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. 용접기 및 주변기기에 대한 내용은 제조사에 문의 하시면 더 정확한 답변을 얻으실수 있습니다. ↓↓↓↓↓↓↓ korea@nswel.com 내쇼날시스템 대표전화 051-941-9701~2
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.
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.
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.
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)👍🤓😜
Go to school to learn to weld because laying down a colorfull weld bead doesn't mean it's a good weld with adequate root penetration that will pass an AWS certification
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.
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.
Your deposition rate should be changing if you are welding at a very different current, this is normal and is part of the difference being demonstrated. To be honest I'm not a fan of these 0% penetration "pretty" welding techniques, so I wouldn't be doing either unless it was just decorative or needed to be cut away later.
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.
I would probably do a single root pass at high current and the cap it with a second pass at lower current. The high current pass appears to maybe be undercut where it ties in to the plates. But the real issue here for allot of welders is with the current. 330+ Amps is more than out of reach for allot of welding rigs. Further you need a larger water cooled torch setup as well. Most of the torches I see are 250A and when pushed can actually burn up the wire in the hose. Go ahead and ask me why I know this! So unless you have a supply like say a Miller Dynasty 700 and a 400Amp torch kit you are gonna be using low current. This guy is a kick ass welder though.
@@CesarB794 Most welders in most shops are gonna be 300Amps or less. They tend to fall down when pushed to their limits or trip the feed breaker. Power supplies capable of more are expensive and require serious infrastructure to make use of their capabilities. Furthermore, single pass welding of thick sections produces poorer results than root, fill, and cap passes. In the end a large power supply is likely not necessary for most shops. The shop I worked for we had a 650ADC CC/CV miller supply. We used it very little. The miller syncrowave 300A satutated core supplies were used every day and seldom at more than 200Amps.
@@mikeiver Oooh I would love a supply like that, I used to use a dynasty 350 and would often max that out for thick ali stuff. I calculated that 30% of the power was going into the watercooled cable lol, but it still had enough grunt to hold max current. Loved those nice simple Millers, and they would let you get real silly with the waveform if you wanted to.
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.
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.
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
не везде можно использовать большие токи, тем более на нержавеющих сталях возможны горячие трещины, потому смотрите в конструкторскую документацию и рекомендации по режимах сварки

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

I a hobbyist welder. Your welds are very pretty.
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.
can you show penetration by cutting the 2 welds in half?
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
very informative, as a young welder that's still learning i thank you very much for all of this

Sir how to weld aluminum from beginner

Excelente gostaria de soldar assim um dia
Почему с обратной стороны не было прихваток???потомуи повело на длительной сварке
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.

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.

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.
