What is the intended service of this pipe >>??

Unless you have a backing ring or back gouge and back weld that butt joint, or produce a partial penetration weld, there are no prequalified butt joint details in D1.1

D1.1 has a selection of prequalified joint details that can be used for different conditions.. drawings are right in the book.. You need to get a copy of D1.1.

Can't help if you don't answer questions.

Let's start over.

What is the purpose or intended service of the pipe?

Are you planning to make the weld full penetration from one side with an open root?

What process/es would you be using?
