Hi Joe,

First reach for the Caesar Manual and read about the nifty little trunion elbow sif module... I think its in the Tech Guide?

Secondly go to the WRC website and order a copy of bulletin 448 "Evaluation of welded attachments on pipe and elbows"

Or do what most people like to do... ignore the problem and hope it doesn't break! Although I like the applied science answer I sleep better!
