I used this penatrant on hydraulic oil pressure tank builds for Queensland power station, very effective and a must use to ensure a no leak unit was built , great content love ya work !😀👌
Hey there! I just grab this video to learn some terms of NDT before I'm go to study and pass the exam for certificate. Thanks a bunch! Take it easy buddy.
I was at the edge of my seat waiting to learn how that test works! I'm also thinking "it's got to be difficult to make a bad weld on purpose" after seeing the copper wire it all made sense. Thanks for sharing and as always keep building👍
Thank you for that demonstration as I didn't know what a dye test was. I just watch a video of a sailing vessel that lost their rigging costing them thousands of dollars. A dye penetration test could have exposed the shackle that was about to fail if they had taken the time to do the dye test.
Piece A looks to have some discoloration in the weld beads and also surface deposits that are way different to piece B. Piece A beads look less uniform and more ridged up too. So in my opinion Piece A ang my second choice is Piece B just in case I got it wrong first time!
Hey guys, greetings from Germany. A few points I'd like to add: Spraying the dye penetrant can result in a big mess, especially with windows / doors opened. Depending on the length of the weld I prefer spraying in a "bottle" and using a brush to apply. A thin coating is more than enough. Most penetrants are made for temperatures from 5 to 50°C, the cooler it is, the longer it should sit. From 5°C (20-25 mins) to 50°C (5 mins). Also cracks and other "shit" you want to check for have to be open to the surface, that includes being free from dust and other stuff, therefor it's wise to use the cleaner in 90° directly on the weld, to hopefully clean everything. Will you show magnetic particle testing aswell?
Good video. Just one comment. You shouldn't just throw those testing tools in your tool box. They cost good money and are designed for accuracy so at the very least store them in some sort of protective case so they can do the job properly.
i think its piece b cus i believe the filling was tough to full because of the extra material but at the same time it could be a cus its filled a lot more so it could be both but im going for b
Slag inclusions arent always open to the surface. I dont think I would add that one to the list. Scratches dont count either. Those would be false indications.
In a pinch take apart a Sharpie permanent marker n squeeze the ink tube onto the weld let dry then quickly wipe 1-2 times with acetone rag n it'll highlight the crack.
Interesting you used copper. I use ESAB MiG wire. The ones I use don’t have a copper coating. The data sheet extols that, saying that there’s no copper contamination. But, they have wire with copper coatings. So, what gives?
Mel Gross the copper coating on the wire is so thin it burns off. It’s their to protect the wire from rusting some companies heat treat their solid wire to prevent it from rusting.
Looks like a crack in plate B. This copper probably isn’t solid copper. Probably has 25% tin content or bronze or brass in it which if it does has zinc in it and definently is what will cause a crack
Any idea if this penatrant can be used on hydraulic cylinders? We have a couple manufacturers of cylinders we know are notorious for welds cracking. We can't test them before rebuilding without risking contamination of our test system. This stuff could save us a lot of time if it will still work with hydraulic oil present.
ChrisAWare it should work no problem, just have to make sure you use the cleaner on it first. It’s not an expensive setup. It would be worth a shot if you could avoid having to do repairs if you don’t have to.
This is ambiguous as in my company after red dye,we let it settle for 12 mins & after white we pause for 5 mins... U aaying it 10 & 10... Tho I'd like to mention i m talking about GI & MS pipes not copper ones
Tell us what you think will be shown in the Dye Pen Test Here to win a bucket dipper...
I think we will see a crack in plate b with the test.

As a level 2 NDT Inspector in PT and RT this is a great window for any welder that is interested in the inspection process
If I don’t learn with You (or Bob M.) its because I don’t want. You guys are fenomenal teachers.
Eduardo Rosales A thank you sir. We appreciate the feedback.
Not to be off subject.. but sending prayers from st louis for bob for what ever he is dealing with!

Plate B is the stuck 🐷! Great video Captain Red Beard!
B plate is gonna be the one with the Defect in it 👌 ... thanks for all the great content
Fantastic video, great teachers in this channel. Thank you
A very old timer technique used in Spain was chalk and a non greasy solvent like alcohol. Some used gasoline, but that would leave contaminants
Thanks for your clear explain about DPI and instruments usage.
Thank you for that demonstration as I didn't know what a dye test was. I just watch a video of a sailing vessel that lost their rigging costing them thousands of dollars. A dye penetration test could have exposed the shackle that was about to fail if they had taken the time to do the dye test.
Great video took a lot away from today's episode thank you
Great video. Thanks for sharing. Greetings from Brazil!
"I hate it when people expect results." 😀
Won't effect this old dog but, as always, learned a lot and enjoyed I much.
You're Awesome!!
This is Perfect and informative video!
B I can see undercutd in it.
Good stuff used the die in a pipe shop i worked in.
thanks for your excellent tests
A great demo , but messy and time consuming ! You should do this demo with MPI and see how much faster this can be done !
Piece A looks to have some discoloration in the weld beads and also surface deposits that are way different to piece B. Piece A beads look less uniform and more ridged up too. So in my opinion Piece A ang my second choice is Piece B just in case I got it wrong first time!
I sure miss Bob and would like to see him back
B cracks and craters X-ray would reveal lack of fusion as well most likely visual would reject as well was d17.1 can be very strict on discoloration
Great vid man. im in New Orleans taking my test saturday. what do you suggest i study if i dont cut the mayo?
Good technic. Thank you for the given knowledge.
Great Teacher thank you
Piece A has the copper in it. You can slightly see the coppery color on the surface.
Don't squeeze the Charmin while cleaning.....gives new meaning to the term Red Beard
piece b was my guess and I see some blue coloring in the base metal that gave me a gut feeling that was the bad piece
Wel(d) explained!

Thanks friends.... great stuff
u.s. marine thank you for your service
Can you do a cut and etch, or a bend test on the bad plate? Keen to see what the cooper does to it
Good video. Just one comment. You shouldn't just throw those testing tools in your tool box. They cost good money and are designed for accuracy so at the very least store them in some sort of protective case so they can do the job properly.
Super informative as usual.1 question. Can you use strong backs on all D1.1 tests?
Crack(s) plate B possibly small surface porosity only open to surface.
Per the navspecsea welding code do the copper coating have to be removed from the welding wire to not produce crackes.
How do you check for cracks on things that don't have a backside, or that which has one that you cannot reach?
Funny intro! Nice!
It's time for your safety write up ( no safety glasses in the shop.)
i think its piece b cus i believe the filling was tough to full because of the extra material but at the same time it could be a cus its filled a lot more so it could be both but im going for b
B & that’s a cool test I’ve never seen one done till now thank you 🙏🏽🙌🏽💯
Can you use those strongbacks on tests? I didnt think we could. Im in Ontario
Slag coldlap with some slag entrapment near surface
I wish you showed the MT VT UT RT
Top notch 👍🏻🇺🇸
Liquid Penetrant is used for cracks.
Cracks in plate B, maybe some porosity under the surface
I've had aluminum and steel coffer dams pass 15 psi pressure tests but fail dye pen test 2 days later after the dye sets in😰😰
In my opinion I would say either lack of fusion or porosity
What about mag flux inspection?
On the failed piece.
Good day
Plate B
Idk but I'm guess A, pretty kool tools thanks I'm get me some
PT TEST indication show undercut, cracks, scarchs, cap porosity, salg inclusions
Slag inclusions arent always open to the surface. I dont think I would add that one to the list. Scratches dont count either. Those would be false indications.
usefull!!!
What happened to Bob M. And Mr. TIG ?
Bob is taking some time to deal with some personal matters. Mr TIG hasn't made videos for years.
Hope he gets back soon... you two are great together.... Happy birthday Bob....
B it has at least one crack that I can see.
I would say cracks and porosity
Good
Your "Bevel" (@ 24:10 of the video) gauge measures both Metric & Imperial, not Metric & Standard.
Stanwood Dave I call them “Freedom Units” ... ‘Merica :o)
I use my calibrated eyes 😎👀
In a pinch take apart a Sharpie permanent marker n squeeze the ink tube onto the weld let dry then quickly wipe 1-2 times with acetone rag n it'll highlight the crack.
My guess is piece B
Very nice Vedeo Technical
Piece B you can see the void already
Weld A

Jason Becker I agree with that, and it’s what I’m sure is true. But then, why would they mention copper contamination?
The process is much neater ir you spray the penetrant in a cup and put it on with an acid brush. An aircraft mechanic trick.
Crack hills that was in the '90s it's a whole new game
Its gotta be B I dont trust that two pass cap
Looks like a crack in plate B. This copper probably isn’t solid copper. Probably has 25% tin content or bronze or brass in it which if it does has zinc in it and definently is what will cause a crack
Paused at 1:35, B has the crack, u can c it running down the middle of the 2 beads for a few inches
☺️❤️
Cracking
Cracks in plate with two beads.
It must Be sample B Must!
What happened to Bob? Stop beating around the Bush! Tell the subscribers......
No beating around the bush going on. When we know more, you guys will know more.
B lack of fusion
# 2
Plate "A"
A Looks funny. Lets see if I am right or wrong lol
Wow! Gloves and no glass's Ha! Ha! Ha! just taken notes!!!!!!
I see comment from 3 weeks ago but my guess is B
Cracks in both!! Lol. No I say crack on B..
Good shit what’s up with the boy bob ???

B
you never spray cleaner directly onto the part, cleaner obliterates penetrant you dont want it in any cracks
I guess b
i guess A
Guessing piece a

We all know crack kills hahahaha
A surface crack.
