Re: [MW:13465] Hydro testing failure

Dear Friends,

as we can see, defect is not on the weld metal. this defect(base metal burned) accrued on base metal due to tack weld. it happened when tack weld made on low thickness stainless steel.

Dear friends,

 

During hydro testing of stainless steel, recently 2 tests leak occurred at welded joint area. I verified RT films, PMI reports...etc.Just I want to find root cause.

 

Please advise me that what proactive surveillance need to take of further hydro test failure & how it is happening..?

 

 

 

Thank you & Best Regards,
