Dear all,
I've a question regarding the requirement for inspection of a fillet weld. Materials is A516 gr 70 the type of joint is a lap joint between two plates of thk 6 mm. The plates are used as an internal lining for the bottom of a concrete basin and will be incontact with the fluid contained in the basin (sludge, water and other oils).
The quesion is: which requirements regarding the NDT of this weld should i apply? Visual Inspection of 100% of weld an then? MPI to which extension? Any suggestion regarding standard to apply?
thanks in advance
best regards
Vittorio
