Bob Moffat has such a calm way of explaining and teaching. Such a great instructor.
💯
Absolutely!
Still can't believe this type of education -tutoring is for free for us to watch .Thank you Bob
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.
I enjoy these videos since it's been almost a decade since I was in college for welding. These are great refreshers.
. Thanks for taking the time, for the few of us who actually use this as a learning tool. You are much appreciated!
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? :)
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 :(
Intoit One of the better instructional videos. Just plain hands on teaching, very patient and good.
Bob is such a kool, helpful, and humble guy. Cheers to you sir! 🍻
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
In addition to the outstanding content, you GOTTA LOVE THE OUT-TAKES!
What a couple of Legends, Makes you damn proud to be in the Industry.
Overhead welding is definitely something I need to work on this winter. I really need to get my everlast welder out and practice.
Second on the NR232 wire. used a 5/64" on a structural job out of weld school. big change...wasn't all that great at it. love to see you guys use that wire for sure.
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.
Mancub you're one lucky guy I to have Bob teaching you welding!!
Many thanks Mr. Bob, and like the way you teach and talk. You are the greatest in welding as Mohammad Ali did boxing. Much peace to you
Thanks for the tips , got a 4f test tomorrow . Cheers Bob
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.
Thanks...Bob Moffat..I have so manny learn about you're lecture and actual weld.
Thanks Bob good lesson....Happy New Year to you and thanks for all the great welding lessons in 2018.
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
Thanks for the nice video.
Happy new year to the Weld.com staff and all viewers.
Happy new Year guys.
I really appreciate the knowledge you share right here.
Great content as always. Keep up the good work!
Happy New Year 2019! Thanks for the great content!
In the late 70s-early 80s, when I worked for Chromalloy GulfCo and Fish Engineering, we used the Lincoln Innershield machines with nickel alloy Fluxcore wire and no gas. We built jackup oil rigs in dry dock for several different drilling companies. Flat, vertical and overhead were required for certification with x-ray and bend testing. We couldn't use gas because of the wind on the gulf coast and I've wondered if gas would have been much help. Apparently it is in the shop. Thanks for the informative video.
A few years late on this but there are self shielded and dual shield wires
Thnx for the helpful video guys, from Perth Australia
Great Video learned a lot it was nice watching you teach him more helps learning easier you all da mans 👊🏻🙏
Cub says the coupin cooler rolls real nice. Translation: "We had riding coupin cooler races at lunch today!"
😆
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
Excellent video. I like the postmortem. It provides a good learning opportunity. Thank you
Love this style of video! Learnt so much more.
Great video. I am taking a night class in welding (intermediate class) we are just starting out of position. Thank you
Good coaching learned quite a bit on his Mig running.
Such a good teacher.
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
Lol..the bloopers!! But thanks very much needed pointers at my current job
Nice closeup of weld puddle! Happy New Year
Let's see some NR232 or 232 self shielded FCAW.
As a headphone user, the audio is switched left and right. I love the videos and always learn a lot. This is the only weld I had trouble with in my classes.
Great review & techniques!
Weld.com Heppy New Year from Poland
Can we get a beginners video on fluxcore? Settings, troubleshooting, things to look for, etc... Thanks, love the channel!
Another super weld vid , hope cub liked his crimbo pressie , don’t do mig but always good to have an idea
I always found with gas shielded flux core u can manipulate really easy and make the look better as well as less undercut as buddy kinda had there
Happy New Year Bob / man Cub Weld.com 👍
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..
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!
Was wondering if you could show some gas welding we gas weld anything under 2" pipe
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)?
I use the hobart arc 71 0.45 great wire to been doing 5/8 steel no problem
I watching these videos to pick up some pointers, looking to go from pipe fitting into welding, looks to me like rather than moving his body, he is twisting the shoulders resulting in a change of angle with the gun, the beads seem to go from wide to thin then back to wide as a result, this would result in a very rough toe line if it was stick welding?
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
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.
the Cub ,,, he is coming around , Happy New Year to all there,,,
He's not half bad!
Hey i just got into flux core welding for small around the house, ive used stick and mig a lot before doing projects to sell but i wanted to ask, do yall reccomend using nozzle gel for flux core? Im definitely going to try anti spatter but im not sure on the nozzle gel
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.
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!
Duel shield Flux core with c25 can be pushed or pulled @ 5-10°
I love select arc wire. Only thing I use in my 12vs
Next lets see a tig welding video like this! Keep up the good work!
When I do o/h I always flick it back a bit, seems to spread the weld nicely.
Hey Cub what kind of gloves are those ? Do they help reflect more heat ?
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.
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 !!
I push flux core all the time, never had a problem
At 1:55, that angle is called the ”Work Angle". The other, travel angle.
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.
Could you do a video on running a bead up hill on top of galvanized costed 7018/ 6011
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.
What should be the best setting for 1.2 fillerwire overhead fcaw sir?
I run the same wire every day and usually push. Seems to work fine.
That bottom bead on the second and third pass is always the killer, gotta put a slight push angle on it to keep it from rolling
No you just gotta keep the plate from overheating that’s it. Never push
Where'd Jr. get those spiffy space gloves? Good video and nice weld btw
What would setting be for 1/4" to 3/8" material.. volts, wire, gas??
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.
knit picking welds looks good
Who wants to grind I don’t lol 😂 awesome job guys
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
How do you do it when you have to overhead weld when it's flat?
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
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👌
Happy New Year Guys! Great video! Any chance of any over head stick welding in the future? Thanks Bob!
Outstanding
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
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
First question do we push or pull? 1:18.. Cub.... you drag...
Would be nice to see a 1/16th wire dual shield flux video. Any position.
Good video
Nice brother!!
bob happy new year
Can you weld flux core up hill
How dose this apply to self shield?
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.
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.
Can you well uphill with flux core ???
What thickness material was that??
thanks for the demonstration
