Re: [MW:29364] WELDING DEFECT AT ROOT

kannayeram gnanapandithan  is correct. To confirm it, make a 'MOCK UP' with some coupons and have the welder 'suck back' or in other words provide

selected concavity, selected no concavity, excessive penetration etc. Also have the welder provide an area with excessive root concavity and then weld a higher weld 'cap'  at that area on the O.D. RT the weld mock ups and review the film to show 

how this higher weld 'crown' will mask the root concavity on the RT film.

It is root cavity / suck back. Due to higher reinforcement on faceside u may not get much deffirence

Gents, 

I am getting the attached image in boroscope inspection at root. But RT not showing any density variation or undercut. Please give your comment on it.
