Inconel is nothing to mess around with, but you make it look so easy like its carbon steel. Nice brother

[@Ray-xv7rh]

Turbine welder here guys... 90's old scool.. So many tryed ro shut me up... But im.still here.... Purge your iner pipe.guys... Root run is the best .. ;) Love from the UK .. :)

[@zacariasrojo1126]

Why do you tape all the holesbbn on that pipe?

[@johnbrennan4759]

In the UK we use argon with 2.5 or 5.0% hydrogen when welding inconel it gives a much clearer pool

[@MRTYREMULISHA]

Nice video and arc shots guys,makes a huge difference to be able to see the hole weld from start to finish!!

[@flatwater5]

Abraham, you are one smooth operator. All respect, Sir.

[@Portarius1984]

I love the tight looking beads. Sometimes the cat paws don't look right in a horizontal or 6 g pass. I love free hand as a boilermaker, in fact many of us can't walk the cup.

[@manos3790]

Freehand quantifies you as a partial welding genius. Walking the cup is supposedly less skilful? I know of certain pharmaceutical manufacturers in the UK that do not allow it during tests.

[@kf8575]

@@manos3790 Dairy too, also when using a trailing shield if welding titanium, welding aluminium. Have worked for a few in the UK that wouldnt have it if you started walking the dog lol

[@rolltide2937]

Great job the other two "drip" and "keyhole" techniques also works good if you are doing it on the actual inconel base material or any other super high chromium base metal. You guys should do a video on the metal characteristics of each base material and the technique best used for that material!!!!!! Great job guys keep it up!!!! It's great to see real welders on KZbin!!!!!!!

[@rolltide2937]

WeldTube you guys are doing a awesome job passing down our craft to others. I'm a second generation pipe welder and welding is the only type of work I've done my whole life. I've been a welding instructor for many of those years and teaching others is what I love to do, in my classes I teach the four root pass techniques "face feeding ,backfeeding, dripping and keyhole knowing all of them will give you the ability to weld any type of open butt weld on any base material. You guys are doing a excellent job on your demonstrations . You guys should also show how to repair internal root defects like rod chop & incomplete wall fusion by pulling it back with your tig rig or using a "Magic Wand" !!! I teach guys those techniques because not ever time are you gonna put it in perfect and if you do have a defect you need to know how to fix it!!!!!!!! Good luck man keep these great videos coming you are helping guys all over the world become better hands!!!! A student can only go as far as the instruction that's given to him/her!!!!!

[@krs1732]

What is it when your "dripping" your root pass?

[@rolltide2937]

KRS 1 when using the drip technique you place the tig wire on the edge of the bevel at the same time you point the tungsten towards the bevel. You melt away the bevel and deposit a small amount of filler material then move to the other side of the bevel and continue the same motion. This method works great on base metals that have different melting points than the filler wire. Nickel and chromium base metals are harder to weld because the filler melts before the wall of the bevel is broken down by melting the bevel wall first you’ll have less likelihood of incomplete wall fusion.

[@krs1732]

Is there a video showing how to do this? Kind of hard to visualize what you wrote.What I don't get is what you said about melting the bevel and depositing a small amount of filler and then move to the other side of the bevel. Do you mean you do the same thing to the other bevel by melting it also and depositing filler? You go bevel to bevel while adding filler to each side? If that the case how wide is the gap?

[@rolltide2937]

KRS 1 I use a 5/32 gap but depending on the size of pipe some guys use a 3/16 gap because most alloy pipe will draw and the gap will close up. Most high nickel or stainless steel wire have a fast freeze characteristic so the puddle solidifies immediately once you move to the opposite bevel edge. Also when useing bigger gaps it helps if you use a high level of purge gas pressure the internal pressure helps cool off the puddle as you deposit the root pass, that high pressure also keeps you from dripping to much metal causing excessive root penetration ,to much gas will blow your arc away but just high enough to keep the root from falling in causing a heavy drip. I haven’t seen a video demonstration of dripping on KZbin but mabe these guys will make one. It will benefit you as a professional welder to learn all the root pass techniques back feeding works great most of the time but sometimes depending on the metal dripping works 100% better.

[@Josemendoza-mf6ot]

Good welder ..thank you for your time and video..

[@andykosh4402]

Very coolLove the videos from you guysKeep them coming

[@davidmeeks8176]

Great job! Could you make a video for the 309L tig and stick test? That rod has been kicking my butt for ever. It's the dissimilar metals test. 2" double extra heavy coupon, 309L tig root and hot pass; then 309L stick out. Thanks.

[@cristianortiz1675]

Cold wire on 7:40 it’s scary to see so much reinforcement don’t know if this is calling for the 1/8 limit but I prefer to keyhole and dip to keep a flat root inside the Pipe

[@royhopkins2906]

Will one of y'all do a inconel stick weld on pipe?

[@rj10ramirez]

So I’m guessing you can’t double wire the fill passes? Not fully sure how all that works so I’m just wondering. Couldn’t you use double wire to fill or no?

[@johnbrennan203]

What shielding gas are you using?in the UK we would use Argon 2.5% or 5% Hydrogen it gives a more fluid cleaner weld pool

[@tankerpure91]

How long did they take from start to finish?

[@michaelcostello6991]

Thank you very much for this demonstration.

[@TheGmanamaya]

What a beast... "I like to FEED" keep on eating them welds and getting paid boy!

[@shawndrennen8092]

Wow. It’s amazing how cold you guys run your roots. I’m running 1 3/4” tubes at 125 amps on carbon tubes. On 2” tubes I run my root at 130-140.

[@DerrickFishes]

With no landing?

[@shawndrennen8092]

@@DerrickFishes yes

[@irocprod10]

will my roots come out just as good if im feeding the filler from the side? im no good feeding from the top

[@txdocprich_8404]

Learn that left hand for the right side and you won’t be so contorted bro. Very nice job, inconel can be a pain!

[@chrisplayz253]

Is this inconel material, or just carbon with inconel filler?

[@thomasmcnicholas8656]

Abraham you guys get into any Hastelloy Tig ?? Been doing some 1” lately and talk about a dirty puddle....... great work here too !!👍

[@austinwilson4440]

Was always taught to leave the stops in a line because of dry leads the end is ground down

[@panzerfaust7672]

This youtube channel is the shit bro, Hjalmar and you always come with solid content that isn't available on this site. Duplex next?

[@tanataotengahere5978]

Nice mahi, an vid.. awesome even.. kaapai..Kia ora👍

[@HamRadio200]

what benefit would this have being tig welded vs stick welded? Seems like alot of time to do this tig and much less with stick.

[@kelvinsudds878]

Tig welding naturally has less impurities than stick and A LOT CLEANER, more consistent and on average a much stronger weld than the stick or mig processes because of the lack of perosity, slag-inclusions, undercut and shi like that.

[@azogdefiler55]

This guy got some real skils , nice lole

[@2759591]

Beautiful, how long did it take to weld that coupon?

[@williamarnett3234]

Don’t know where been working bro, but damned if my fitter gonna set there and hold that while u build a bridge. Lol 😊

[@HamRadio200]

What amazes me is how much angle he as on the torch. if you watch other videos, especially when welding flat stuff, the angle is 10-20degrees. this angle here looks way more than that..

[@jaquelmcintosh8896]

Welding at a flatter angle is a way to control heat, particularly with sanitary thin wall tube

[@chrisjones6165]

My question is on how to move the torch on pipe? I can't seem to maintain my angle as I curve around pipe. Don't have problem on plate but do on pipe.. starting class tomorrow for 6g Tig cert got asme ix for smaw last qtr but I'm really struggling on Tig pipe with the curve of pipe, gets real bad on walking the cup.

[@drums2god]

What size tungsten are you running? For that heavy of a pipe I’d imagine 1/8 or bigger? I used to always run 3/32 until recently when I tried another guys set up and actually saw how much nicer 1/8 runs at higher amps.

[@kf8575]

Size of tungsten isnt anything to do with thickness of pipe dude, its related to amperage👍

[@HamRadio200]

I noticed he put the tacks at the 3 and 9 o'clock position. could he rotate it and put the tacks at the 12 and 6 o'clock position and still achieve the same results?

[@morganweller1491]

Crazy the puddle looks dirty ASF never welded inconel would love to try it out looks hard though the puddle looks watery asf

Parabéns, só uma dúvida vc fez a raiz com a vareta com 2,5 ou com 1/8

[@patrickfarley8036]

How long did it take to finish in real time and how many passes and rods of filler did you use? Some patients bro! Looks great!

[@danielhunsel7830]

What lens are you using?

[@jwayfan]

where did you get the hood? also why the end not caped if you are purging??????

[@rdaugherty52]

Thanks for showing this blows my mind I could weld carbon steel pipe like this with stick or mig but tig no way just curious if you went out and welded this for a nuclear plant how much would you charge I know it shouldn't be cheap.

[@jonathonsherwood741]

What temp you rubbing on?

[@pinoymetal]

Sir why you’re put tape what’s the purpose?

[@adonisx-.-.790]

Do you always keep the rod focused on the top bevel on both sides when doing the root pass?

[@luisrodriguez7470]

Tacking with a purge is the best way no or just point your torch sideways ...and use heat tape or aluminum tape .

[@slasrey88]

hye bro i have a question, what is the different between inconel 625 and 82 bro? last time i weld on inconel 625

[@johnjacobjingle8302]

The simple answer is chemistry and mechanical properties.. 82 has a tensile strenght of 80k, while 625 has one around 110k.. 82 flows like mud and has a sluggish dirty puddle.. the 82 has a much higher nickel content wich requires more energy to run the puddle..(this doesnt mean more amps) just needs more time for the base metal to heat up before it flows..

[@slasrey88]

Owh i see thanks for replying me bro

[@unatios2]

Do you guys ever use a 26 size torch? What applications is it used for?

[@jesseenriquez3400]

How long does it take to do the whole entire thing???

[@cleiderism]

Hey Abraham I was wondering... Don’t you have to keyhole inconel on the root? Or does it just depend on the filler and base metal???... looks like carbon pipe(dissimilar metal welding) very good amigo!!!!

[@adamgreenlee6361]

No keyhole needed on inco, back feed with good gap low heat..

[@peerez3146]

Stainless and inconel are not the same techniques and the same temperatures?

Please do a 7018 weave cap... lots of times in the field they want it done fast and stringers just take to long. So can we please get a weave thanks

[@chrisjones6165]

kyle boylan u wouldn't weave a 7018 in 6g because there would be a high chance of slag inclsions/perosity that is why stringers are used on 6g.

[@krs1732]

Right before you cap, I'm guessing you let it cool off so you can get the gold look right? Do you also let it cool after each cap pass before doing the next or just go straight to the next one and just finish all the cap beads?

That was beautifully done, and at 13:00 was your tungsten cracked? If so props brother props

[@shitsngiggles8371]

That gas lense on your purge hose is not doing you any good if you don't clog up the Collette hole on the front side cause all the gas is just running out of the hole and not coming out of the lense like you want it too.

Question? I'm in school now for welding.. working on 6g Tig carbon and am struggling with establishing the puddle and filler with out drowning tungsten.. ask for help and get told keep practicing.. is this an issue with my school or the normal of practice till u get it?

[@willc3586]

chris jones start heating the wall or bevel with the tungsten first, when you see the metal starting to liquefy start adding metal with your wire and ease it down into the bevel. Just remember be gentle when your TIG welding you don't have to force it or put a lot of pressure on the rig or the feed wire. The more relaxed you are while you're doing it including body position the better off you will be.

[@chrisjones6165]

Will Croom thanks I'll definitely give that a shot. Stick weld at work all day now and so used to pushing for the 6010

you guys are awesome but man I've never seen a wps that allowed a 3/16 gap. is that common down south?

[@hillbullymetal-5455]

Up north they like to keep the max gap allowance at 1/8” they give you 5/32 if your lucky I always get the biggest I can get gotta get that wire in there and I don’t like putting a bead in with 3/32” wire it’s nonsense

[@hillbullymetal-5455]

Lol I hear that bro good videos keep up the good work I like your guys channel I’ve learned a lot already well done

[@eridu77]

Great work, clear video, and on point instruction. I have a question about that silicon you mentioned. I've never welded Income but I don't think the Si is coming from the filler but maybe the Carbon Steel coupon? In the UA we take the cheap route at our school and do a bimetal test. Also as an instructor I should mention the gas lens for your purge line is a great idea, but if you leave the collet body empty the gas doesn't flow thru the lens. I take a filler rod of the same diameter and jam it in there with the ID end. Again great job.

[@houstonbigfooter]

Run one of them monsters with stick.

[@eljockvis]

can you show a cunifer test

[@jasonburris3557]

he should have let that cool down some before doing the cap you can see all the beads are sagging towards the bottom where the pipe was too hot there's a lot of tests you would bust for letting that happen also all the inconel have ever welded on still has that gold color but it doesn't run the way his did the ink and L always worked on was 4 in thick and you would have to add a shitload of filler wire to run a very short bead end up using an entire stick for 8 in worth of weld if that much
