this is so much easier to understand then my teachers explains it in front of 30 students, so thank you for this amazing video, I will definitely recommend this to the other students.
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.
Can you provide with the product name and specifications of the red spray dye and cleaning sprays you used? also can this be used to test for solders on PC boards
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
+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.
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.
Hector Paniagua This is Type 2 (visible ) Method c ( solvent removeable ) Form e ( nonaqueous type 2 visible dye solvent based ) Class 2 solvent ( non-halogenated )
Great video! My teacher played this during class and me and my friends laughed at this because you made it look like a Porn video.. I mean the way you were breathing and cleaning 🤣🤣
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...
i wanna learn the liquid penetrant teasting cuz im a radio log i wanna some info about that and i wish if someone contac me for ask him meny thing about liquid and magnet
Well explained, But as per standard practice while applying , cleaning pentetrant from the surface we should not wipe or clean bi-directionally. It shall be cleaned only in one direction, the same is applicable while applying penetrant. Hope i am correct. Regards Dwarakanathan ASNT LEVEL III
Hello! Thanks for useful video! I have the only one question...Why don't you use a respirator? These sprays are extremely harmful for your health, especially for lungs.
for post cleaning you must clean the surface, from first point to 2nd point you can't clean first to 2nd and again 2nd to 1st. you can clean any of one way 1st to 2nd or 2nd to 1st jv071
If provide more close-up pictures for all indications on the second test plate, it will be great.
Thank you. This video is very helpful. We didn`t know before watching this video how to use liquids.
thanks man you did a great job explaining, i am gonna show this to my student for easy understanding
Great demonstration Robert. Mike told me the story behind the test plate. Sneaky!

thanks am actually writing an end of term essay on this, cleared alot of things up thanks.
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.
How to find out the length of a circular defect whose end is loose? as in not connected?
Excellent Video! Thanks!
Me studying, getting asmr vibes from this lmao
Lol same bro
If you spray a paint brush with penetrate and brush weld, will that decrease results or is that ok?
very clear. well-done. thank you
Great Jog Robert! Haven't seen you since the New Bay Bridge Project.
Really good explanation thx
You are an absolutely legend, I hope you know that pal
Why we are not use to cleaner direct sprey in welding .
Close up of defects?
A close up of the plate with the defects so we could actually see what they look like would have been helpful.
+Jjj Sss Agree
Good demonstration but please get the camera closer to show the details. Thank you for posting this!
can this method be used in pipes
great job, we were taught to spray the developer away from the metal first to make sure it's fully agitated tho?
+Planet Beat Mobb Yes you are right. it ensures the uniform spray of developer.
Very informative, Thank you.
Can you provide with the product name and specifications of the red spray dye and cleaning sprays you used? also can this be used to test for solders on PC boards
+Dishita PUROHIT I would recommend using RT for PC boards.
removing pen
etrant is only in one direction ... To and fro is not allowed
Very Nice, Well Done !
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
Why u did to and fro motion which doing solvent removal? It's clearly written in ASME BPVC SEC 5 ARTICLE 6
It was nice illustration of the whole process. Can u tell which cleaner, dye & developer you used here?
Pmet is one the oldest and leading companies.
Different products available as per different sizes of cracks
Thanks for fine explaination.
Sir penetrant cleaning need to do in one direction , am i right ?
You must wipe off pentrant vertically or horizontally only. One direction. And way to much developer on your 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.

Hi..
I have a doubt.
Is there any need to do penetrate test on a complete machining part ?
That was only 10 min of dwell time.
superb video
Nice video moderately informal though....

ya mam absoultly write ...he is not correct because of pentrates also pick out in defects
ya mam absoultly write ...he is not correct because of pentrates also pick out in defects
can you specify where does it say so? in which standard or norm (what page)?
thanks very helpful.
Hi sir
good morning
I'm from india
i finished NDT Level 2
i need a job
did any vacancy is in your factor
This is definitely Walter white Heisenberg
Why cleaning zig-zag.,? Clean from one side.
great job
What method is this
Hector Paniagua This is Type 2 (visible ) Method c ( solvent removeable ) Form e ( nonaqueous type 2 visible dye solvent based ) Class 2 solvent ( non-halogenated )

You are correct
It's cleaning process is not accepted
Tq sir
Camera guy afraid to get close. Otherwise good info
I didn't like it cause a indication in the plate will be better explanation.
Keep doing
Will the fluorescent non-aqueous developer produce better results in evaluating the defects than the visible non-aqueous developer?
Wrong apply method
Well Explained. Thank you sir, please can u list some examples of the liquid penetrant commonly used
Very interesting and well explained. Thank you sir

Hello Guy let mark your Friend too
Watching this just for exam purposes 😑😑😑

hi am NDE man from middle east :))
Goog
your camera man/women is not so very good..
Post cleaning is not proper Way..
Somnath Ghosh why?
for post cleaning you must clean the surface, from first point to 2nd point you can't clean first to 2nd and again 2nd to 1st. you can clean any of one way 1st to 2nd or 2nd to 1st jv071
Somnath Ghosh Post cleaning after the penetrant is applied? What do you mean by 1st to 2nd?
***** 1st point to 2nd point. What Somnath state is that one should clean in the same direction, always right to left (for example)
yaa you are right
