In this episode we are going over some of the common mistakes made in flux core welding overhead with gas. Many people don't believe this is a process that can be done, but let us assure you...It can be and is every day in structural welding.

Still can't believe this type of education -tutoring is for free for us to watch .Thank you Bob
Bob Moffat has such a calm way of explaining and teaching. Such a great instructor.
💯
Absolutely!
I was taught 3/4" total stick out. If you can get 1/4" inside the nozzel then another 1/4" outside the nozzel and 1/4" spray you're usually wetting in pretty smooth.
That how Ive always felt
I got another fluxcore request. Here in Southern California Lincoln NR232 0.072" is the standard for wire welding structural steel in the field. There isn't much on youtube for it, so it would be awesome if you made some videos on doing a 3G test coupon and some multipass fillets.
I would also be interested to see that, E71T-8 wires have a reputation as being more difficult to run, but being a self shielded flux core wire with ductility and CVN values equal to a 7018H4, it is a very attractive option especially in seismic areas.
Not sure why theres even videos on .045 dual shield flux core. I'm no weld professor although i feel as if its one of the easiest mig processes available. I've left the same comment/question you have here on many of the videos here. My current job requires 1/6" wire, not much of a difference than what youre running.
@@robroy5729 1/6" wire??
@@user-mt9tn1ni4g 1/16" ****
Thats some dang stout wire!
Thanks Bob good lesson....Happy New Year to you and thanks for all the great welding lessons in 2018.
Good coaching learned quite a bit on his Mig running.
Great instruction Bob. I love Fluxcore. It is 65 % of my welding days mixed in with Aluminum MIG and Aluminum TIG and Stainless Fluxcore and Stainless TIG. It's funny though...I am right handed-but I DON'T weld from left to right. The guys at work laugh at me, can't figure it out how I weld backwards. And yes you have to drag Fluxcore. They blame it on me being a woman. Oh well. Please keep the videos coming!!!
Im the same, i push from right to left, only reason I push the .045 is that it provides more preheat, lights up the path im welding and offers more penetration than drag. Thats just me.
Great Video learned a lot it was nice watching you teach him more helps learning easier you all da mans 👊🏻🙏
I used to weld overhead at 29v 350wire speed, used to think it was good, til I noticed my arms became super sore after continuously doing with it those perimeters. I weld at 32v and 400 wire speed now, im having my arms up for lesser time, and it’s way less strain on my arms.
Happy New Year 2019! Thanks for the great content!
Happy new year Mr. Bob. And everyone else !!
30 years in repair weld shop business but still pick up some good points from you Bob. Think we could have some good conversation
Love this style of video! Learnt so much more.
How bout some footage on what causes worm holes all around with gmaw to any other mig process
It all depends on the type of Steel you're using and they never show a preheating process which is pretty much crucial any kind of oil paint or Mill scale can affect that type of results mild preheating eliminate a lot of that usually it's about 300 degrees you will see the steel sweating just an observation and an opinion
@@user-mt9tn1ni4g I agree...weld prep. Is the first step in making a quality weld.
"Get comfy there"....#1 rule of welding period.
Great review & techniques!
Was wondering if you could show some gas welding we gas weld anything under 2" pipe
Get stuff and its a so funny its a great to both and how funny your are together it brings some different kind of fun to welding !!
He was exactly right that he did trap slag 7:09 7:01
Nice brother!!
Can you well uphill with flux core ???
thanks for the demonstration
The ending 😆
Bob what would you run 232 4G position at
Who makes the wire ESAB?
First question from the professor do we push or pull the kid says we drag LOL
Fcaw, not gmaw?
Whip it good..🎵... I said whip it
My employer encourages me to do my overhead FCAW with a slight push angle.... what do you guys think of that?
Great teacher! Student needs to listen more and talk less. No offense, as I'm learning as well, but when they say don't change weld angle you don't say it's hard you ask for suggestions how to brave hands so that you CAN keep the same drag angle 😉
Does "The Cub" have a name. Just saying.
yaya. It is Mann Cub,.. Duh!
or furry young animal that walks like bipod, but i am going to keep saying the short ver.
No I mean a REAL name. Like Joe or Fred etc. It might be nice to refer to him by his real name. Unless he wants rename anonymous.
that is his name.. atleast til one better suited comes along. Prediction?
this is a perfect example of constructive criticism, i can see why you are a teacher bob, good pointers as well keep up the good work sir
Seriously, Bob teaches incredibly well. Those two make a really good team on video.
Let's see some NR232 or 232 self shielded FCAW.
Cub says the coupin cooler rolls real nice. Translation: "We had riding coupin cooler races at lunch today!"
😆
looks to me like... if he stood to the right, in front of the weld, his gun angle would improve. The way he is standing now, he has to reach to finish the weld. Reaching to finish a weld almost always changes the gun angle. But, even so, it turned out pretty good.
I always start uncomfortable, work my way to being comfortable, then keep going until it effects my weld
I've said over and over and over to every person I've taught to weld..... Get Comfortable! Use anything at all to find that comfort and do that 'Dry Run' to make sure that comfort is there from start to finish. And as well, exactly what was said here about keeping those angles consistent. Great videos. I'm really into them and even had a dream last night on welding a manhole on a big leach tank on a gold mine. What a sad narrow life I live eh? :)
Duel shield Flux core with c25 can be pushed or pulled @ 5-10°
In addition to the outstanding content, you GOTTA LOVE THE OUT-TAKES!
Your an amazing teacher bob you remind me of my welding instructor I had patient and hands on not everyone can teach takes a very wise person
The first time I tried flux core over head I couldn’t believe how easy it was compared to doing stick over head for your first time! If your machine is set up properly and you hold the right angle pretty much anyone can make their overhead flux core look flat!
If u can stick weld u can flux core. Harder feeding rod and angle then just gun angle
Yeah okay
I use the hobart arc 71 0.45 great wire to been doing 5/8 steel no problem
the Cub ,,, he is coming around , Happy New Year to all there,,,
He's not half bad!
Mancub you're one lucky guy I to have Bob teaching you welding!!
Thanks for the tips , got a 4f test tomorrow . Cheers Bob
Nice closeup of weld puddle! Happy New Year
First question do we push or pull? 1:18.. Cub.... you drag...
I enjoy these videos since it's been almost a decade since I was in college for welding. These are great refreshers.
Oerlikon fluxofil 14hd is what we use to build warships. Not all fluxcores are equal and this stuff for regular temper is a stand out.
Great format, please make more like this. Just keep the stereo feeds on the correct sides or was that on purpose, ( I can picture a sly grin as you hit the upload button and think of the headphone users)?
Where'd Jr. get those spiffy space gloves? Good video and nice weld btw
What a couple of Legends, Makes you damn proud to be in the Industry.
“Old head” ‘this wire is very forgiving and nice to run’
“Knucklehead student” ‘yea! It is real nice to run’ 🤪🥴🤪🥴
“Me” ‘right dude👍🏻 I’m sure you kno what your talking about an kno what wire runs nice and what wire dosnt run good’ 😂😂😂😆😆🤙🏻🤙🏻🤦🏻
. Thanks for taking the time, for the few of us who actually use this as a learning tool. You are much appreciated!
Do a video on metallurgy like the iron carbon phase diagram explain how it works heat treating terms like austenite martensite ferrite bainite pearlite critical temperature of the iron carbon allotrope. I think that would be pretty interesting. Heat affected zone and how that affects the parent material. Tempering annealing normalizing quenching
Bob's a welding instructor, not a welding Inspector. I don't agree with his info, but 85-90% is accurate. The young Hispanic guy (tutor) in this series..... now when he speaks, be sure to listen because he knows his stuff👌
Can you weld flux core up hill
Only reason I subbed so long ago was because of Bob. The way he teaches and explains things makes it easier for me to understand. Thanks Bob. I never see him on here anymore which is sad :(
I push flux core all the time, never had a problem
Overhead welding is definitely something I need to work on this winter. I really need to get my everlast welder out and practice.
At work we run Select Arc 727 1.6mm wire..28.8 volts and 300 to 310 ipm and that's with straight co2.. Your right very forgiving wire and versatile as heck.. Heavy equipment mfg co..
Anyone know if you can run dual shied using 90/10 blend instead of 75/25 ? That's all I keep around because I do a lot of spray arc solid mig and really don't want to have yet another bottle of gas to inventory. Thanks and happy 2019 to all.
Ok, there are many types of gas shielded flux core electrodes, but presumably you are talking about E71T-1, which is the most common and I believe what is being used in this video (Select Arc 720?). You can buy E71T-1 that is designed to run on mixed gas, CO2, or both. Most E71T-1 wires are designated as being acceptable to run on both, and this designated as E71T-1C/M C=100% CO2 & M= mixed gas specified by the manufacturer, usually C25. The as welded material properties of the electrode will be listed for both 100% CO2 and mix 75-25. Any mix between C25 and 100% CO2is acceptable.
Garry Gaudin ... Thank you so much for responding kind sir! I used to run 75/25 .045 wire consistently for earthmoving repair and love it. I wasn't sure if you would reach a point of argon saturation at 90%. Afraid of it being detrimental to weld characteristics some how. Again, big thank you! This is what's great about this forum. Sharing information.
There's a Lincoln product that made to run on 20% down to 5% co2 I can't think of the name/number but once I'm out of what I have I'm gona try that since I have a 330 90/10 and a smaller c25
80% Argon is considered the maximum amount that can be used with dual shield wire.
Best tip for 3F is first run slow, second run fast and third run intermediate. Practice and only adjust your setting in small increments
Nice looking welds, but I wish your video editor would overlay metric,,,,,, by the time I've visualised 5/8th's 🤣🤣🤣 happy new year weld.com
ifell3 Yes, I agree that you need to include the metric sizes of every dimension given. Remember that the show goes out on the WWW and the vast majority of people around the world use the metric system.
It's decimal so there is no need for fractions.
1/2” 13mm
9/16 14mm
5/8” 15mm
Quick rounded conversions. Just like pulling wrenches.
measurements are just numbers either way
Ok chaps, cheers for taking me so seriously, I can work it out but just not fluent in conversions aha
Instructor I had when I was testing for nuclear say you are either a welder or a grinder. I HATE GRINDING. People I work with say I put down pretty beads I tell them that's how I learned
Dude you're criticizing his weld, but your welds look exactly the same. Notice I didn't say "good/bad" for the weld quality. You talk about an "arc" in his bead; but you know your welds on this channel are this same quality as what you criticize.
Flux core runs nice
I work at a quarry so some of the seam repairs on buckets and beds have dirt built up behind the seam which makes it tricky to weld.
Things are going smooth until a dirt pocket deep in the seam blows the weld out.
I do repairs on cracked weld seams and worn down seams.
Big buckets like 10-12 ft wide and 6-7 ft tall or so
One of these welding channels needs to be the first to do a 1in 4G/4F plate lol why are you all scared of the 1 inch? lol In the real world with structural dual shield welding it's not going to be on thinner gauge material. Every situation ive been in that required dual shield was for a minimum of 1/2" and if we did say stuff that was 3/8" or so we'd use smaller diameter wire but you should be the first to weld up a 1 inch since you need higher settings for thicker material.
Love the videos. But I'm having a bit of a distraction. It may be my phone but I hear the left/right audio flipped. When the person on the right talks, I hear it on the left and vice versa
I don't understand how most videos on YT show people welding at 180+ WFS and over 21 Volts. I've tried that at school and it wants to shoot right through the metal or else the plate is glowing red by the end ready to melt. Definitely wanna get to the level where those settings are no biggie lol
Thanks for the session - excellent instruction and with such great video, was able to see very well what was taking place. Have a great new year.
Best tip for 3F is first run slow, second run faster , third run intermediate
Lol..the bloopers!! But thanks very much needed pointers at my current job
Ay yo that is the best welds and information thanks and keep uploading
Thnx for the helpful video guys, from Perth Australia
I love running .035/.045 flux core. And I have run a lot bigger, which is a 'real bear'. Super hot and hard to control. (You need to wear double gloves.)
LOL I feel your pain Gramps I've been running 3/32 311 ni for 20 years and a bunch of other wires before that welding for 35 years in the field structural in all types of conditions when you know what you're doing after a while sometimes you drop your gloves sometimes your glove get soaking wet in the rain you can weld without gloves LOL but don't try this at home
I wish it looked like their camera shots inside my hood. I can’t see shit under there and I’ve tried changing shades and everything.
Damn I think every welder would have loved too have been you're student Bob the man the legend the myth lol 😂
Bob is such a kool, helpful, and humble guy. Cheers to you sir! 🍻
Just wanted to throw this in there about the "piping porosity". Piping porosity as defined by D1.1, for example, is a pore that extends down into the weld metal for a distance greater than the diameter. You will sometimes find this type of porosity at the end of the "worm tracks" but the "tracks" by themselves are not addressed by D1.1. A great video.
I can't understand why he push instead of drag that last run. Help!
You will ruin a $60 shirt like right now, with that overhead stuff
At 1:55, that angle is called the ”Work Angle". The other, travel angle.
Thanks for the nice video.
Happy new year to the Weld.com staff and all viewers.
Why does Bob remind me of Hank Hill?
Go and checkout Thunderhead289..😉
My xray yesterday says ain't nothing wrong with pushing if your hot
I thought flux is only supposed to be pushed , not dragged
How do you do it when you have to overhead weld when it's flat?
I like my hair how I do my welds. Undercut 🤣
Happy new Year guys.
I really appreciate the knowledge you share right here.
Next lets see a tig welding video like this! Keep up the good work!
Bob is the man!
new years eve, and im watching these guys...
kandh555 Sure beats watching the usual NYE crap.
BTW where in the world are you? It's 4 pm New Years Day here in Melbourne Australia and I posted this 1 hour after you. Happy New Year to you and your family. Mark
Wow did you say 26.4 volts with 450 wire speed? What is there WPS settings for this? We have been running ours at 24v and around 350 wire speed I'm cutting about to do my AWS 1" Grove with having 1/4 Gap 35 degree bevel... Struggling ☹️ I'm older so eyesight is an issue in working on. I kept blowing through the backing plate as I changed angle half way through and went slower. Recently was shown how to hold whip upside down which greatly helped. I'm curious to try your settings and see if that helps. I try not to change wire speed from various positions as you can changed it basically by house closed or short your wire is ... Closer should mean faster contact.... Great video.... I'll be watching more.
26.5 volts how many ipm sir?
What are the POWER requirements for running Dual Shield Flux Core wires? I have an Everlast i230 PowerMig and it may not have the oompf needed to run Dual Shield... is this really an issue or do I need to get a higher powered machine? This would be a good subject to cover sometime.
man I should show you some of the stuff I do at work.. 3/4 fillet bead (12 passes) in flat position, and 1/2 fillet bead (6 passes) in ALL positions.. 71-xm .052 wire from esab. actually works out well, just doesn't look like it til you complete that last pass!
I would love to have one of those jigs you are using the practice different positions of weld where can I get one
There are several you can buy or you can fabricate one to your liking.
I spent a moon or two running .045 flux core overhead on structural, but I think it was straight CO2. Bossman wanted us to weld over 1/8" + thick paint. While he was grinding, chipping, and re-welding - we were moving on to the next piece because we used wire wheels. But of course that was just a "waste of time" and "making a mess" :D
How can he see where he is going welding that way
Interesting, I don't know anyone that changing setting for overhead. I've always just welded all positions the same. The setting only change according to weld size and metal thickness.
Hey Cub what kind of gloves are those ? Do they help reflect more heat ?
I'd like to see how you'd mig weld 1" thick A514 (beveled or fillet) in flat or horizontal with 90/10 gas and .045 Hobart Fabcore 1100 wire and/or .045 Hobart Fabcore Edge D2. I weld it a lot at work sometimes run into issues.
What thickness material was that??
