Hello everyone.
Today, I recorded a video comparing the differences in welding current sizes when creating a large weld bead in T-joint welding.
What is the difference between welding multiple layers with low current and single layer welding with high current?
1. In terms of visual aspect, both produce good weld beads.
2. The work speed is faster when single-layer welding is performed with high current.
3. Weld bead color is better for low current welding.
4. When low heat input is desired, welding multiple layers with low current is better than welding with high current.
5. When the current is high, the heat input is high, but the welding heat distortion is surprisingly small. Even if welding is done with a low current and reduced heat input, welding distortion occurs more when multiple layers are welded.
There are pros and cons like these.
It will be helpful to refer to these contents when you need to TIG weld thick metal.
In the future, we will compare the differences in other situations.
Thank you for watching and have a great week.

여러분 안녕하세요.
오늘은 T-조인트 용접에서 큰 용접비드를 만들어야할때 용접전류 크기에 대한 차이점비교를 영상에 담았습니다.
낮은 전류로 여러층 용접할때와 높은 전류로 단층 용접 했을때 어떤 차이점이 있을까요?
1. 비주얼적인 부분에서는 둘다 좋은 용접비드가 만들어집니다.
2. 작업속도는 높은 전류로 단층 용접했을때가 더 빠릅니다.
3. 용접비드 색깔은 낮은 전류 용접이 더 좋습니다.
4. 낮은 열입력을 원할때에는 낮은 전류로 여러층 겹쳐서 용접하는 것이 높은 전류로 용접했을때 보다 더 좋습니다.
5. 높은 전류일때 열입력은 높지만 의외로 용접열 왜곡은 작습니다. 낮은 전류로 열입력을 줄여서 용접하더라도 여러층 겹쳐서 용접하면 용접왜곡이 더 많이 일어납니다.
이와 같은 장단점들이 있습니다.
두꺼운 금속을 TIG용접해야할때 이 내용들을 참고하시면 도움이 되실겁니다.
차후에는 다른 상황에서도 차이점을 비교해보도록 하겠습니다.
시청해주셔서 감사합니다 그리고 즐거운 한주 보내세요.

Интересно,а трубу получится сварить вторым способом? спасибо.
Your welding is absolutely excellent. Very good videos.
Джин,спасибо за подробный комментарий🤝
@@шурийсалатович7😮
Been welding for a decade, and it's still an absolute treat to watch you work. A true master at his craft 👌
Mastering knowledge of material chemistry and physics on books sometimes defeat long experience
@@teknosql4740nah not when your doing the actual work think about it
@@teknosql4740yah but can they make the weld lol
This is great information--often, hotter settings actually mean less heat input, less distortion, and less time into the finished product BUT read the WPS and see what is allowed BEFORE you set everything on kill. Cutting out good welds because you didn't follow the WPS makes for a long day.
This is interesting and impressive for a video but that's about it. There is a reason why many stainless procedures only allow for a few inches at a time. Creating a big puddle that looks like it is washed in at the edges doesn't mean the weld has penetrated properly. With the low slow method you get penetration across the entire weld. The hot and fast method the penetration is just down the middle. Not much different than running hardwire with a big puddle and without any movement.
Something this thick has to be beveled and filled in, you won't get penetration otherwise.
Longer time of weld is mor heat with sainless
The colder the weld makes for a stronger weld
@@christophermcgarry7451lol no
Just remember pro welders it's not about what he is welding for, it's about demonstrating teqnique and comparing high vs low amps. This isnt a guide to welding thick plate correctly.
Which is lost on practically everyone here.
I a hobbyist welder. Your welds are very pretty.
very informative, as a young welder that's still learning i thank you very much for all of this
Yeh I loved the part where he spoke on there too 😂
Alway a good demonstration and presentation .
Espectacular trabajo maestro, clase magistral como siempre, gracias por compartir sus conocimientos y experiencias, un saludo cordial y por supuesto un merecido like desde Narón (Galicia)👍🤓😜
Ótima demonstração.
Nada a favor ou contra, cada um dos métodos.
Apenas uma muito boa demostração das características de cada método.
Obrigado pela aula mestre.
without speaking telling everthing is this :) thanks so much I am the new one in tig welding. and I am learning from your videos...
The language of metal !
Seni öğretmenlikten sanayiye iten hayat bize neler yapmaz. Kaynakçılık hayatında başarılar dilerim.
Better off going to welding tips and tricks..
😂😂👍
Ive watch so many so called welding advice videos recently, with people using MMA doing a series of tacks. Then when i leave a comment, telling people that this is not how to do it. I then get reply comment telling me that i dont know what im talking about. It is nice to finally see a video with someone who knows what they are doing.
15 years as a food grade sanitary welder 065 stainless steel, purge weld, pipe fitter/ welder , nice welds , walking the coup takes time to Master.
“Stitching dimes”!
Pleasure to watch you work, Sir!
I could do it without riding the cup. He's cheating and scratching the metal
@@analogalbacore7166nobody gives a fuck as long as the weld is structural. why don’t you go try out for the olympics if you’re so good
High current tends to undercut more. On extremely thick steel that I weld in the oilfield, I run heavy hot passes for my fill to limit distortion and for speed, then cap the weld with a lower current setting to get that nice appearance.
I agree with you
Beautiful welding.
Sorry I don't speak finger 😂
Yea is it so hard to speak in a video
🖕 understand that? 🤨
😂😂😂😂😂😂😂😂😂😂😂
😂😂😂😂😂@@jessihawkins9116
@jessihawkins9116 No I do not understand that. In my country, 🖕 means thank you.
Awesome machine. Never seen one like that before
Looks like a Chinese copy of the Japanese OTC machine from the 90's
The best as alway’s. Thank you.
Thank for your trending job
Всё по факту. Хорошее видео показывающее плюсы и минусы .
... BRAVO ... YOU ARE AN EXAMPLE OF HOW YOU CAN SAID EVERYTHING WITHOUT USING THE BLA BLA ...
Could of done with a root run in the high amp run to ensure root penetration.
1 hot pass,Not the best throat from what I can see. 37/38yrs
can you show penetration by cutting the 2 welds in half?
This person is very expressive with their hands.
This is way beyond my welding skill. That 3 phase tig is crazy looking too. Thank you for your teaching I wish you use around 30A to 100A.
3 phase? 😕
@buildaboiworkshop but AC can be single or double too though 🤔
Génial. Soudage à courant élevé si le poste le permet
Merci
C'est de l'art. Magnifique
your the best
Thank you / terima kasih !👍👍
감사합니다
EXCELENTE MAESTRO!!!!!
Very useful 👌👌👌
beautiful welds
Excelente gostaria de soldar assim um dia
Your test is like comparing apples to oranges. You cannot compare high current to low current by using different diameter filler rods, due to the weld deposition rate will be considerably different. Your low current welds were made with a 2.4mm diameter filler rod and high current weld was with a 4mm diameter filler rod. Your low current setting was at 159 amps so would have been able to run the 4mm rod without any issues to achieve a higher deposition rate resulting with fewer passes resulting in less distortion. I challenge you to do this test again using only one size filler rod on both tests.
Welding with rubber gloves, especially gloves that have the potential to collect moisture on the top, is very dangerous sir. But good welding. :)
I love TIG WELDING ❤ and MIG too
You are pro!
Gorgeous work. I never seen welds this good looking.
Nice clear demostraion with no touch downs lol
well if you get the penetration and no shrinkage or tearing from the weld to the material with one pass then do it, as shown it is far quicker.
but not all thickness and types of stainless steel can benifit from it, as yours looks like its bin cut from flat sheet hot formed, so it means it is a softer stainless so you get less stress
well there is a fast amount of types from the metals used down to the procces of making it like cold formed to hot formed and treated to un treatred and so on
so do a weld test then cut through the weld and check to make sure all is good,
but for hobbyist well try and it and decide.
for the pro jobs, it comes down to the certification approval and after 30 years causious welding wins hands down as if you try to cut corners it allways bites you in the ass :)
@@RonanABR helium or pure argon give a cleaner weld at high temp it does not increase enough higher temperature for welding
At high amp of around 400 welding I use a mix of the two
To make sure no imperfections in the root and the main and cap
Because when you lay wekds on top of the previous one you get a gas and metal contamination which arises from the next weld if you don't have a good clean gas shield around the tungsten
As seen in the video all looks good but only a cut of the weld and atmomise test would clarify the contamination
I have to do such on aerospace products to get the certificate for the client
But anyway the guy is no amateur and does show he has a great skill
And would give him a 9/10
It's just nice to comment so others can get a better understanding how complicated it is to get a perfect weld that ticks all the boxes
@@RonanABR it's because he can lol
Anyway one should always have enough patience to perform a tidy weld
Regardless of it not being perfect or theirs no point welding as said before
If you rush or cut corners then your most likely spend time correcting
By any means I'm perfect but each time you weld then try to be
And I try to be or I would give up and go do another job lol
Oh I never mentioned why you should do a small weld first
It's because of the factor of the weld shinks
So if you lay a big weld in one go the pulling of the weld when cooling will pull the material massively
As can be seen in the video
As when he started the parts were level flush to the angle
And was not bad on the lower amp and more runs
But on the high amp at one run the material pulled /shunk so much it probably pulled by about 3 degrees
And you can see it rocking unevenly
So hence it bites you in the ass lol
And to say you can hear the weld fracturing/tearing as it cool under the stress
Thanks, guess I should have watched the whole video.
대단하십니다!!
Sou apaixonado pela TiG
YOU ARE AMAZING THANK YOU!!!
결국에는 히트 인풋이 디스토션을 결정하는건데 디스토션이 적은 쪽이 열입력이 적은 겁니다. 낮은 암페어의 멀티패스가 높은 암페어의 싱글패스보다 열입력 왜곡이 더 높죠. 대신 높은 암페어의 싱글패스는 필렛시엔 각목이 오목하게 나올 가능성이 있죠.

Отличное и познавательное пособие, спасибо!
1 artiste dans son domaine si seulement je pourrai êtres formé par 1 personnes comme ça je payerai le prix
Arigato godaimas .thanks for sharing your knowledge. I learned something new on every video you are one of my 5 favorite welders .
Korean, not Japanese. Use "gamsahabnida"
Alta frequência!!
Bardzo ładne spojenia.👌
а разрезать?? мне кажется оба способа не сварили сами листы.
похоже на "я тут пробую всякое и делюсь с вами"😛
ну да провара нет
Bravo !!!
뒷 테그가 없으면 여러번 용접한것이 식으면서 응축해서 쪼그라들었고
한번에 과대 각장을 만든용접은 크랙에 취약하여 쉽게 부러집니다.
4번 용접한것이 튼튼하고 크랙이 가지않습니다.
빽을 내지않는 부분은 과대전압을 사용하면 불량품이 됩니다.
빽을 내는곳에는 마음대로 과대전류로 용접해도 상관없습니다.
90도 각도에서 크랙발생이 당장은 나타나지 않지만
각도가 45도 40도에서는 크랙은 더 쉽게 발생됩니다.
Please what are the equipment you used🙏
Great !!
좋은걸 배우고 갑니다.
슬리브 두께가 하나는 10t고 하나는 2t라면 저리하면 안되겠죠
Thank you.MASTER.
Так почему же он на высоком токе сделал один проход? Да и еще другой рисунок использовал? Требую повторения эксперимента но с одинаковыми условиями.
Good job
Почему с обратной стороны не было прихваток???потомуи повело на длительной сварке
Problem is i have to play this song in me head to run these dam beautiful beads . Can we get this in a FreeBird or something ?
한국들어가면 찾아봽고 배우고싶네요..감사!
La presentación de la corriente baja quedó más bonita.
Пасиб за видео, интересно.
so what's best? low or high current? btw im new for tig welding..
그냥 현장에서 원하는 용접 해주면 됩니다!!
Outclassssss
NICE!
Mantap bang ❤❤❤
Hola buenos días

14 minutes later and i'm still unsure which one was better o.O
Я уж испугался, что он полностью заполнять уголок будет
Excuse me, how to record welding clearly ?
The high Heat looks beautiful but and the end of the day its all about your WPS. You weld outside that WPS and you and your inspector goes to war.
Unbelievable.
Sir how to weld aluminum from beginner
are we supposed to know what that sign language means? Why no words or cc? Is it so hard to explain? Is this asmr or something?
Not bas but your toes lines are patruding from the patent material, if you dont grind them in or stone flat MT (magnetic partical testing) your weld is going to be glowing. Not bad tho, all the swipming and back and forth would make me worry about lamination as well.
Cut and etch
Tip is out there a little far! Fyi move the tip into the cup a bit and you will not dip the pudd as often.
Третий слой можно делать уже в два прохода.

예술이네..

氬焊當co2 在用的，可以拿5支2mm的，超快但是會熱死😢
잘봤습니다
И в чем преимущество этой сварки перед MIG в данной ситуации? Столько времени потратить. По самому первому корневому шву понятно, что никакого проплаления кроме стенок там нет.
böyle kaynak yapmak hayalim
"Color" - это что за критерий оценки такой? Для каких-нибудь декоративных валиков такое может и ок , но в промышленной сварке - на кой? То же и с "heat input", нет предпочтения меньшего большему, или наоборот, есть металлургия сварочного шва с необходимым в данном конкретном случае heat input, при котором прочностные качества оптимально соотносятся с производительностью процесса.
Either current don't matter at least it wasn't a dribby drabby tacky weld that i usually get in my feeds 😂
Soldar un acero inoxidable con tanta corriente es un error. Hay que controlar el aporte térmico
👍👍👍👍👍
Is that stainless?
When you realize that technique is more important than the type.of gloves!😂😅😂😅😂😅😂😅😂😅😂😅😂😅😂😅😅😂😅😂😅😂😅
The guy shouts terribly when he says something 😅
It is not normal to weld thicknesses like that at the inside angle using TIG, this must be welded using MMA because this unnecessarily increases the HAZ, the groove obtained is not within the standards. This must be done in MMA, one pass at 2.5 and then at least 2 passes at 4 mm, in short, doing this with TIG is just fun, but not an industrial production approach.
Fucking gloves
You are the best
But
I think there is undercut and no crown in the fillet for the High current single pass. But nothing "must be done in MMA"......And the HAZ is well controlled in the video for both high and low current, probably less than MMA to achieve the same strength.
@@JamesZJi an MMA electrode of 4 this melts with in the 130 A, there in TIG it goes up to the 350A, in serious welding, there is even temperature control between passes, so as not to deteriorate the characteristics of the deposited metal, but also that of the base metal.
Good solutions for welding this kind of thing include MIG with gas-cored wire.
👍👍👍
