Aren’t you supposed to use 2 90 degree inspections because the direction of the magnetic field you could miss a transverse crack or discontinuity running with magnetic flux lines. Turn yoke 90 degrees and test other direction for defect running vertically in weld . I would run it at 45 degree angle then another 45 so you are not putting probes directly onto weld where you could scratch or damage weld. He could easily miss a tiny transverse crack by not using 90 degree rule. Other than that his powder delivery was perfect along with his use of blowing tool. 👍👍👍
Hi Brad, you are correct regarding 90 degree rule. I did not perform the transverse as this was mainly to demonstrate you can do MT through coatings and the proper technique using the puffer. In general, I do not allow my technicians to do strictly 45/45 as I have seen people miss things due to less magnetic lines of force. I have seen no problems placing the poles directly on the weld or even adjacent as the lines of flux would still work.. Thanks for the comments!
I’m just a student. But getting a megnetic testing procedure booklet, you can buy them. And teach them the laws of physics of magnetic field, and how magnetic particles travel, if you have a crack the megnetic partical will act like a wind and travel downwards or upwards on a defect.
Always fascinates me how I hear of things in my industry and overthink the simplicity only because I haven't seen it. Names can be daunting but are just technical terms.
Thank you so much sir it's good practical sessions but sir one I asking one thing if you got any indication this method that yoke is continue on position and then check any indication have or not means conformation
Hi Daryl,I hardly check this and I should check the comments more often. There are several schools you could attend depending on where you are or find some companies like ours to train you. Hellier in so cal or texas is one. I think there is an online one based in Minnesota if they are still in business. Mike
Michael Foerder thanks alot I'm from trinidad and Tobago I did my level 1&2 penetrant testing also did nace level 1 as well as ultrasonic testing but thanks alot gonna do this with asnt
Daryl, If you're interested, this career field as actually best practiced, and most in depth in the Air Force. AF NDI/Nondestructive Inspections is my current AFSC and I whole heartedly recommend it. You will find far, far higher standards of inspection tools, procedures, and far more impressive equipment.
Very interesting I was “attracted” to this “recording” because it’s in my “field” No seriously we only concentrate on surface braking indications on the whole I don’t try and be flash and point out furring because I don’t have to for most procedures
Why aren't you going in two different directions? Also, 2 inch crack on in the heat affected zone? No sir...that's just holding on the toe of the weld. Try again in the opposite direction...hahaha thanks for the laugh bud
In my opinion, performing MPI with liquid suspension is much easier. This particular way is suitable for hot surfaces. And please, next time put on a respirator.
Worst explaination , you could have specify when to switch on DC power supply and AC power supply , you could have mentioned first we have to demagnetise it then switch to dc/ac current and then perform the experiment
came here to see how a magnetic particle testing works in aircraft, but instead I saw Zeke Yeager teaching this stuff
How lol, how are these yeagerists everywhere
@@davemooreii9943 hahaahh
Came to the comments sections to see if it was just me 😂
that guitar riff at the beginning was sick
With that drum fill brooo
Brief and to the point. Like it.
Very nice information Mr. Mike. Thank You
thanks for the practical knowledge !
Thank you very much!
Good video. Thanks for increasing knowledge.
THank u for such an easy and simpliest explanation once again thank uu
We have some mt inspections at work that are over 2000 shots, including transverse and longitudinal directions. Very tiring.
2000 shots??? Is this for dry or wet Mag?
Thanks! Very simple test.
Do we have to remove the paint before apply MPI method ??
THank u for such an easy and simpliest explanation once again thank uu()
thanks for this testing Knowledge

Excellent an simple
Very Usefull this video 😊
Why you are not doing throughout the weld length ? Skipping some lenghths.
THANKS FOR THE KNOWLEDGE- INTERSTING
Thanks for explanation.
Thank u for ndt through magnetic particle
Hello! Where can I find a sample like this (with a clear indication) to training my students as well?
Thank you for this nice video!

zeke jeager , wat u doin over there?
Thank you so much sir it's good practical sessions but sir one I asking one thing if you got any indication this method that yoke is continue on position and then check any indication have or not means conformation
Thank you for sharing this video
I would not go near an MRI if I were a Magnetic Particle inspector...
For heavy rectangle shaped castings and all (above 1000 kg weight ) which method is suitable or best for crack detection ?
Wet fluorescent
thank you helful.
I have this job. It is interesting to see others in NDI/NDT. ☺
Tara G please let me know where did you learn it
would you suggest this job to an average joe?
by average i mean average in maths 🙏
i hope your account till active 😅
Hemme sceeeneeee🔥
Thanks sir. But sir How many kind off magnetic yoke . Please explain
thanks for the video

very useful
Do you all certifify people ? I'm interested in getting in this line of work

Crackers (PhD in Wumbology) do u need to go thru training as a normal member of the the air force would need to???
I have my test to become a level 1 next week
what is the model no. of probe you are using in this video?
It is a Parker DA-400
i have this job 5 years. But today i have ultrosonic control.
How did you get the promotion

You did not MT in both directions good sir.
Very interesting
I was “attracted” to this “recording” because it’s in my “field”
No seriously we only concentrate on surface braking indications on the whole

This method is wet of dry method?
Hi Manoj, this the dry technique. we typically do very little wet mag as most of our projects are out in the field.
Do you think wet is more effective?
Why aren't you going in two different directions? Also, 2 inch crack on in the heat affected zone? No sir...that's just holding on the toe of the weld. Try again in the opposite direction...hahaha thanks for the laugh bud
should he be breathing that shit dust? thanks either way very interesting!
Thanks Zeke for making me understand Magnetic Particle Testing. I hope Eren understands you too and doesn't destroy the world.
