After mechanical cleaning ( example wire brushing,grinding,buffing) of part to be tested,is cleaning of part by means of cleaner/remover still necessary?or it can be skipped and apply penetrant already?

Should have tilted the plate to do away with glare and let the viewer see. An intentional crack in the plate would have been good for checking engine heads etc.

make sure cleaner flashes off for correct time, 5 minutes min. old cleaners used to flash much faster. if cleaner remains in crack, inspection is void, if being audited you'll be flagged

@crackersphdinwumbology28316 жыл бұрын
I'm an Air Force NDI technician. It's kind of shocking how similar yet different Method C inspections are in the civilian sector. Only 20 minutes of dwell time only using visible dye penetrant! It makes sense though, given its easier, faster, and it's doubtful you need as much sensitivity.

You should clean the plate in one direction. And also apply penetrant and developer in one direction. It is either horizontally or vertically. Not both direction you can use for perfect results.

You must wipe off pentrant vertically or horizontally only. One direction. And way to much developer on your HAZ.
@robertmertz75448 жыл бұрын
+The3Shogun You are correct for most PT applications regarding cleaning. I disagree about the HAZ. I suppose I could have masked the area of base metal that was not under inspection but the developer spray covers a large area and cleans off very easy. The procedure I was following allows me to wipe in both directions and as indicated I won't have a lot of non-relevant indications that need to be re-tested. Also, the weld and HAZ are evaluated based on VT after PT so I can wipe penetrant out of U/C, etc. and measure for acceptance. Cracks that are very tight would not be wiped away but may be missed by VT. I could have explained why I was cleaning in both directions. Thanks for the feedback.

Given Mahlangu depends where you are and who you are working for. My preference is to leave clean, unless there are any relevant indications. If there is a defect that is Rejectable I mark up and leave so the welder/QC or whoever is the one you are reporting to may see... I have worked places where they are big on us leaving it clean and also have been places where they just go to next job/weld...
