hey guys welcome back to world comm so today we have a very special guest in with us today mr.
Adam booth or a-bomb 79 is he's better known from his YouTube and Instagram channels he's come down
to do a little bit of welding with us he was in town anyway checking out the beaches so we
decided to do a little bit of a collaboration so we kind of want to find a rod big enough for a
bomb so that's exactly what we've done we've we have the 3/4 inch core met F 25 electrode we're
gonna use on some 3/4 inch plates we've ran this test before but we want to expand on it
a little bit because everybody in the comments section asked for they wanted to see a cutting
edge so that's exactly what we're gonna do Adams gonna run this rod we're gonna be running about a
thousand amps thanks to ready arc for getting us sorted out with the the DC 1000 as well as
the generator so we're gonna run a thousand amps on a three quarter inch plate once we get
done we'll go ahead and do a cutting edge and check the depth of penetration on this thing
now as we said before this rod is typically used in boundaries so they have the big molds
and casings and the crucibles that you know they get cracked or worn out they actually go in with
this this rod and they weld the the areas that need repair and then they can machine it back
out or just leave it whatever the case may be but that's typically what this raw is used for
it's only good in the flat position so that's why we're going to run and a regular 3/4 inch
butt joint here if you were to try to do this in the horizontal it just wouldn't work there's
puddles way too fluid you kind of see that once you get behind the lens how fluid that puddle is
and you really just have to hold it in place to kind of act like a tripod I'm sure Adam be able
to take care of that for us so I'll give it my best shot I'm actually looking forward to this
because the largest electrode I've ever owned is a 5/32 7018 I've run a lot of 70 24s also so
it might be just like a supersize 70 24 it's very similar to the supersize 70 24 yeah this is really
cool though so I'm I'm looking forward to trying it man let's go ahead get into it alright so in
previously stated we're gonna be running off this DC 1000 here donated or sent to us by Reddy arc so
thank you guys for pulling and pulling the strings and getting this stuff to us we really appreciate
it we're gonna be drawn about 115 amps now we don't have that capacity for three-phase 460
in our building so let's go ahead and check out the power source for the power source
so we're here from the Power Pro 150 this is actually the power source we're going to
use to run the DC 1000 to be able to do the the welding that we're going to do typically you're
going to find these out in the field you can hook up multi banks of welders to these so a
lot of times they'll just have a whole 6-pack or more hooked up to one of these bad boys to
be able to power the entire jobsite today we're just going to use it for one welding machine
[Music]
all right so right now we're hitting just over a thousand have almost 1,100 you're just gonna use
a regular drag technique very similar to a 70 24 you can see it as a super fluid puddle I'm
really interested to see what type of deposition we got on here now it is extremely hot so he's
probably gonna run about half the plate and then we'll stop we'll let it cool down we're
gonna do a cutting edge I want to see what this this penetration profile looks like we have two
five hundred amp rated ground clamps hooked up to this or work these clamps hooked up to the
material because we're running those right off the same machine you just can't run a thousand
amps off one table same thing with the makeshift stinger we got to 500 amp cables run into that
there's almost up to the point but you can see how fluid that puddle is and that's exactly why you're
only able to run this in a flat position you're not getting out of position for this thing anyway
but you wouldn't be able to run like a horizontal T joint with this either because the puddle is
super fluid you'd never be able to maintain that vertical leg on the piece like I said it is a
mechanized process and we're running it manually so we're gonna take that into consideration as far
as well quality one I've done but overall I mean this stuff runs pretty smooth it's very fluid you
can actually see this batter coming off this thing is the size of small cooter marbles this stuff's
pretty intense and like I said the heat coming off it is just extreme we've got three fume extractors
coming on here to pull off the amount of fume that it's generating and it's probably still not
adequate enough once then thanks again to read ER for loaning us this DC 1000 as well as a generator
to power it make sure you guys this is ready art for all your rental needs man I can't wait to dig
into this and see what the penetration profile looks like on this I bet it goes halfway 3/4
through hey that's hot we are sweet that is fill the you feel the UV off that one
I was trying to get a little bit extra rod and I was having too much fun so you came down here to
work on your tan lines at the beach you didn't think you'd be able to do it here in the shop
look the conqueror he's glowing underneath Wow the I could tell when I first started we were
just like blowing through it was there wasn't enough material there at the very end it's all
kind of poured off the end a little bit but as I got into you know it started blowing a pretty
decent puddle there what'd it feel like holding all that it's just it's crazy man like it's it's
a total different feeling to me having a hold of rod like this with you know two arms where
I am that's right it's like holding any good yeah that's what it feels like to hold a mini gun but
that's a little awkward but it's a neat experience it's it's a little bit on your back because you
got a you know where it's positioned that down here you just got to kind of hold it so mm-hmm
it's uh it's interesting experience though now we got to find a chipping hammer big enough to knock
all that slag off we'll get it cleaned up I think we let it cool down just for a little bit we might
even quench it cuz we're not doing a bend test on it yeah but we'll get it cooled down enough
we'll cut you know do a flame cut probably halfway 3/4 away through yeah somewhere in here yeah and
then we'll just well what we'll do is we'll cut that with the oxy fuel clean it up with a couple
different types of grinding discs yeah and just to kind of polish that bring it too closely to
a mirror finish yeah and then we'll hit it with I think we have 5% for your attic acid or ferric
acid and it'll just kind of bring out that weld nugget you'll be able to see the dissimilarities
between the weld nugget and actual the base metal alright cool so we'll be able to see you what kind
of penetration I got exactly that right there I'm thinking it's I mean that's three-quarter inch
plate probably half inch to 3/4 of the way through the plate if not all the way like I mean soon as
you got done you can see the glowing reflection over off the off the concrete yeah so you could
tell I mean the heats definitely getting into it yeah and the whole time you were going to
see you were hitting right around 1,100 amps no kid yeah so it's actually a breeze I've ever run
on anything oh for sure all right we'll go cut it and do it door acid etch on yeah let's get cleaned
up I'm gonna go ahead and chip the flux off of it look at her feet here see what's under the hood I
almost need a pickaxe that's right this would be a good one for me new skill to come for cure we'll
get cleaned up I've never seen to do that before right there it's almost like little pockets you
know I mean that it's kind of like because of how fluid that puddle actually is I think is because
it's it's just so liquid you can't control it was like with seven 1870 24 you got a thicker
slag coverage okay so it's easier to maintain a good clean beat appearance okay oh this stuff I
don't think it really matters when they're welding up the big flag box I don't think they care about
looks as long as it's gonna hold and right and resist so this kind of stuff isn't going to be
out there on a on Instagram for the prettiest will oh no no no these are hashtag real welds there you
go yeah we'll get it all cleaned up quench cut it polish it up check out that depth of penetration
in there that's really what I wanted to see I know we had a lot of comments when we we previously
did this they wanted to see an acid etch on it so feeling we'll give that to the fans all right cool
[Music]
all right so you see when I was cutting there it kind of blew back a little bit we've got
like a little swag partner not slag pocket but like a large porosity pocket right in there so
as I was cutting through it almost snuffed it out so I went ahead and changed direction cut
from the other side right into it and it just kind of released almost like trap gas it was
in there yeah okay so it's a very unique process and like I said I don't know how
much detail they go into to do any post well clean up other than chip the slag out and then
you know throw it back it sort of the slag pot back in there for back into production
but we'll go ahead I want to quench this now and then we'll we'll go ahead and clean it
up and acid etch it and just see how got that check out that nugget see how bad I did no no
so what's your process on what we're gonna do here with your assets so anytime we want to
do a net we just want to bisect the welds cut the material even flame cut it you can put it
in saw doesn't matter as long as you cut it now we're gonna go through a process of cleaning and
prepping it up so I'm gonna take this Victor grain this thing just eats material I'm gonna
clean this up kind of get it down rough get the bulk of the cut striations out of there hit it up
with a regular flapper wheel clean that up and then finally take it down to almost close to a
mere polish once we get to that stage we'll actually be able to use some this 10% ferric
chloride and we'll put some of that on there with q-tips and it'll expose the weld nugget
and you'll be able to see the de similarities between the two metals you'll be able to see
the depth of penetration the width all that good stuff so okay he's got to get it too close to a
mirror finish the closer we get it to a mirror finish the better off the results are gonna be
right okay I was just seeing which one you got here so we got a 60 grit flap disc there and
then this is the one that's got the scotch brite yes guy in this so this one right here you can
actually take this if you're doing detail work you can take it pretty much from weld to paint
in one step so you only need to use that wheel okay and then this one right here it's like I
said just we've beveled tons of plates with it taking backing strips off material I mean
they seem to last a lot longer the great thing about them is as you're grinding when the the
abrasive breaks it breaks into another diamond shape okay so it's just layers and layers of
little diamonds on the on the inside and it just continuously cuts until you completely
wear it out yeah that's cool I've never seen it before it's it's a lot thinner than your typical
bracelet right so it gives you a little bit of flex to it as well yeah alright cool yep I can
see it so not it not as deep as I thought it was gonna be I mean that's still still pretty
impressive cuz it's 3/4 inch plate and yeah just measure from that I can actually see good about
about 3/8 about 3/8 penetration in there so it starts right there falls all the way down
mm-hmm right up into there and you can actually see where the two plates originally put it up
so we got about halfway through about halfway into the plate about there's about 3h yeah we've
got halfway there without any joint preparation whatsoever so it was just a square but place you
get creates depth of fusion depth of penetration that's interesting I'm a little disappointed in
my you know inclusions there the little holidays I think for running a process you know manually
that's meant to be done mechanized mm-hmm that's not bad at all I mean this process isn't meant to
do what we did with it but it's cool to be able to mess around with it I mean how often can you
say I ran three-quarter inch welding rod it's probably gonna be the only time I ever run a
3/4 welding rod because it's not like it's very practical yeah it's not every day we're gonna
get a small repair on the shop you know a bust out the old DC 1000 no we might use a 1/8 70 18
or a 5/32 at the most yeah and then do some basic joint preparation I mean you can no problem doing
a full pen weld on it but I think maybe if you want to try that again you know down the road
you know for you guys maybe maybe try it be joint there yeah see if you can get full penetration on
a 3/4 plate rods probably an inch and a quarter OD with the flux and everything on it so yep friends
stick around inch inch and 1/8 wide opening mm-hmm you get a one inch back wanted to take
backing bar on there but yeah that'd be kind of neat to mess around with that might be something
try later was definitely fun really interested in seeing the acid etch process there - yeah me
appreciate you taking the time out of your day to come down and visit us check out the shop
and burn a little rod with us it's been fun I really have enjoyed coming down and I was
love seeing the shop here and all the awesome equipment that you got and being a burnished
rod I looked whatever you said we might put one of those 3/4 rods in your hand and let you burn
those like I'm in let's do it literally once in a lifetime well twice in a lifetime opportunity
now but yeah I mean it's not something you do every day it's not something you ever see
outside of you know what we typically do on basis so it's cool to you know kind of experience some
of those processes without having to go seek a new career opportunity so it's nice to and then
the exposure and stuff that's pretty cool very cool man I've had a lot of fun today well thanks
for coming out man safe travels on your way back thanks for having me and maybe you can sense some
of those coupons for sure that well test coupons with me and we'll just do another video on that
I'll do some welding on those and ship them down here to you you can test them for me yeah we'll
get them all cut up and tested and all that all right let's let you know how that goes all right
make you watch the video first I will I'll check it out all right alright guys well hope you guys
enjoy the video thanks for watching hopefully that answers a lot of questions that you guys
had about depth of penetration and doing a cutting edge using a thousand amp rod so appreciate you
guys watching thanks for subscribing and until next time make every well better than your last
