1. 1595 is no longer in effect It is superseeded by D17
2. 2219 is in force... However, welder performance qualifications are per D17. Procedure qualifications are per 2219
If your contract doccuments call out for 1595 I would get a clarification by the EOR to be sure they will accept D17 welder performance quals.
If your contract doccuments call out for 2219 than welder performance qualification testing to D17 is spelled out in the text of that doccument.
The gist is... If you are working to 2219 you need to have and comply with both D17 for welder performance qualification and 2219 for everything else... You need both.
