Hello again gentlleman, this is the Data,
Soxket welds with Superduplex 1/2" OD tubing, welded Tig, inspected VT, PT and hydrotested all acceptable per code.
We sampled some of the welds and did destructive testing ( macro, micro, hardness test and feriite content )
on the macro pictures in all of them we have LOF showing at the root, on the cut out pieces you actually can see it with the naked eye.
RT was performed before the destructive testing and the film also shows LOF.
Any comments on this issue will be of great help, previos history , similar cases anything, .. Thanks
