Dear Expert,

As per 650,para 7.2.3.6, Completed weld of stress relieved assemblies shall be examined by visual,as well as by magnetic particle or penetrant methods,after stress relief,before hydro test.

Question:

Is it required for shell to shell weld(butt joint) MT or PT.

If the code calls for mandatory testing, then it must be done, or the unit does not comply.
