Tips that might just help you pass a 6g pipe welding test. this video is about the root pass and tips for using the "lay wire" technique. there are definitely other ways that work but this is one technique that has worked for me.
10 years ago... I watched this when it first came out while I was in welding school. These videos helped me a ton. Thank you for your hard work all these years.
i want to personally thank you for doing all of these welding videos, they have helped me a lot. im 18 straight out of high school and i just passed my first weld test for structural MIG welding and i got the job. Thank you and please keep doing these videos. if you could do a video on thick steel MIG welding i would greatly appreciate it. THANKS!!!!
HEY, PRO :) I AM A TIG AND STICK PIPE WELDER AND I CAN SAY THAT THE TIG FINGER AND A COMFORTABLE TORCH ARE THE ANSWER FOR A PERFECT WELD :) TWISTING TORCHES ALLOW ME TO WELD EVENT AT HARD TO REACH PLACES. AND YOUR TIG FINGER WORKS GREAT. KEEP SHARING VIDEOS, PRO... GREETINGS FROM BULGARIA :)
Jody, Never be ashamed of the "commercials". You are worth every bit of them!
Great job on this weeks video!
Every time that Jody puts out a new video, I learn something new. There are jewels of information throughout each video.
I am not a welder by any stretch of the imagination, but with each video, I am learning more and more. As a retired mechanical engineer, these videos make me want to take some welding courses....why....because I can.... :) One should never stop learning, Keep up the great work Jody!!!

Hello. Am new to your channel. You have good advice. Ty. I am a 65 yr old ex-gal welder. I was taught in welding school in 1988, to start your welds in an "out of position" position, so that by the time you end it, you can end your weld properly, with less chance of repair. Like grinding out porosity created from bad starts and stops because of fighting for a comfortable position in the end. It creates less tension. And we all know... tension is not your friend when welding. :-)
What a great overview. People usually skip the planning part which indeed saves a lot of time. love from india🇮🇳
Jody. Great tig root talk and walk
I am an old General dynamics EB electric boat welder always can learn new things
You do a great job
Like you Jody I am still welding after 40 years and learning new things from you
USN retired Vet
yes that is a leatherman tool. I keep it close all the time. snipping wire, cutting stuff, opening packages, and an occasional beer too.
I ordered these things to specifications. and yes after a while you can pretty much eyeball and tell within 5 degress...but I did put a protractor on it to check it....and 37.5 deg angle is specified by asme section IX code book for welder qualification.
I have a couple of vacuum tank welds coming up in the next few weeks, nothing that will be inspected, but nothing I don't want to be as good as it can be- this is great information on the technique for a pipe. Thanks so much for sharing!
The person that tested me on my first tig root 30 years ago made push the root out like that . I did it a little different than you I walked the cup ,and made are tight weave . Like what you show you are an excellent welder . I am also a cwi it really bugs me when testers try to go a little farther than the code . The first weld I inspected looked real good . The person in charge of the R stamp said to alow no undercut but the code alows some.
One major thought that has helped me pass many (all) Nuke sites is to Stay on the wire. Some said that they had suck back after the hot pass. This is most likely due to hitting the bevel too much and of coarse staying to long in that spot. I walk the cup and as long as I keep the tungsten pointed on the wire, it comes out smooth a piece of glass. I which You Tube was available in my day. My man did an excellent job in this Look See!!!
what do you mean to "stay on the wire?" i'm sure that has something to do with the filler rod but not familiar with the term since I am just a student learning how to weld. ( I am pretty much forced to teach myself since my instructor sucks. he is rarely around and mostly spends time looking at his phone. I also don't know what "hitting the bevel too much is." please explain if you could be so kind.
in order to fully penetrate and leave a smooth weld on the inside. also, the pipe welding codes call for a gap.
What size cup were you using
Thanks for sharing. I busted on my last schedule 120-6" 6G pipe test. It sucked! I drove 5 hours to get to the place and the welding equipment they provided was JUNK! They wouldn't provide any help, tools or even answer any questions. l had to do three sample coupons. Frist one was TIG root and hot pass with TIG filler and cap. Second was TIG root and hot pass with 7018 filler and cap. Third was 6011 root and hot pass with 7018 filler and cap. Luckily I had brought all my own grinders and stuff I needed. I used my own TIG torch and electrode stinger... their stuff was broken junk! Anyways, it took me 9 and ahalf hours to complete everything. My welds looked okay, so the inspectors did not run me off. They cut my first coupon up and set the first test sample in the bender and as I watched... it CRACKED!!! And that was it. See you later and down to road I went. That company was Kiewitt located in Corpus Christi Texas. I have a 6" schedule 80, 6G pipe welding test on Monday. It's 6011 root and hot pass, 7018 fill and cap. Hopefully I can pass this test for the job. I haven't welded on a single pipe since I busted at Kiewitt back in May 2013. So it's been 4 years since I have scratched an arc on any pipe... God have mercy on me for ALL of my past welding sins!!! LOL. :D
I'm a rank beginner but I've found your videos immensely helpful, even the ones on techniques I'll likely never use.Watching you videos I'm itching to get a real welder like the Everlast. Thanks ever so much for all the knowledge and effort you put into these videos.
IF YOU WANT TO GET A REAL WELDING MACHINE LOOK INTO A CK MT 200.THEIR MADE BY THE SAME COMPANY THAT MAKES TIG TORCHES,CK WORLDWIDE.JODY SELLS THEM HOOK UP WITH HIM.
Thanks to you I passed both of my certifications!
In welding school on 6G pipe now. I weave and have good success with it most times, but have problems with a below flush root in some places. The locations are inconsistent, but my technique is seemingly consistent. The pipe is donations from the local shipyard. It's pre-beveled and is the same coupons they use on their testing. May give this technique a try to see if it helps.
Man, I wish this video was published when I was doing my TIG pipe stuff. Excellent stuff as always.
Wow Jody. Great job on the videos this past few weeks. I recently passed the D.1 overhead test and the 6g 2inch pipe tig root stick all out in the same day.
If you learn the cup walking Technic, your inside weld would be like a machine. I orbital GTAW as well. Once you get the perimeter set right its awesome. The Technic above's difference is the free handed feeding style, almost. I lay the wire to the contour of the pipe and not feed it but weave over it directly in the center of the wire just as above but allowing the cup to guide the welding time and direction. When I seen it done by the orbital process it verified this method for me. My timing,as mentioned above, is much faster with the cup to keep the consistency.
Hi KRS 1, you answered your own question at the end of the statement about "hitting the bevel too much", by doing that you create suck-back or flattening of the weld inside. The instructor in the video mentioned travel speed also so you need to pay attention to your speed which is fast but not rapid and keep your torch on the wire, in the center if possible as you Walk the Cup. In other words don't race past your puddle which may cause too large of a keyhole. My method is using what is called "Walking The Cup". Look up a few You Tubes on this. If we have a heavy item and want to move it we walk it left to right till its in place. Walking the cup is like that too, we walk the torch cup as if on its heel left and right but again in tig welding we need to find the comfortable speed. If we stay in the weld to long it will suck back. Temperature is key also, not to hot not to cold, very important. After your root pass then you can cut it up a couple of AMPs, not much though.
I didn't answer my own question because I said, " I also don't know what "hitting the bevel too much is." How is that answering my own question? I still don't know what that means. you say it creates suckback, but what is it? do you mean when you're walking the cup on the root and not progressing that fast and just staying in one spot a bit too long? can't think of anything else you might be talking about.
hello
hello
hello
Sir respect your efforts here BUT! here in Philippines your this accomplished of yours cannot pass the standard of our testing qualifications. Thanks sir God bless you.
i love the length of the video Jody, you should keep them around this long
seems to be a thing in Australia...
"Certificate No. 8G - Gas Metal-Arc Welding (GMAW) of plate and pipe "
Damn Jody. You should make a contest to all your viewers. Best 6G six inches test root wins a tig finger!
Thanks for the video, from Colombia, the good tig welding technique with good work quality.
this is really good stuff. I learned to weld many years ago with my dad stick welding. now I mostly do tig because the parts I make are all done in .063 aluminum. I am starting to look into certification so I can apply for an actual job and "weld" it to my home shop work, which includes milling, and welding proton guns for unlicensed nuclear accelerators. I want to be very familiar with the whole testing process because being under unnecessary pressure can't be beneficial to the task you're trying to perform successfully.
How in the hell are there close to to 300 dislikes in this video ??? This is CZcams platinum!!!!
Chines troll farm maybe
This video just passed 100000 views today Thanks to everyone who helped make that possible
This man makes it look easy I want to be like him one day
Super video
Find the videos for me teaching, because I myself have done a welding training.
The root seam looks great, good when you can weld right and left. I am a right-winger, one could "bend" around a root in a pipe to weld.
Greetings from Germany.
Up until my last job I have always beck fed the bottom and keyholed the top. I was laid off in NC so I went to a nuke plant in GA and laid my best root. It was slick. Basically a perfect 3/32 wedding band but they did not like 3/32 reinforcement. Too heavy. I was stressing out to put it lightly. Had one baby girl and a son on the way and not much $ in the bank. They gave me a second shot and I'd never used this technique but having seen this vid I gave it my best and passed both coupons. I would say if you have any skills you have to be drunk to screw this up. It is so easy.
I worked on this for a whole semester doing the root pass with 6010. Totally blew it.
Jody when I grow up, I want to be like you !!!! you are the best!!!!
Can't wait to try this tomorrow at the Hall... thanks!
yes, we do ship to Sweden
That fit up was incredible
Tank, I need an upload on how to pipe weld like Jody. 😂
This is a test I need to do ASAP . It’s $1000 and has only a 20% success rate according to the instructor . Wouldnt stepping the torch back and fourth cause pin holes? That’s what I’ve been told
Staying on the wire means not breaking the walls of the bevel down at all. As you move your cup lef and right ,stay in the weld as shown above. He does not touch the walls of the bevel at all, he stays on the WIRE
Thanks Jody for another one. Since we are making requests if u can ever do a d1.1 3G on one inch plates that would be sweet. I failed that damn test last week.
great job, I'd love to see more 6G tig stuff from you.
6:00 Who doesn’t have back trouble 😢
exactly how i weld my 6g! good video!!!
Keep up the awesome work. I learn something new on almost every video. I can sit though a few commercials ;-)
congrats on your certs. that was a long day eh?
I think you did a real good job Joe
Hey Jody, can give us some, "Do's and Don'ts", tips on how to prep pipe and plate, to get ready to take a test?
Why do you leave a gap between the two pipe ends? Why do you not "butt them together" to make the join? I'm not a welder (you guessed, right!) but I do simple repair and maintenance "farm" type welding and I find your videos really interesting and informative. Thanks if you have time to answer.
Just failed my b pressure test with tig root… I’m only a 2nd year, but I feel so defeated. 4 weeks of practice and failed for the first time. Have one more chance to get my c pressure ticket but hard to stay motivated.
At 7:54 i assume you were kneeling to weld at the 6 O clock position. Might be obvious to others but for newbies its an important matter to see how you get correct posture as without that you cannot do a good weld in the first place. I think there should be more emphasis on this point in youtube videos in general and not just yours. Thanks for great training. Mike
Where I test they make you run a good size tack holding your test pipe to your holding arm and then they come in and stamp your tack so they know it hasn't been moved.
Nice job, sound advice. Excellent vid.
Hello all. I am an electric welder for 6g pipes, ten years ago from Egypt. I would like to work abroad. We do not differ in wages according to your evaluation. Thank you.
My welding teacher made everyone learn to weld with both hands said out in the field you my have to use the other hand. I am left handed and learned all my life doing right handed so no problem
You make great videos for TIG guys, would love to see more DC Stick videos. :-)
Thank you for youre work and videos Mister...Hurry up! From Belgium...
I graduated with five certifications and aluminum tig being my forte'. Love it!! Was wondering, though, I'm looking to buy a new tig welder and am not sure what to buy. They've changed alot. Would you happen to have any advice on a good efficient welder that won't cost me an arm and a leg? One with a "foot " peddle? Has to do aluminum as well as other metals and run hot. If not, that's ok. I thank you anyway. Love your channel! Ty.
How to do this with pipe diam. 80 sm and with the not stable gap about 3-4.5 mm? This is the problem especially on the bottom.
3/16 gap works best for me...regardless of pipe size. I use a 1/8th wire.
I like to use Aluminum rod because it is easier to pull it back out
Jody, love your vids man, and thanks BTW. But please can you use metric measurements as well- the only 2 countries still using Imperial are the US and Burma...
What did ya do with your 1/8 wire spacers? I still mine in my work bag after watching your video with that little tip in it. Thanks again for another great video
your an awesome welder!!!
You teach very well! I also am a welder. You have great technique.
but I noticed your bottom half of the root pass looked concave Am I wrong?
At 2:18 you break off your spacer, then seconds later you have a totally different spacer that you twist and pull out.
Thank you your a great help I love your advice and videos . Appreciate it
Hi, Love your instructional vids,,,I have a question regarding the stick welding or fill up
of a joint.?.Wondering if you may have any tips regarding how not to get porosity on the overhead when using 7018 low hydrogen electrodes..Seems that I have experienced this many times over the years..Just seems to occur on the overhead like when you strike up your arc on a test comming off the six o'clock position. Not a good thing when doing the two inch test in particular..I've tried numerous methods but occaisionally still get porosity down there. I have taken into consideration rod angle, amperage settings, the surroundings like if there is a breeze, even magnetism of the fixtures that the coupon is attached to..checked out the electrode batch numbers and rod oven heat settings..The only thing I could contribute to this problem was the fact that the gasious shield that is formed when the electrode burns is heavier than air and thus drifts away from the weld puddle due to natural gravity..Any suggestions welcomed....Thank you Dber..
Shove the rod up into the puddle, alot of times a small deviation in the amount of arc lenght will give you porosity, so try burying it an see if that helps
Tip should have been ALWAYS DO YOUR HARD SIDE FIRST!!!!!! If you have a problem it is usally your hard side, also if something does go bad you will maybe be able to fix it before the gap closes up to much. Another big tip is PUT YOUR BIGGEST GAP QUARTER AS UR EASY SIDE BOTTOM QUARTER.
yeah you have no idea lol. pretty easy tests but hey i got pretty damn tired too. long drive back to the house because i got lost and my knees hurt.
WAOO NICE VIDEOS BOSS
I AM FROM INDIA
I AM IMPRESSED TO WELDING VERY NICE DOING WELD
What kind of grinder is that that you first used? I've been looking for one like that
another technique maybe ??
sometimes in test field we don't have a welding rod option.
sometimes the gap must be 3.2mm and the rod is 2.4mm
Chandra Defta backfeed
first of all I do not want to humiliate this man: D but unflushed shows the joutube people, the first error is the root, the root is made from 2mm to 5mm using the wire 2.4 mm tungsten eloktroda other thing going from left to right so-called zigzag system with the addition of strings as it works. I use depends on the amperage of 85 amps to 100 APERA accurately, 85, 90, 95, 100 amount of argon gas at 10 gauge. tnx
REAL PROFESSIONAL!!!
3/32" (2.4mm) 2% lanthanated
Good mr
You are an artists .thank you.
I wish I had joints like that when I'm at work, often the pipes are cut by noobs and have to be forced into position and gap varies from nothing up to 10mm. I feel more like a magician then a welder ;)
Thanks next week I m doing my trade test so I learn a lot
Jody, your amazing Bud!
Love your videos, have you done a 6g schedule 10 ss video yet? I can't seem to find it if you have. I'm having issues with my ss roots coming out way too flat.
Thats kind of like the Oxy acetylene process you maneuver your torch. heat the puddle back off the only difference your not dipping the rod in the puddle your just dragging.
Hey Jody,
Great videos, been a shop fabricator for over 30 year's and am currently looking for work. I keep running into add's for 8g certified welder's. could you explain what this test consist's of. Thanx
requested information in order to adjust the machine to the material to be welded agree amps, voltage, and choose gas welding material handling also can fit the torch movements welding position.
Thank you.
Hello sir am a welder i don't have a job pleas can you just help me please for anything like money i don't have food to eat just help me
muchas grasias a este gran samaritano me ayudado mucho sus video lo felizitoo
Hello, Student welder here, just getting into a little bit of pipe now. When you say your using 120A for your root pass, are you %100 down on your pedal, using all 120A or are you closer to using 90A?
What do you use for beveling/how do you get it so pristine looking, also what kind of setup do you use for recording weld shots ie do you just put a filter lens in front or do you use a special type of camera?
And the root of the weld +0.5 mm or -0.5 mm? It seems to be on the EU certificates require that the weld root was +1 mm, in the video i see -0.5 mm.
Iam a pipeline welder I love this
Stephen Amadi puto.pipe line haha
Jodi, any tips for stick welding a stainless steel gas tank?
I'm building one from 1.5mm sheet metal with 2.5mm sticks.
thanks
questions from a beginer. When you go take the test, do they assigne for you what your going to use? or do they just test you on all three? ( stick, mig, and the one you are doing). Can you also use your own machine or you have to use their own machine? thanks in advance.
Penetration not enough should be 1.6 mm correct if I m wrong
what do u use for beveling? can u make a video on differant techniques, and tool u use. angled torch, plasma, grinding or do u have a pipe beveler?
I've been a combo welder for several years now. I can tell you that you root pass does not have enough penetration. back feed the wire and have AT LEAST a 5/32 gap. I run my root pass at 110-120 with 1/8 wire. I don't let my tungsten go up and down. I go side to side. inspectors on oil refineries will reject that shallow root pass in a heart beat. it needs at least a 1/16 bead for the root. We weld our hot pass at 150-165 depending on the size and schedule of the pipe. Nice video by the way. I just don't agree with the weld or the technique. In real world tests, and x-ray shots in the field. That technique and root pass is unexceptable.
have you ever seen anyone weld pipe like this at the refinery? you suggested he backfeed the rod. do you mean put it at the top 12 oclock tack when welding the bottom or at the sides at 3 or 9? I don't put mine up at 12 to feed it into a root at the bottom.
when I start my root (the bottom). My wire is fed from 3 or 9 o'clock. Depending if I'm welding left or right handed at the time. From 10 to 12, or 2 to 12 oclock. I lay the wire at the edge of the bevel and feed the wire. Gravity will pull the root down from the top.
chevynation yellow do you freehand or walk the root? and which is more common at the refineries?
Amen, FINALLY someone that actually knows how to lay in a root pass. If you dont back feed at least the bottom of the pipe, there is no way to get proper root reinforcement on the inside of the pipe.
How do you know that's 35 degrees without a protractor or equivalent? I know you can get good at eyeballing things but.... Why does it have to be 32.5 anyway?
no e visto la primera prueba que no leden vueta al tubo hacy es muy facy cualquier principiante lo logra
Going for a 6g pipe welding test tomorrow and tips for me ?
Did pas ?
Yea
Nice . I'm a beginner
My too just finished school
Apete rodriguez
in canada we call your technique rod and roll stay on your rod on the root ensure tie in is there ....on the hot pass roll ovver the rod stay off f the root its spitting hairs cause it all has to be bonded yet dont want suck back
Where’s all the people saying you “have to backfeed “
I was wondering how far of a gap should you have between your tacks?
Im a tig welder and it has been a 10months till i last welded with gap that required the root and reinforcment on inside...i welded the stainless steel tanks and pipe that only required no root only full one pass...but now they are asking from me to do 45°degree angle weld (6g) with root reinforcment and i have tryied today and it doesnt go out,even though i keep the wire inside and go left to wright...what is your tip for me,and how to make a small ring on the inside like a 1mm of all around?
