TIG Welding 6G Pipe Root Pass

[@snowkracker]

My instructors keep telling me that I need more build up on the inside of the pipe for my root pass. But none of them can actually show me how to do it themselves.

[@HunterKimmel]

Just keep trying tig is one of things you have todo a lot

[@KennyInVegas]

I'm older than both these guys...these guys really are old-school great people who give their time and wisdom and make this planet a better place. Some day I'll get enough balls to WALK THE CUP

[@Welddotcom]

Glad to be of assistance!

[@Welddotcom]

This is a personal preference. I personally feel more comfortable looking through the inside of the pipe at a slight angle so I can see the wire and the inside of the weld pool on bottom. I have also looked at it from the outside while on bottom as well but it seems to take a longer to complete the weld.

[@Welddotcom]

That is correct. Move up on the bevel and lengthen the arc to decrease amperage and snap out of it. Since you are using a manual torch you may post shield with argon.

[@BrHck]

Oh man, this reminds me for my 6g exam! 45° 60mm pipe 3mm thickness and the top highness of thah pipe was same level as my eyes. You can't use wall to lean on or some other support. There are just that pipe, your shaking hands and three people watching your agony :) But I did it.... almost perfect. Love your videos, because no matter what experience I have, every time I learn something new and interesting.... which makes me better TIGer ;)

[@Welddotcom]

We get anything from generic to ESAB / Lincoln filler wires. What’s important is the GRADE for filler wire. We mostly use ER70S-6 for our carbon steel pipe welding with GTAW.

[@gorillawarfare7955]

Weld.com do have any video's on welding p91 chrome

[@Joseya_Pappachan]

A student from India... Awsome Tricks and Teaching I love it

[@alialhawra2235]

I am very confident. I have been working in the field of welding since 1992 and have worked in oil refineries and bridges stores, noting that I am a welder with electric tubes and tig

[@Welddotcom]

Lead angle on any open root pass regardless of position may vary. 0-15 is usually for structural fillet joints. I have not had much luck with a 0 - 15 degree angle getting the open root pass to progress (flow) upward. Try using the 25 - 45 lead angle and keep the wire on the leading edge of the pool for complete fusion and reinforcement.

[@sanjeetkujur1100]

Very nice technique. I love the way you explain about the root welding process. Really I love watching the video very much.

[@JustMike2791]

I thought that as well.Never seen it, much less tried it. The 6GR seems to lend itself to a small mirror. I tried the mirror and it looked like I was a novice. Practice, practice, practice they say. Good luck and best wishes.

[@powertothebauer296]

Thanks for sharing, looking what other welders do helps me hopefully improves my welding techniques .

[@kevinlainez3060]

The angle of that pipe is still considered to 6g position?

[@Welddotcom]

He actually did weld the right side. unfortunately we were pressed for time and were unable to capture a good arc shot. we can post what we did get if you would like to see.

[@SuperDougie89]

Gonna try this method tomorrow. Practicing 6g this week for my test-plate which is coming up soon.

[@Welddotcom]

This answer requires more characters than allowed by KZbin. I created a new thread on the forum specifically for this question. The link can be found at the bottom of the description. Thanks.

[@JustMike2791]

I sure would like to thank you for the informative video. I've been a welder for over 20 years and I can't seem to pass the 6G carbon test. I'm AWS 6G certified, (I paid for that waste of money) but when I go to take the test my root is ok but my hot pass and stick cover suck! I have my own 200 amp tig rig, I'm now going to get a DC power source that has finite controls. Practice, practice, practice. I know I can do it and I'm sure by watching a few more of your videos. Thanks again, keep it up!

[@snowkracker]

Did you ever pass it?

[@JustMike2791]

@@snowkracker Yeah, just did some hood time and it was easy.

[@kennyglover2336]

This is a blessing to me thanks guys I have all structural experience but I'm confident I can do this

[@dgw9051]

Great video, I'll start practicing that position tomorrow after work. Thanks!

[@Welddotcom]

There is no need to purge carbon steel pipe or plate. Simply clean the material about ¾ to 1 inch away from the root on both sides.

[@jessewane8191]

The test is the easy part when u get in the pipe rack with a safty harness on is when It becomes harder

[@JoelZWilliams1]

Very informative. Excellent craft skills.

[@laurenceaoun6191]

I believe he is very good welding teacher. And handy man i wish for him good futur regards

[@pizzaWelder]

I like the technique of feeding the wire through the inside of the pipe... Very cool. Will be interesting to see it when restricted. Thanks for another great video. Keep em comin

[@weldermike7017]

That was a great video, thanks for sharing. That guy kicks butt!

[@InchFab]

A legend is (was) born.

[@makavelimexicano]

Thank you for posting this video. Very detailed on positioning. I myself have the 26FV miller tig torch and trying to get the hang of this large torch.

[@craigbosko2229]

DEPENDING ON HOW HIGH OF AMPS YOUR USING,TRY LOOKING INTO A CK TIG TORCH.CK WORLDWIDE.COM

[@AdamKoestline619]

Why is it when I'm doing the root it doesn't seem to flow right? Like it seems like the puddle comes to a standstill and the keyhole just gets bigger and bigger, then I have to dip the hell out of the rod over and over and then of course my tungsten ends up getting stuck

[@joedragaux8695]

BOB is the REAL “Mr. TIG”. Bob is a real bad ass old timer. Everything he says makes sense and has wisdom, no bullshit. He actually HELPS for cert. prep and practice. This other white haired pretender is a baby sitter. He is an insult to most people’s intelligence. A bullshitter. Its almost like there’s a bunch of five-year-olds watching and he tries to interpret actual welding stuff; or for people who have no capacity for welding, people who never actually going to get in the industry or have zero intention of actually getting a welding CERT. (he talks like he’s teaching ABC’s to people that can’t speak yet.). Other people must feel the same; never see that white haired baby feeder anymore. The new weld.com videos are bad ass! Thanks Bob!

[@boykiemotswapong3662]

that is wonderful sir one has to dip in the filler wire in write in the groove for sufficient penetration and also mind your preparation and and settings depending on the thickness of the filler wire and the thickness of the pipe.

[@ironmanlifts]

Good camera work.

[@Mr05sti]

Walkin that cup! Very nice good job with editing also!

[@dvil1264]

the tig and mig pipe welding were awesome the mig helped out a lotou guys I coudnt figure out how to get the root never thought a 5/32 gap if you guys could do one for stick welding pipe I cant perfect the root pass

[@pwmike]

I weld the bottom of 6g with the rod on the out side of my pipe.Have had problems with gap closing shut. Also i put four one inch tacks on bottom top and sides.

[@laurenceaoun6191]

Hi he is very good welding supervisor. I which him I believe he is professional 😉

[@frederickgill5677]

Bob is definitely a first class did u see that 1 /16 rod technique master old school burning he started from 6 went to 12oclock perfectly

[@Doodoosniff]

Thanks a lot mr. Tig especially mr. Bob. this video teach me more about root. i bet u use 60-70 ampere

[@chineduegenti8970]

Great job guys, keep welding

[@lorenacatalan3103]

what amperage/voltage range use for the root and you move the rod side to side o no

[@Pabcar9184]

please put sbtitulos in Castilian! Greetings from Argentina ha ha great quality videos and very good perception about the process tig!

[@mdataullababu4447]

Very good Welding.. I like this Welding..

[@FromThe3PointLine]

OK I have a question. If I am using a scratch start Tig set up, how do I terminate a Weld? Crawl up on the bevel and snap out with giving the bead a post shield of argon?

[@mdataullababu4447]

I Love Welding.. I work Welding in Malaysia..

[@paulboykin8898]

How many amps are you running on the root pass

[@nicvirgilcabalan8272]

Hi sir what's the advisable tacking. bridge tack or pretack for root? Sorry ro bother you im going to take gtaw im smawer

[@yurinunez7804]

Muy buena soldadura y muy buen video, saludos a los colegas desde Uruguay

[@assault_skateboards]

Root looks great!

[@Kypmczp]

hello and thanks for the video. firstof all sorry for my bad english. i try to explain my problem. this technic is working when the pipes are fit but what if there is some fitting problem i have a pipe flange is 2 milimeter narrow then pipe. but still i ned to weld it for xray how i can do this??

[@elizabethbraim3354]

What cup size are you using ?

[@kennyglover5095]

Why is is cup so small i have been using a 8 cup with 3/32 tungsten

[@AWoodworkersLife]

Enjoyed this video, especially the prep part. I`ve got a question though, at 8:39, isn`t the root protruding too far into the pipe on the bottom left area?

[@alexferraz4747]

if im not mistaken sum codes will allow about an 1/8. but it looks fukd cuz of low spot oround btw it wont pass XRAY the bevel lines on inside gona show 100.

[@jonnydang9559]

What machine are you using? I’m interested in purchasing a new one for home to practice pipe and weld roll cages

[@jacobwright516]

How big is your pipe wall, root gap, landing? What amperage are you using? I am watching from a computer with no audio so I can not hear any of your discussion...

[@MrIppon-fl6bl]

+Jacob Wright I heard in another video, same process in a 5G, same welder (Bob Moffat) and he said he was welding around 90 + amps and his fit up was 5/32 to 3/16 th's. Nothing about the landing but it appears to be 3/32 or less. Hope that helps

[@yanskyvillejo7105]

Nice and smooth

[@rodrigobalcazar9079]

este señor a la edad que tiene sigue siendo una persona muy respetable ,por como desarrola su trabajo ,se nota la experiencia en el .

[@andresmontolivo851]

What amperage do you root for?

[@toni_7571]

this video sure helps, thank you

[@rsullivant]

You know, I have probably watched this most excllent video 5 times. Matter of fact, I think it's the first Bob Moffet video I ever watched. I am just now noticing the Boomer Sooner weld cap. Need to find me a Longhorn welding cap - Hook'Em!!!

[@nuke7955]

Are you contaminating tungsten , by the way the flame changed colors

[@michaelrodriguez-fb8fr]

what size of cup did you use for the root?

[@rvseradoy]

Hello mr.tig. Just want to ask, how to tig weld a pipe that has a mismatch on a fit-up but can still pass an xray? Thanks

[@irfankhansnr7471]

Thank you very much for the upload Welding video very helpful to me thank you sir

[@rvseradoy]

Hi mr.tig just want to ask if you can post a video on how to repair a tig root pass. Ex. Lack of fusion and undercut

[@wajhirizvi592]

During the welding,how much gap required between the pipe and fitting???

[@GowitChaimongkol]

Can you make a clip How to weld Alloy pipe diameter about 20 inch and schedule 160 with the right procedure heating up before welding.

[@stevenmchenry8417]

Great job

[@Jasson77xx]

about what amps do you run the root pass for this gap 5/32 is it 100 or 120?

[@Jasson77xx]

please reply!

[@bkpickell]

Jasson77xx Doesn't the 6G cert requirements state that you can use 70-90 amps? I could be wrong, but I'm pretty sure that's what I read somewhere a while back.

[@robertmayo6339]

bkpickell depends on who wrote it. In the nukes our top is 150amps according to WPS.

[@lascoob970]

bkpickell depends on WPS...

[@lascoob970]

Jasson77xx depends on what you like and the WPS but typically 90-120 amps.. all welders weld different too.

[@Mrjoelaguirre]

I love welding

[@turtlewax3585]

Is it a custom to weld the bottom end or 6-o-clock by looking at it from the top. or do you move your head to look at it from the bottom?

[@kf8575]

Funny how the guy used to call himself "mr tig", yet could only weld flat on a bench 😄😄

[@forevermar7400]

Currently in welding school having a lot of trouble with this one theirs time my teacher has me redoing it

[@MegaBoilermaker]

Also structural steel tubing Bob.

[@herbender]

everytime i see a video on 6g certification weld it shows that the pipe ends are open, in my days they used to cover the ends so you could not look inside and see what you are doing which is most common when in the field or doing reparations to boilers and such, is this only common practice in Belgium?

[@edu6092]

Buen tutorial, gracias desde Perú.

[@talicia28]

thats great bro but thats good if your doing that then your feeding the wire from the top inside of the pipe. if you can do that you can weld almost anything and any size

[@shahlaaabd1220]

Why you didn’t made shielded from inside to avoid oxsiditon

[@danielainsworth4092]

i want to see bob moffatt do a 6g video using stick

[@JP-ku5ur]

great video!

[@weldingsolutions4264]

Awesome video

[@SupraSav]

Are those MIG tacks..

[@lablue350]

I have a question. What good is it to have a big gap like in this video vs having a tighter gap. Also is it better to have a landing on the bevel??. Thank you Mr tig

[@Welddotcom]

As explained in the beginning of the video, everybody has a preference of fit-up. I like to use the wide gap and root face to draw reinforcement to the inside of the pipe and weld faster. The much slower method would be feathered edges and a key-hole approach which I find harder to make a consistent bead with. The key-hole I usually do on stainless and nickel based allows. Feeding the wire from the outside of a bevel on the bottom of a pipe weld has never been fun for me if I want good reinforcement. Again, there are many options and variables to produce this weld. What are the end results / code specs? What does the procedure call for? These may determine or stipulate how it is to be welded. Let us know on the Weld.com forum! weld.com/index.php/Weekend-Warrior-Welding-Forum/categories.html

[@setsoldas5078]

Weld.com quero conhecer esta lente que é usada no seu canal,por sinal muito bom maravilhoso.estou com minha visão comprometida.

[@krs1732]

Weld.com will you please do a stainless 6g or even 5g? if not then can you at least describe the technique,fitup, heat, etc. how do you keyhole while walking the cup? isn't that something you freehand?

[@lascoob970]

KRS 1 no you can walk the cup to.... but keyhole a pipe is stupid. alot of time you have to feed the bead looking through the top of the gap. key holing will screw you in a pipe rack or heater... you simply can't do it. got to feed the wire through the gap . most pipe welding in the feild is done in extremely tight spots.

[@setsoldas5078]

Calm down there Kirk Cousins😂

[@rockdawg1467]

I think mr tig and bob moffet booth know their stuff this is a instructional video and they have a time frame to show everyone how a 6g weld is done like bob said there are three ways to weld a 6g pipe they cant be perfect all the time some times you make mistakes

What is the difference from the ER70-S6 and ER 70-S2?

[@thomasferguson6688]

“Mr. Tig” had to go get Bob Moffat to do some real tig welding.

[@TexasLeverGunner]

A lot of places still blind both ends of the pipe off. I guess it just depends on how critical the job is that they are hiring you for.

[@mikealmeida9006]

what is a lens that uses your camera to film the puddle?

How long till a video with 6010 root and 7018 fill and cap? It would be very helpful... Thanks

[@vicentediaz6491]

What is the brand or the filler rod used?

[@grndragon2443]

Is there a standard dimension(s) of pipe or is it per tester?

[@johnh2018]

It all depends who you are testing for. Ingels who is a ship building company tests on 5in schedule 40, NBS (National Boiler Sevices) tests on 2in heavy wall tube that must be tacked in a simulated fixture. Some pipeline companies will test between 6in and 24in piping. I hope this helps alittle.

[@grndragon2443]

yes, thank you for answering.
