... with the weld root. Butt-welded joints are more resistant to fatigue-induced damage than socket-welded joints because the annular gap is eliminated. Experience shows the vast majority of socket-welded joints (in excess of 99%) perform reliably, so socket-welded joints will continue to be used at CPSES...
