I havent welded pipe since i was 21. Im 27 as of thursday and havent welded but 4 coupons at the house. I had a weld test for AC CORP saturday. It gets bent monday and i believe i passed already strictly from watching your videos. This job is gonna massively improve my family's quality of life. Thank you for everything you do for our community bob. Youre the man, hope to meet you one day and thank you properly!
Update?

Best presenter ever on the basics of welding. I'm watching this six years after it was first aired. Still the best.
same,I just enrolled on a welding school and we just started last week.
Camera man should be REAL proud of that 10:55 arc shot!
William Wescott he would give Jodi a run for his money.
I wish it was slow-mo just to watch the weld metal drip into the puddle. A1 stuff
i totally agree, camera angles rock and these new angles are so helpful. Bob, your welding techniques inspire! thanks for the great job and even improving your already good work!
Thats some of the best Camera shots of a weld I have ever seen. Thanks
looks good Mr Bob. The camera angle on your weld camera was set perfectly. on one of the 7018 passes I could see the droplets forming the puddle.
I noticed that too. Great camera shots
Some of the best I've seen. I just wish my own eyes were that good when I weld with my everlast stick welder. I've gotten to the age where I think I need cheaters now to see the puddle properly.
The distance between the two pipes is a few millimeters?
@@alexrodriquez6451 The distance between the two pipes is a few millimeters???
Bob I'm fairly new to your channel and I have enjoyed and learned from your presentations. I'm retired and didn't think I could learn anything new, but you changed that outlook. Thanks for your time and effort. Great job!
When do we get a "Best of Bob" compilation edit? The man is fast approaching legendary status!
Are you for real!
he my master

"whip and nay nay" I'm dying right now!
Tyler Hensley I actually laughed so hard, my wife asked what was going on.
hilarious,I enjoy his commentary this man is one awesome instructor
Lmfao. That was the best. Bahahaha
Damn I shouldn't have read the comments first lol😒
Lmao 😂 💀☠️💀
Damn you Americans have it easy with your fancy 6010 rods, here in Scandinavia we run 7018 all the way using a remote control in one hand. Bob you are a savage either way buddy, great job.
I was afraid I would never see anybody that was left-handed welding, I thought I was the only one.
Tekoa, I´m left hand and try for a time weld with the right too, need practics for training the mind and hand. latter is like just your good hand.
Don't see why being left-handed would be a problem, other than someone having personal issues about 'oh NO, not what I'm USED TO, different from ME!'. Maybe need a grinder with the handle on the opposite side, big whoop.
There would be some welds having a leftie would be very helpful for (left corners and such).
Learning to be good with both hands will be helpful for welding into corners, around pipes, etc.
I got yelled at everyday when I was learning because I would practice lefthand. Now I'm a pro in any position with either hand. It makes life easier..
Thank you Bob. Please discuss 6010 uphill vs downhill. I believe the pipeliners union entrance test is all downhill.
workwillfreeyou uphill testing is a lot of refinery work processing. You will find 6010 uphill in refineries. Some say 6010 uphill provides more strength. I don’t know if I ageee with that. Mostly everything pipeline all downhill work.
Pipeliner is 6010 root downhill. 8010 out all downhill
@@TundraCamburg would you say uphill is for structural, downhill is for flexible?
@@DatBoi-mo9vc downhill is just for speed. 6010 runs just as well up or down. Up puts a heavier root in
really great recording of the weld!!! awesome weld too, I just started school for welding and I am really learning a whole lot from just watching your videos!!!
You need your own show on cable! What a team.
your a great pipe welder bob,those passes went in there really nice and hell yea camera guy has his stuff together..thanks Bob!
jeremy doblinger I used to be WAY better in my younger days.....
buenas tardes soy de Venezuela pero vivo en chile desde hace cincos años soy soldador multiproceso sus videos son muy buenos he aprendido con sus consejos y la practica de todos los días lo felicito
Another great video Bob and great cameraman shots. You've done your time and I can truly relate to the one knee down pain. You need to get a nice knee pad that lays on the ground, covered with some blanket, makes a world of difference. Also have one of your crew get you a small fan to keep air on you in the summer heat, again you've done your time, now be comfortable while your teaching, just my 2 cents. Thanks for the great instructions.
Professional welder, you're my mentor
The distance between the two pipes is a few millimeters
Great footage & quality! Videos keep getting better your the man bob.
I'm currently enrolled at a welding school and I have had 0 issues on any positions, but this 6g is killing me! Failed both guided bend test attempts and cert test😒. Definitely going to be trying to take your tips, we are also on 6 inch schedule 80 as well.
6g was a breeze for me. But I took 6-8 weeks to move on from 5g thanks to that bottom part of the root pass.
@@solomonstello funny you commented. I haven't touched a rod in over a year and a half. I'm all tig now😂
I still fuckin hate 6g smaw😂
Really good video I like how him explained 👏 I'm going to take my 6g test this Monday and this video helps me a lot
For you apprentice pipe fitters out there here is a little thing that may come in handy.Now everyone knows that the take up of a 90 degree pipe elbow 1 1/2 times the diameter thus a 4 inch pipe takes up 6 inches but some fitters have to look in the blue book for"takes up" on 45 degree elbows.No need.Use this simple method in your head, say its four inch.Start out with 4 next half of that and so on.Then Add the second and fourth number.Thats the take up.Example 4,2,1,1/2.Use 2 and 1/2 The second and fourth numbers.The take up of a 4 inch 45 Elbow is 2 1/2 inches.Works for all sizes.Also a experienced fitter know that when you weld a 90 elbow it becomes a 92 degree elbow from the heat.If it has long legs it amplifies the amount it is off in the field.Therefore when you fit it together to be tacked put a wider gap on the inside of the elbow.If you are welding it yourself you know how much bigger you can make it. Otherwise you may be off quite a bit on say a 15 ft run.Now if it is off you still can fix it with heat from a rosebud.Heat up the outside of the bend very hot ,them when you put cold rags on it it will bend backwards further than it was before.This is how welders used to deal with piping going going to pumps with brittle cast iron housings to relieve stresses before there were flex pipe spools .
The distance between the two pipes is a few millimeters?
You go a long way "around the barn" with that 45 degree fitting take out. How about shortening that up by multiplying the pipe size by 5/8ths? I was a young squirt as a pipe welder when my fitter showed me that old method. I looked at it and asked him why not just multiply by 5/8ths. He swore to me that it wouldn't work on every size pipe. It does. . Also, that stuff you wrote about the 92 degree--------------------if you put strong tacks on fitup and welded from the inside towards the outside of the fitting, it will never draw. If you are working high quality piping, such as nuclear code welding, that rose bud stuff and such is illegal.
"the- camera guy wanted to see whip n pause.. whip and na-na"😹😹😹
Being able to actual see the weld burn through the camera lens helps to visually harness control on your movement and what to look for puddle wise, tremendous quality. Great video thank you. First 6G test ever in 6 hours... Can't tell I'm nervous at all huh 😂
Thanks Bob. Just something to add, I always tried to start around 5 o' clock, never at 6.
don’t ever question bob 😤
To me Bob is the ultimate best welder everrrrrrr.. the smoothest, most awesomest welds i've ever seen..truly beautiful..so beautiful it can make many a grown welder cry in admiration...i mean, it's extraordinary, and yea I got the feeling that Bob with his modest self will just shrug it off and say..: hey, anyone can do it with good practice and technique but truth is,,, no Bob they can't..not the way you weld, they can't..a pal and i was talking the other day about getting into welding and I said. dude ya wanna learn welding, then learn from a true master.. go on you tube, type up Bob Moffet and learn everything he says..
arnold glean most awesome*
Hello mister from Athens,you really professional ,I am mechanically and I understand very well what you do ,really good job,thanks
could you go over body positioning? I'm having a bit of trouble with my cap and it's just because I'm not comfortable. think it's more so on cap from different angles to prevent undercut
The distance between the two pipes is a few millimeters
Tbh I’ve been welding for a while now and When I was learning we always got taught abc (always be comfortable) but that’s like finding a needle in a hay stack when you’re in the field. For beginners I would just prop your non dominant elbow and use you’re fingers to steady you’re dominate welding hand. Pretty much the go to. But and the end of the day 90% of the time you’re gonna feel out of comfort
I'd like to see you guys try a cheap, scrappy machine and how to deal with bad voltages etc. Maybe even one of those microwave oven ones!
LOL "whip & nay nay"
Well done, professional work
Who else is in high school and wishes we had vents like his
Another excellent demo by the Bob Father. Thank you for shanking the info. You make that look really easy and I know for a fact it is indeed not.
Thank you Mr Bon, you made me learn more about welding , but am still looking for company i can work with , i want to welding school in portharcourt.
Thank you for this lesson. I still in trade school and were using smaw with 6013 rod only. I hope you can make some videos on 6013 oh how to weld on flat position, vertical up, overhead. Much appreciated
This was just beautiful! Good video Bob
The distance between the two pipes is a few millimeters??
Simply amazing thanks for sharing 🎉
I need friends in this field. I also work in welding and I love it.
Great arc shots there
Thanks for uploading these type of videos!
Enjoy the vids and lessons. amazing camera shots of metal deposit.
You camera man first run actually got the nice shimmering pool on the first go, the redo di not come out but it was cool to see it happen captured on camera. Thanks
BoB Moffett you are my absolute favorite excellent welder
HAY BOB,YOU RUN THE BEST ROOT PASS I'VE EVER SEEN WITH E-6010 UP HILL ON PIPE,SIMPLY,TO THE POINT,YOUR NOT FIGHTING THAT KEYHOLE AND WORKING THE SIDES LIKE THE LETTER"U"LIKE MOST PIPE WELDERS DO.LOOKS LIKE THERE FIGHTING IT,YOU YOUR JUST DRAGGING THE ROD,EVERYTHING HAPPY GO LUCKY.MAKES MORE SENSE TO ME.-HOW COME YOU RAN E-6010 FOR A HOT PASS INSTEAD OF E-7018 3/32?-KEEP UP THE EXCELLENT VIDEOS ESPECIALLY ON TIG,MIG AND STICK ON PIPE.HAVE YOU EVER TRIED FCAW-G AND FCAW-S ON PIPE?I'VE ONLY HEARD OF FCAW-S DOWN HILL FILL AND CAP(COVER PASSES).
Very nice, Im a second yr student in Illinois, thanks for the advice.

Bob, have you done any 2” sch40 carbon videos? 6010 root 7018 rest of the way out. I’m having trouble on my caps on 6g and can’t figure out what I’m doing wrong. I just passed my 2” sch40 6g tig test and next is the stick on 2” and I need some pointers. My cap keeps “sagging” to the low side.
The distance between the two pipes is a few millimeters?
Like for the dress shirt and tie weld!
Hi, you were running 1/8" 6010 for your 2 root passes. First one with no oscillation, and second you were oscillating. When you went to the 7018 passes were you using 3/32" 7018? Also were you allowing the pipe to cool between passes?
Thank you Christian
Can you explain some uses and practical applications for some of the more esoteric welding rods, like xx14, and xx16? They seem to be pretty popular here in Europe (Scandinavia specifically) for pipe roots, whereas cellulosic rods are almost impossible to come by unless I special order them. And maybe do something on any other more specialty/out there/rarely used carbon steel rods that don't typically see much use if that's possible to get a rundown on, just for curiosity's sake?
that was great i like to close my gap use a lighter land i the field that speeds things up. i drag my root. hot pass with 7018 feel like it is cleaner, and stronger. that machine runs smooth. i was also a aws cwi. arc strikes are not aloud in are code the grinding has to be kept to starts and stops and feathering tacs, on tests. great job that should help people. the thing i would say is every welder is a little different have to do what works for you.
Bob,
Thanks again for a great video. Any suggestions on pipe beveling and even fit up?
Thanks,
Tim
Awesome video. Im currently taking my pipe welding school. Got a question. My instructor told me to weave the root, but i’m blowing hole, making my landing a big hole. Should i stop weaving a root pass?
You want to only go fast across the middle and pause on edges of the root gap where your base material is thickest
I'd like to see an entire video on just ensuring a good even tack up of pipe and structural tubing with open roots no inserts.
I can't do it reliably to save my LIFE
you sure that is sch 40? wall looks heavy from the top view there
Молодец мужик жму вам руку и ставлю лайк.
radical! Our WPS is always downhand on waterlines with 5P
Can you do video on 7018 push?
👍👍👍...хорошие руки+хороший аппарат+хорошие электроды= качественная работа!!!
Bob when you talk about the keyhole what do you mean? Asking for a woodworker friend
What kind of good is that, and do you recommend it for field work?
Sir, I have never done this 6010 root without the whip back and forth. I have a weld test in the morning doing this. Not sure after watching this video if I should whip it or not. Ive always wateched u. I didn't expect to see this. Any suggestions
It depends if your keyhole is opening too much if its consistent run it smooth and whip it to build momentum for the growing keyhole
You Sir can weld the cameraman is very good as well
any chance to see practice pipe stand and clamp setup? - is this shop made or purchased? thanks in advance
When and where is this procedure ever used? Me personally have only tiged all the way out or if sch 120 or greater carbon tig root and hot 7018 out or for chrome tig root hot 9018 out
Nice root..had to internal coat many "spools" sandblast and coat.
Provided your weld procedures allow for that higher heat input
well that is NOT the 1965 Montgomery Wards buzz box that i have... my question is why start with 6010 rod and finish with 7018 rod... wouldnt 7018 do the same job from start to finish???
6010 best for root it burns through paint and rust
6010 is used for open roots/gaps because it's a fast freeze rod. 7018 would want to fall in the gap without getting proper breakdown of the edges of the pipe.
Excelent master, thanks very much, you are the best
Hi!Great quality tutorials with those different camera angles and views...this channel should have Spanish subtitles also...it would be great...
your welding looks great I see why u bend your rod's nice welding.
Hello, got some question about stick welding, when i set current to certain amps like 80 - welder keeps 80 amps while welding, but when the electrode sticks - then amps go up to 220~ The welder is mig/stick inverter, there's switch to set off mig and turn to current control in stick mode, but it looks like it somehow remains in constant voltage characteristics. What do you guys think?
The distance between the two pipes is a few millimeters?
Sir gap is 2.4mm or 1.6mm how to define gap and welding rod size does that depend on uphill or down hill
hey man how do you run a 8016 root and fill 6g fillarc 88s rods real fluidity and hot running
also 2nd question. there is no spec on 3/32 vs 1/8th in rods for your 7018 on the 6g up hill test correct? was told different at yesterday and wanted to check on that
Hi. Why are you soldered?
When you drag your root how can you tell that you're getting proper penetration and keeping your keyhole even? I've only tried once and I felt like I was guessing the entire time and it ended up too heavy. I whip and pause m 6010 open root.
Its all with experience, if your weld is not going in uniformly you will feel it when you are welding and your weld puddle will not flow. Main thing with stick welding is to keep your pool consistent. once you start penetrating and get in a rhythm you wont lose it and when you do you will know. Hope this helps.
Can you easily weld 6010 with welding machine that does not have support for it?
My problem is I think I could keep my rod in the middle at a steady speed and I've never welded before
I got a dumb question are these pipes used for like high pressure gas or air or are they structural
I believe Bob could fit for two welders or weld for two fitters.
Bob, where can i get one of those pipe stands like the one you have here? To practice 6g pipe at home
Thank you Mr Bob , The sticks are from 3/32 ???for all passes??
ivan mantelli 1/8" 6010, 3/32" 7018
I just replayed that root like 7 times
Could you do a video on restarts with weaving, im having trouble with the restarts
Jared Jones if I need to restart I might as well throw it away. Can’t restart for shit
@welddotcom could you do a video on fleetwelding?
Please clarify what fleetwelding is.
Nice welding and good instructions , you sound like Johny cash 😀
Would absolutely love to have him as my tutor
So I see some people using 7018 for the hot pass what are the pro and cons of doing so
How do you make the two starts on the bottom of your cap blend together with no lack of fusion
will it be possible to penetrate good in root pass using e6011 on 6 inch sched. 40 pipe with 1/8 landing @ 3/32 gap. thank you. Bob Moffats
Good video, lots of good information...I saw the camera guy in the background of a couple of shots with a short sleeve shirt. Long sleeves might be better PPE.
Camera guy isn't welding.
Do you run your roots with a 3/32 or a 1/8 typically?
Is there good money to be made in welding?
I use an esab 250 migmaster. love it
De que medida es el electrodo con el cual hace el root? Y en que polaridad está? Por que parece api polaridad directa pero lo hace en ascendente
@4:00
"hot pass" with 7018? Here in the UK, ive never worked to any procedure that has called for a 6010 hot pass.
The more common fill/cap rod for low to mid pressure pipework is a Vodex 6013 after a fleet root. So after root pass with 3.2mm fleet, just switch straight for a 2.5mm vodex and run it in on the same amperage to strengthen the root.
When using LowHy fill/cap for mid to high pressure work, it's 99% of the time either a tig root and hot pass, or a 7016 lowhy root.
