What's the question?

Can you do it - Yes of course.

Do you need a WP for this - Yes

What's the issue / problem / concern? Please elaborate a little more than one line.

OK, You have a WPS for X 52 and one for X65 Yes?

I'm not sure whether either of those covers X52 to X65, - you really need to ask your welding inspector if this is an essential variable to 1104, but I would submit a new WPS specifically for this joint.

Have a search in the welding forum as well.

I misunderstood your question.

bo7winner,
Do you have a copy of API 1104 ?
Have you ever opened it ?
It took me approx 30 seconds to find the answer for you above.

My online mentor for over 15 years (who is sadly departed) said we are here to help when you have tried everything you can to solve your own problem.
Then you ask for help and we gladly assist.

There is too much ignorance or laziness on this forum at the moment - why bother wasting your time when you can just post a question and let others waste their time.

Upon review of the OP's previous posts, I dont believe he would really care or bother for our opinion. He just seems to post his (vaguely specified) question, seems to accept any answer (regardsless if it's verified to be correct), and then never comes back - not to further discuss, nor to say thanks. These are the kind of users that have made me hesitant of posting lately.
