The problem with the piping is not a bad weld, the problem is that the joint was welded at all.
There were defects in the parts in question, and the manufacturer attempted an unauthorized weld repair....and then failed to disclose this fact.
The unauthorized welds were found in a subsequent inspection, after the parts were installed in the plant. The manufacturer certified the parts before delivery...like many parts in military procurement, this is how it works. Critical parts do undergo extra scrutiny.
I can’t say why the defects weren’t found before the parts were installed in the plant...but it looks like someone, or several someones, may be going to prison over this.

It was a Mig 25, flown by Viktor Belenko.
You are not allowed to ask that.
That would be racissss, and islamo-whatever it is.
I got this far before somebody read my mind.
Its an age-old problem: “For want of a nail, a shoe was lost...”
I would think something like this would be TIG welded.
Send in the union crew that did it wrong the first time, and make them stay until the repair is done. That might discourage shoddy work in the future. And it might encourage the crew to work as quickly as possible.
As an alternative, charge the responsible parties with treason, and execute them in front of their co-workers.
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.
My memory agrees with yours on this issue.
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.
check the citizenship of the contractors and their welders
I remember that, but there was a follow-up a couple of years later. Later they put the plane in a wind tunnel and found that the bolt heads were where there was no drag, so there was no problem having bolt heads in those locations. As such, it was an elegant solution to keeping costs down with no loss of performance.
I had the opportunity to talk to a aeronautic engineer who was very well versed on the tests they did. He thought that the plane was engineered to work despite quality control issues. Which in his opinion was quite a feat unto itself.
2 BILLION dollar project and the lowest dollar and skill workers got the job? WTF!
As a taxpayer, we should be refunded fully for the bad work that was done on this sub
No excuse in this
Competent welders should have been found for this job
interesting....as I understand, the Soviet military was designed for 10 day war +/- hence ships, tanks, truck and aircraft engines were capable full power for 10 days and then died
strange that bad welds were in the area of the Nuclear power plant....doesn’t that detail ring a few alarms??
Evidently, I’ve seen it twice...
