For fully penetrated weld joints, is MT required for non-destructive testing? Is it necessary to apply MT on both the inner and outer sides? Are A, B, and C all needed? Still only the outer surface. Need some advice!
The AB of the main stressed components must be fully welded, and RT inspection shall be carried out; or UT inspection with record-keeping. In very rare special cases, only surface inspection may be sufficient
MT is only used for surface and near-surface inspection, as an auxiliary method for materials with delayed cracks; a basic inspection is still necessary
That’s not the answer to my question. What I want to know is whether, when performing MT testing on ABD welds, testing is done on both sides. Still only the outer surface.
Think about it: if only one side is inspected and it passes, while the other side isn’t checked, and a problem arises in the weld on that other side during use, wouldn’t the inspection personnel be held responsible?
As the owner, it is sufficient to ensure that there are no obvious issues with the equipment and that all completion documents are available； As a supervisor, one can consult the manufacturer about issues that are not understood ； As a manufacturing plant, as long as the flaw detection personnel are bold, surface inspection can be skipped and a report can be issued directly
Also, is this off-topic? Then why did you add a question mark after MT? The question mark comes after the question with two sides
