In this episode of MIG Monday we invited one of Bob's students, Clayton Lessert, to help us demonstrate a viewer request; 6010 downhill roots and repair welds. We begin with some 3/8" plate beveled to 30 degrees with a 1/16" gap. The machine is set to 85 amps and we are going to run a downhill root pass. During the weld, the rod will start wandering off to one side and we will have to grind it out and restart the weld. We will adjust the amperage up two - three amps to compensate for some lack of penetration on the backside. After the weld is complete, there is problem. On the restart, we didn't tie in to the previous bead and there is an inconsistency on the backside. We can't have that, so we will show you how to repair and overcome this to get proper backside penetration throughout the entire weld.

Through life I've had many teachers. In many cases the phrase; "Those who can, do. Those who can't, teach." applies. In Bob Moffat's case the opposite applies. This man can teach! He understands the how to do it, and much more rare, he knows how to teach.
He is the very best in his subject, and among a very few in any subject.
Thank you Bob
Willie B
Wish my welding teacher had been Bob
Hell yeah he goes nd grinds your coupons for you
Thanks for showing what teachers should do. Instruct, show the right way and let the student feel as though he is learning..good job.
hey Bob, industrial combo welder here. I think that what your teaching these guys is great!! can't tell you how many welders come through different jobs not knowing anything, only how to pass a test to get that money. Once they're out in the field, they do maybe one or two welds, but they never learn how to weld in a tight spot, or repair a weld. Good to see that students who go through you, learn what it's like on a real job!!
If I could make a request to pick your brain, I'd like to see a repair on pipe. Keep up the great work Bob!
Joshua Amaya We are going to shoot those soon.
Bob, I wish I could spend about two weeks just welding 6010 root passes, fillers and caps with you so I could go to the pipeline. You burn that root in good every time. You are one slick welder.
I know it's a fast freeze rod and I know the plate has a ledge ground on it to help prevent blowout but I'm always amazed the plate doesn't melt away on open root welding.
Had much chuckling when you told him you didn't ask your old teacher if he wanted dinner lmao! Your the man bob! Haha! You can tell that kids going places with what he has learned 👌🏼
Is he on Instagram?
Love your videos Bob. Im a journeyman pipe welder and I love watching your videos, they really show you know what your talking about.
Showing mistakes helps us very much. We do the same thing and it's great to see how to repair it. Great video. thanks.
Great video! Learning to fix and repair is just as important as learning not to make mistakes. I have screwed up on tests but managed to grind it out and pass the test anyway. Please make more of these videos.
what a excellent instructor and great welders
And it JUST THAT EASY awesome teaching Bob. Nothing better n this word than a person being able to,teach his craft to others.
Great video as always Bob. Nice to see the grinderless restart aswell, when we did open root in school we were not allowed to use a grinder at all.
great video! i like to see a mistake and how to fix it or see a common mistake being made and how to diagnose what went wrong. thanks guys!
Hey bob. I'd love to move out to America to come learn how to weld properly at your college and then get a welding job out there. I currently work as a maintenance engineer in England and practice welding in my spare time. Love it.
Great content from yourself! Keep them coming. Thanks
Scott
I was making the mistake of holding it too long to try and fill the puddle... causing blow thru constantly. I eventually realised I am not gonna end up with a thick bead, its not a fill rod it's a freeze rod. these videos and me practicing it helped me to be able to do open roots!! thanks Sir!!
Excellent video. I really enjoyed watching one of your students do the welding. It was refreshing to see how other than an expert (like you) gets along doing the exercise. In addition your excellent advice on how proceed and correct problems was very informative. Much more so that watching you do everything perfectly every time. I hope you can follow this format more often. Very informative for non-professional welders like me because I'm likely to make even more mistakes than your student.
Clayton: Good job man. And thanks for volunteering.
There certainly many vids of him making mistakes.I like how he not only includes them in the vids, but he points out how he/it f'ed up, & what his plan of action will be to correct it, & then the execution. Real world style exercises, kinda
That's exactly what needs to happen that way he knows how to fix it cause stuff happens. It don't mean you can't weld good cause everybody has bad days. The thing that makes a great welder is they know how to fix it and willing to fix it if something happens
Your videos are always helpful. Thanks.
That was an excellent video, especially with your student. Clayton is an excellent student seeing his welding and attitude and respect are very good and I think he knows your never done learning. Good job Clayton and Bob. Ed K. Cleve. Oh.
classic video Bob it took me a lil while to get the downhill groove welds down but now I love em. it's all about the rod angle and manipulation to keep It burning smooth
Jay b We are going to do more uphill too.
I’m a retired ironworker and took a job at the technical college But actually work with a dual enrollment program at one of the rural high schools and I found your videos and am learning a lot of teaching ideas from you. Thanks bud I hope I can be as good an instructor as you are to better prepare these young people for a welding career. Keep the videos coming.
Trying to up my stick welding game on my powerarc welder. Thanks for all of the tips. I hope I can remember and apply all of them.
good stuff i am a student and i like watching your videos makes me proud to be from kansas. keep the videos coming.
Great instructor. I wish you were local, Ca. I would have taken your class.
Answered, "... almost like bending". Got it. Now I have to try.
Viewer Request: Can Weld.com do a video on stacking 6010 beads. Basic beginner stuff. I ran a plate yesterday and it was decent but I'd love to see a technique that is easily repeatable for strong welds and good appearance. Is there a better technique than whipping forward one rod and back half? Can we make an e to make it easier? I'd love to know how to fill the crater at the end of the pass and how to start a bead without a mountain of metal at the beginning. Thanks!
could you do a video on capping downhill with 6010 in a 6g position?
Super video. For us willing to try to weld from zero, your explanations are superb. I wonder, we that have not weld think of the arc as the space between electrode (stick) and work piece, are you actually touching the work with the electorde ? Hear you saying "push it" and looks like touching on the down side. Again thank you all for sharing your life.
Yes, on most of our stick welding, we are lightly touching the material with the rod.
GOOD STUFF LOVE YOUR VIDEOS
GREAT INSTRUCTOR
great video bob if u could do a vertical up sometime as we are only tested on vertical up here in Ireland
kieron 123 Soon
Hey, we run it all. Up , down, horizontal and overhead. We don't like overhead though....
any chance of some videos going into the NDT processes? Curious as to how they read x-rays/ultrasounds for porosity/IP/etc
We have some shot and are being edited. They should be out soon.
They're on the way.
Great video as always. Can you do some videos using an everlast stick welder? That would be greatly appreciated!
I'd like to see some as well!
Hey. I’d love to see a 6013 pipe root pass. Here in The UK 6010 isn’t as common.
I think the request you were answering was mine. Thanks for the video!
I hope that helps. Let us know if we can help.
In general it is considered a bad practice to teach people to weld with one hand. This one time I will make an exception to that general practice. Downhill is fast travel speed, I have seen people blow out the back side of the plate from moving to slow. Many times moving to slow is the problem causing lack of penetration and young welders will think that they are welding to cold. Sometimes this turning the machine up way to hot out of frustration will cause blow outs or even less penetration. Downhill is a hot weld but only about 15% hotter than flat position work. You need a short arc when welding downhill stick on the root to force the puddle back and up into the joint, if you run excessive heat it will be hard to maintain a short arc because the rod will burn off faster. It is sometimes helpful to weld with one hand on a downhill root, it is easy to get too comfortable and then not be able to move fast enough to keep the rod deep in the joint. When you go to one hand you can prop with the non-welding hand and focus on keeping the welding hand pushing in. Employ a 15-20 degree drag that big drag will use the force of the 6010 arc to push metal into the root side of the joint. The one hand technique helps also when you have a rod that fingernails, that means burns out of one side of the flux. Many times finger nailing can be stopped by keeping your rod pushed into the joint and gently but quickly rocking your hand side to side. One thing is rod positioning I always bend my rod over when welding downhill this just gets the stinger out of my field of view and lets me get more comfortable without being too comfortable. When you downhill you have to find '' your spot'' because things happen fast. Some people even run like the first 1/2 to 3/4 of the welding rod with a finger pulling down on the rod to force it into the joint and keep pressure in the direction of travel. Downhill is busy and fast. Downhill is easy it is just different so sometimes we get a mental block about one thing and that one thing is what makes downhill kick our butt for a minute until we figure it out. Just stay sharp and find your spot after you do that you will be set!
tdej80 thanks for the information my friend
tdej80 If your 6010'etc is fingernailing dip it in water.
Harvey Gonzalez Your welcome. Nothing I know about welding is secret. It angers me when I see a grumpy old welder who will not help other welders or welders in training. We should be proud of our skilled trades and willing to help any young people who are willing to work and learn.
Bob, I noticed that after you burned your first rod on down pass. Did you clean off the slag or did you just start welding right in the old slag? I guess my question is if you did the later wouldn't that contaminated the weld? You made have clean it off camera and viewers just didn't see.
On 6010 and a demo plate, I'm not worried. In the field or on a test, yes I'll clean it. You would be surprised though how well 6010 will weld right through it and not leave an indication on x-ray.
How do you guys bevel your plates?
Track torch and either oxy-fuel or plasma.
How long would it take for these guys to build or weld up something?
awesome! watching the backside of the joint!! that would be nice one eye on the puddle on eye on the backside :) thanks for sharing. pete
1 year as a student and making 36.50??! Most jobs paying that good usually require you to have at least 5 years Xp and some certifications
Excellent video Bob, I like it when things go wrong sometimes it happens, and you showed how to fix it. Just wondering, I noticed you didn't chip the slag off before your restart, wouldn't that cause slag inclusions?
On 6010 and a demo plate, I'm not worried. In the field or on a test, yes I'll clean it. You would be surprised though how well 6010 will weld right through it and not leave an indication on x-ray.
When and how do you clean the slag? Not between restarts? I'm liking the idea of using a twisted wire wheel for cleanup. I'll use a grinding/cutting disc for re-doing a weld I'm not happy with (as you did in this video). Not many videos show the cleanup part.
Harry Pehkonen If you hit it while the slag is still red hot you can just continue welding. However its better to clean it off with a wire wheel so you dont get inclusions.
Thanks Bob
I'm a refrigeration operating engineer and i am planning on teaching myself to weld. i just ordered the everlast 200dv . my question is can you do a video on how to create your own coupons. both pipe and flat . i have access to plenty of leftover pipe and angle iron. how can i get the 30 degree bevel on pipe evenly. Thank you in advance. that esab 235 has me reconsidering my purchase lol
Welding is not the only skill you have to learn. Cutting, grinding and beveling is a must if you want succes.
And you are an engineer, so theory and learning stuff should be easy for you.
One word of advice. Dont make it to difficult for yourself in the beginning.
Keep it simple with few tools. Grinding a bevel is not that difficult, and I don't think you need NDT anyway :)
Good luck :)
MrPONCHO467 it doesn't have to be perfectly at the angle specified. The bevel just needs to reflect what the pipe schedule is. For instance, it is possible to make a 2" schedule 40 look like a 2" schedule 80. All it really takes is practice. do a little bit at a time. To achieve the angle you said, place your grinder at about 45°, then reduce the angle ever so slightly, and you'll more or less have that 37.5°.
thank you
Where to go for spray welding knowledge?
36,50 USD that is a good salary :) High hopes for this young welder
Better dollars than I make as an IT professional and 4 years of university. There's not a year that goes by that I don't think I should have gone into welding or machinist.
@@byron7165 And that's after just one year.. The Welders I work with who are Mechanics as well all make more than $65hr. Granted the program is 5 years, but you'll come out of it starting at $44hr. Unless you're a Doctor, Lawyer or Athlete you aren't making anything close to that at the beginning or end of your college career.
bob is awesome
The training school near me it's only a year and a half long so almost two years but it will be worth it
Hate when the rod starts burnin flux extra on one side like a doobie that wasnt lit right haha yeah turning your wrist gets it tho
I would like to see the proper way to join 2 pieces of I-Beam? I have a 14,000lb GVWR 22' gooseneck flatbed trailer that I want to cut and extend by 5' and I'm not sure if there a different technique specific to joining structural beams? The frame is 4" x 8" x 3/16" 12lb per foot I-Beam. Thanks!
In school I had to do 6010 root 7/8 plate 3/32 gap no land 7018 cap. Any tips for open root tacks?
I need help!! I need to test for down hill 6010 root/fill/cap on 6G 6” pipe. My fill and cap are decent but I struggle with a consistent root it’s so frustrating. I run at about 85/90 amps. 3/32 gap and landing. I’ll drag the rod and I see both sides melting but the puddle won’t follow me down, if I try to “whip” it I’ll either get a pinhole or blowout the keyhole and make a fat weld inside the pipe. How can I fix this?
Can you please do a tutorial on some pipeline welding tests? Id greatly appreciate it👌🏽
nice video!!
Any chance we were seeing some magnetic arc blow in the middle, there? It looked like that a few times.
Good video in general, the root-eye view was dramatic, people don't show that very often. I really did learn a few things here. Very clear presentation.
On my run, I was going a bit too fast a couple of places and lifted back up into the pool to get it to fill in.
hey Bob! when you were running your root pass every so often there was a little flick up, why is that? I'm trying my darndest to copy your technique cuz you make some awesome welds, please let us in on that secret!
sennest I noticed that, too. On the first one, I think he was reaching for the rod to steady it with his right hand and inadvertently bumped it upward with his finger. I think the second one may have just been a twitch.
Rick M thank you!
Thanks for noticing that. What actually happens is I'm out running the bead a bit. It's not filling that V above the keyhole so I step back up a bit and keep at it.
See above comment. And , yes, I twitch now and again!! LOL
Bob Moffatt haha...don't we all?
what size rod were they running the root with?
Good
Hi Bob, why 6010 on the root?
bob, how the hell do you see where you are travelling? John from OZ
Bob what size electrode was used?
1/8" 6010
Good watch! Hey bob what gloves you got? I wana pair
Steiner Superflex. steinerindustries.com/tig-welding/product/steiner-0262-pro-series-ironflex-tig-premium-kidskin-with-reverse-kidskin-back-tig-welding-gloves-poly-lined-back-adjustable-cuff
What kind of gloves does bob have ???
Steiner IronFlex 0260
that kids a good welder
Yes he is! I have a bunch of good ones and some that don't follow instructions and struggle.
Young people can be very good welders! When I was at Hobart the instructors were mostly skilled like Bob is. You take guys that age that have been around the world of welding and back 3 times they can whip a youngster into shape pretty quickly. Like Bob said though you will struggle if you don't follow instructions. These instructors are trying very hard to make you look like a 5 year welder in about 1 year, so the information comes fast and you don't spend forever on any one topic. After paying close attention to your instructor the next best thing to do is not to waste any of the time you are given for skills drills. That practice time is super important because these courses are so compressed! Bob Is super kind to make videos of this quality covering these topics on a free basis. He is teaching many kids who are paying good money to be there. Many of his videos look a lot like the Demos our instructors gave us at Hobart. Much respect to you Bob Moffatt, Tim
Thanks for the feedback and support, sir.
I'll certainly try to do more with the students present. Most of the time we are shooting at times when students are not around. Nights, weekends, holiday breaks, etc.
Are you wanting to go to a welding school? Where are you now?
Dude I have no idea what I would do if I made 36.50 an hour
36.50$ damn I need to get enrolled in welding school!
Thought the guy did a great job. Stuff happens like this often and all you can do is fix it and move on. His first pass ever on that new machine and it was filmed. Imagine both played into that small mistake.
Woah - great wages. Locally here it seems like Welders max out about 18-22 dollars an hour.
Does oxyfuel welding just not exist any more? Like wtf
It's not taught in a lot of schools anymore, but Bob still teaches it to all his students. We have a few videos coming out in the near future on OA welding.
My set up for open root pipe is 50-55 amps, electrode negative, 20-25 bevel, 1.5mm land, 3 -3.5 mm gap, with 3.2 electrode. Works like a charm.
ps here is the video of welder whipping that road like a saber lol
ruclips.net/video/oAkku5Arq6M/видео.html starts at 1.00
What rod?
6010 3.2mm (1/8 inch) bohler ... But we use Fronius (transpocket 150 /1500 and 2500) machines that have 100 volts in open circuit. They can burn 1/8 rod at 48 amps (electrode -) with no problems. Very sharp/strong arc. Once I have tried that set up on Miller welder and it did not go as planed lol , arc was to soft and I did not like it. But I have seen 4 different setups for 6010 down hand pipe root form US , Canadian and EU welders , all different all works but this one works best for me.
Where's he working for those wages?
His job was in Nebraska over the summer. I think it was a contractor out of Oklahoma.
Always buy a machine for the future. If you don't have AC you can't weld Ali.
Dylan Bojumpkio watch our DC Aluminum video. While maybe not preferred, it is possible to weld AL with DC. Plus you could always go spool gun on this machine to do AL.
Struggling and he makes 36.50$.... wtf making that money you shouldn't have to hold his hand. Like my boss said to a kid "where did you go to school tulsa welding school. Go get your money back. "
