Really nice video! I've been welding for 50+ years, with a bunch of Certs. Always followed code, and never had a problem with hydrogen embrittlement, but I've seen it. One weld was so bad that it cracked through, and the fitting fell off. Follow codes and stay out of trouble!! I'm glad that people of our age and experience are willing to pass on such valuable information. Keep up the good work, Bob!
Never welded but due to YOU Bob I am now saving up for a ESAB 215Ic multi process machine. Thank you sir for getting me to want to learn a Skill. Everytime I watch your video's I LEARN something! What a awesome skill to learn to weld. My local trade school here I come baby! Thanks Bob!
Bob, I have seen something similar in a video I got from Lincoln Electric. The phenomenon is hard to describe, but when you can see it as you have shown, it is a whole lot easier to understand. Job well done Sir!
Really interesting. I have never welded anything in my life, hoping to get my welder next year to start practicing, and your videos have been really informative.
I tested out for a gas company for a small pipeline. One of the welders knick breaks had columns in it. The inspector called it hydrogen pickup. He said the cause was usually from burning rods to short. Just curious if you have ever heard of this?
There’s some excellent information right there for a lot of you YOUNG-DYI garage race car welders out there. And some of the old hands as well. Keep your welds intact.
Nice !!! I would like to see the result with a 7018 that spent a long time on a shelve out of the box. could that be part of an other video ??? Thanks !!!
Thanks for the video! I remember when I went to do welding certification ( I don't have an actual education on it) and they told about hydrogen leaving the weld. But I did not know it literally bubbles out of it :D
so when you preheat you are eliminating the hydrogen from the steel? thank you. And could you explain what a hydrogen crack is for me and the viewers, thank you again.
Very nice and interesting demonstration, thanks a lot! Cellulose partly consists of hydrogen so it is logic that some will be trapped in the bead. So, even if you do some preheating, you never get rid of all the hydrogen. In contrast to this, 7018 is basically hydrogen-free, it only picks it up from air moisture.
I've been hearing about this all along, this is the first demo, ever! I might have thought it was just a few molecules here and there, it's hard to believe that it's enough to make visible bubbles! I'd like to see this on the hot plate. You hear about baking things to get the hydrogen out. Man, just think of what you must get if you weld something that's damp, or greasy, or painted, the way everyone wants to.
I have always wanted to see this done with different contaminants on the 7018 rod. a couple of drops of sweat, greasy fingerprints and a few rain water drops would be interesting. Mark where the portion of the rod with contaminants ends up in the weld pool and then see if that section looks different under the mineral oil. I speculate that it would not take much to significantly increase the hydrogen content of the weld deposit.
Seen a lot of comments about 7018 setting out it will put off just about the same amount if not more gas when submerged in mineral spirits and if your welding a 36 it'll Bend just like Rod that was in a box
Does the 6010 electrode allow the hydrogen to escape preventing embrittlement? Is the 7018 not allowing the hydrogen to escape or is there not enough hydrogen to bubble?
The latest research out of McGill shows that hydrogen embrittlement is only an issue in steels over 40-43 HRC. However it's going to take decades for the industry to catch up to these findings. It's just now taking roots in the fastener world. The joining world moves even slower.
I would like to see how a good dry LH 7018 rod would compare to a completely wet saturated LH7018 but dried by grounding out to the work till hot and all moisture is boiled out before using it right after doing this. Just like many of use have done in a wet or pouring rain environment in the field. Would it pass a test? Thanks, Great videos. Ed K. Cleve. Oh.
...I've worked as a welder a couple jobs.....had a couple pipeliner guys that worked on Alaska pipe (That stuff was all preheated quite a bit)....they liked to grab a hand full of 6010 and dip it in water.....I don't know if it worked any better....we were doing retro fits in a sugar company...lots of corrosive limestone water in there....mostly just black pipe....stainless was too $$$ to use....pipe got corroded away before the welds could go bad....
seeing alot of new information about cold wire tig welding, does anybody else know about this? And what is the advantage of this then tig welding or mig?
Hey bob, im having some problems with spray arc mig, The first couple beads run perfect. No problems at all, i get about 5-6 beads in and the gun is getting quite hot, eventually the wire burns back and welds the tip making it look like the tip of an ice cream cone. Ive had other people in my shop have the same issue, any idea what problem would be?
I understand the importance of low hydrogen weld processes. Pipe work, and critical situation plate welds seem always to start with 6010, then subsequent passes are done with 7018. Is it 6010's fast freeze characteristics that make it a good choice for closing an open root? Is a perfect weld with just the right amount of back side reinforcement more important? or does the subsequent passes with 7018 remove hydrogen from the 6010 portion? Bill Beauregard
Beauregard Electric The fast freeze properties are what cause the root to fill in nicely. It burns through and welds together, but cools fast enough to not drip, and stay enforced. 7018 is used as the cap because it is a strong connecting rod. Think of the 6010 as a base connection, and the 7018 as a reinforcing connection
This is a great question. I have the same question. If Hydrogen, which is obviously detrimental to the weld, can be eliminated by using a LowHy rod, then why use 6010 at all? Also what is the alternative? Would a tig root pass of 70s-6 have the same Low Hydrogen properties?

It would be interesting to see what a 7018 that has sat out in the shop makes for bubbles vs one right out of the oven.
Iain Portalupi Commented above.
Bob, I have seen something similar in a video I got from Lincoln Electric. The phenomenon is hard to describe, but when you can see it as you have shown, it is a whole lot easier to understand. Job well done Sir!
Interesting video guys well done. Can you guys sometime do a video on mig brazing. seems to be a common practice, but little video content about it.
Really interesting.
I have never welded anything in my life, hoping to get my welder next year to start practicing, and your videos have been really informative.
another good video for knowledge. Keep up the good work Bob.

thats great bob, first time I've ever seen this actually happen!!
Good job mate
Nice !!! I would like to see the result with a 7018 that spent a long time on a shelve out of the box. could that be part of an other video ??? Thanks !!!
toupettt We did that and it will show some hydrogen. Not much but some.
Great Video. Could you please do another with 7018 that has been left out or gotten wet vs properly stored 7018
I love that you said
wanna show you something kinda - kinda trippy
Reminds me of old times....
Thanks for the video! I remember when I went to do welding certification ( I don't have an actual education on it) and they told about hydrogen leaving the weld. But I did not know it literally bubbles out of it :D
is this the way to know the electrode hydrogen diffusible

Very interesting video indeed! I would have loved to see a mig weld sample in there just for conversation sake.
Seen a lot of comments about 7018 setting out it will put off just about the same amount if not more gas when submerged in mineral spirits and if your welding a 36 it'll Bend just like Rod that was in a box
I would like a link that gives us more information.
where did you get your sleeves from mr. moffat
Cool video!
hi bob, why 6010 is recommended for penetration for carbon steel where in fact that is not considered as low hydrogen rod..
Mr. Moffatt, How long will the E6010 rod emit hydrogen after being welded?
Does the 6010 electrode allow the hydrogen to escape preventing embrittlement? Is the 7018 not allowing the hydrogen to escape or is there not enough hydrogen to bubble?
Bryan Smith not enough hydrogen in the 7018
Bryan Smith 7018 are "low hydrogen" rods, so there's not enough to Boulder out.
Great video........ Could you please do a review video on the Everlast 256SI? Thanks!!!
Ken A We don't have one at the moment, but I'll see if we can get one.

Is the hydrogen related to the flux or is it present in mig and tig welds also? By the question you know I am a hobby welder.
Doc Twiggenberry Mig and Tig are both low hydrogen deposits.
what about fluxcore ? Thanks !
toupettt Wire feed and tig processes shouldn't be a problem. We haven't tested them yet but shouldn't be a problem.
Gasless would more than likely show a boil. Gas shielded I would suspect to show little to none. I haven't tested either yet.

You need a white backer plate behind your sign bolted to your table, the letters would be much easier to read

Bacona Boys Check that ground for being hot?
I belive it was warm, but bareable.
Bacona Boys You might have to take the gun apart and check connections.

bdon4445 Yes
sorry wrong number hahaha
Learn something new everyday Bob +weld.com your very thorough and appreciate you passing the torch your one of the greatest on yt
David Hogan Thanks man.We appreciate the support.
lol, nice gag reel
You might add some flash to this demonstration if you could collect and ignite the hydrogen.
vert cool
Hey there gentlemen. Amazing science! One question, can this test be done on a V groove joint once the face and root is ground?
Daniel McConnell I haven't tried it but I will.
