welds are a universal problem in other projects as well. lots of money and effort are expended to assure quality work and prevent failure
had the proper welding procedures been approved in advance and the followed there would have been success
the problem lies with the person doing the welding
where are his certifications?
I would opine that Affirmative Action was the weldor’s certifications.
could have been a she that did the work.
I don’t know but would wager that there is not a welded part on that sub that is not x-rayed, UT and mag particle tested prior to it being approved for use. There should be a paper trail of it being signed off on. Somebody should be in some hot water.
The welders could have been certified, and performing to an approved weld procedure, and still messed up. Mistakes can happen. It’s just that the inspectors should have caught it.
Sophisticated jobs like this have weld maps that are keyed to the x-rays taken. Everything is, or should be traceable. Somebody signed off on this, and that somebody is going away for a long time.
Affirmative action welder.
