
They have suggest for E6010 - 2.5mm dia electrode.
so please suggest me
