Chris,
5.22.1.1 Faying Surface. The separation between faying surfaces of plug and slot welds, and of butt joints landing on a backing, shall not exceed 1/16".
The only "intimate contact" I know about has nothing to do with welding. LOL!
Hope that helps,
Regards,
Shane
I don't believe it's ever been "intimate contact". Going back to 75 D1.1 It states:
3.3 Assembly;
"The seperation between faying surfaces of lapjoints and of butt welds landing on a backign shall not
exceed 1/16"
I believe you've gotten this confused with another code. I've seen/heard the terminology used before,
but not in association with D1.1
