- Hello everyone.
Today I did "ROOT PASS" on a pipe with a wide gap.
This technique can be said to be the most basic content when TIG welding a large gap.
This method can be applied in various situations.
It can be applied in vertical welding, horizontal welding, overhead welding, and 5G position.
I'll show you those things later.
Thanks for watching.
Best wishes for a Happy New Year.

Bye Bye Bye virus
Happy new year ;)
Thank you for your precius lessons. I wish you happy New Year my master.
The welding boss all up in here:D
Thank you, I wish you that too.

As a retired welder, I watch a lot of videos for entertainment. I don't know which I am more impressed with, your welding skill, your explanation, or your camera work. Great job.
Is there a reason not to just cut a thin piece of pipe/material and make 2 welds? I'm curious in what kind of situation this type of weld would be the best solution?
@@pfistor the correct way would be to cut back and replace with a larger section that meets prober fit up. Not to cut a filler. Some places have tolerances for weld to weld spacing also
Experienced..
If i weld at the pace this guy is doing, i can go home at the end of the day.
Also the tagging with the plates is shit for the welder, tagg bullets or straight in the root.
His welding is fine but if i was his pipefitter i would start complaining he should go faster, got to make those meters!
@@aqaurius18 if you were his pipe fiter wuold you realy left gap so wide?
Step 1 fire the pipe fitter! Step 2 make sure the welding inspector doesn't see it step 3 pay off the xray tech in small non sequential bills.
Okay, that was a funny (but true) comment. :)
@I Am Sekou the pipes shouldn't have been that far apart in the first place so you need to fire the pipe fitter, and then I guess the xray tech is going to have to inspect that whole weld meticulously for fractures and cracks becuase of its size - UT testing like that is normally incredibly expensive
@I Am Sekou tom lowe is correct the pipe should be closer. I work in the oil and gas industry as an inspector we must visually inspect each weld and verify correct fitment and that the correct welding procedure is followed then sign off on the weld then x-ray follows and "shoots the weld " to verify that it is in spec typically 1104 welding code witch has a specific allowance for undercut ,porosity and alignment. After the x-ray film is developed you will see all the issues including the huge gap in parent materials that were filled in and the weld would require repairs or in this case cut out and welded correctly.
Having worked in underground utility construction it’s easy to compare to this conversation. This too is partly why I no longer work in that field. It’s so very typically American to point a finger and then short cut or shut down and wait, this is why projects run over time and over budget. The trades are supposed to have masters, journeyman and apprentices, yet the masters never behave like masters. I wonder how many guys can weld this gap and feel confident it’ll pass. The gentleman in this video seems to be, but he’s very obviously not American. Keep making jokes though. The more humans fail the more likely it is a robot will be made to take ur high prevailing wage jobs.
@@sputnikalgrim i was looking at it from the point of view in my narrow industry witch is tightly regulated. If a weld fails and me as the inspector let it go into service I could be held liable and face prison and monetary penalties. In other industries such as residential low pressure and food processing this technique is completely acceptable. Not Ideal but acceptable and he seems to be a very competent welder that many people could learn from . I'm sure I would enjoy seeing a master at his craft work and he would be an asset. I was not denigrating his skill.
I have worked in many other countries and seen less than adequate work. Its not only in the US that bad craftsman turn out crap work . So grow up every country has its good and bad . Its nice to be under budget and on time but not at the sacrifice of life and the environment.
Thank you for sharing your skills. I didn't understand a word you said, but your video is self explanatory.
@Domagoj Rubil for real I literally was watching with subtitles the whole time saw this comment and was like how tf did you not read that in plain English lol
Jajaj te mataste wey
If you didn't noticed, captions are there
I've attended a welding course and just finished with a work like this . What you show in the video is awesome and not so simple as one may think... thanks a lot for your explanations .
Do not do this to your welds. It's called "slugging a weld" & from a NDT prospective it is the quickest way to fail a final weld inspection if caught. It makes the root weak and you won't achieve a sound weld slugging it.
@@tonyconrad2895 at what point did he slug the weld?
i hope your not talking about his filler rod
Yes. Adding filler rod in the gap to close the root opening is slugging the weld. I was level NDT in Naval ship repair. I military standards & the same aviation, slugging is automatic rejection. The same goes for commercial diver, which I did for a couple of years.
@@tonyconrad2895 dude thats how you TIG weld thats like calling the wire coming out of a wire feed gun slugging i dont think you are any kind of welder if you dont even know what a TIG filler rod is
이분 나라에서 상줘야됩니다 .
지방에서 이렇게 디테일한 양질의 교육을 영상으로 남아 볼수있는게 얼마나 큰 행복인지 모릅니다 감사합니다 .
우리 나라 산업 발전에 크게 기여하고 계시다고 믿어 의심치 않습니다.
This gentleman is so far beyond mere “Excellence” it is incredible.
incredible useless why he use TIG for steel? why not MAG, why he leave so big gap? 2-3 mm is more than enough
@@tsugumorihoney2288 maybe you should learn something about welding.. refineries worldwide that have any type of good name require tig on 3/4 if not all pipe that is coming into a plant
Very impressive. I didn't even know it was possible to weld big gaps like this!
As a beginner to welding, I find videos like this incredibly helpful. Great job! 안녕 from California.
여기는 한국채널이 아니고 글로벌채널임 한국사람은거의 없고 외국인들이 대부분임 실력도 좋고 설명은 더좋음 이걸로 대한민국도 알리고 진정한 애국자시네요 👍👍
Excellent video. Now I finally understand "crater once" that you use. I was trying to compare it to my machines 2T and 4T modes.
日本の溶接工を目指す学生です。
とても分かりやすくて、字幕もつけてくださって、今までで1番見やすい溶接動画です👍😍
この動画を見て精進いたします。
This is real world. You have to know how to handle big gaps as well as tight ones.
Hahaha love this comment
I am a retired Journeyman Welder who also had a B Pressure ticket for pressure piping systems. I can honestly say that if anyone had been caught doing a joint like this they would have been run off no questions asked. This way of doing things would take far too long, use too much material and gas, and warp all the hell due to cooling with a slow process. When using TIG on pipe you frequently have to gap the top of the pipe wider than the bottom so that as you progress the gap will shrink as the weld cools and brings it back into tolerance. The normal way of doing this kind of work requires a set up 60 degree included angle vee preparation and the gap should be about 1 to 1 1/2 times the diameter of the filler rod with no land (sometimes called a feather edge). When you come off bottom you feed the rod through the gap so that it is inside the pipe to mitigate gravity. As you proceed up the side you change from inside the pipe to outside the pipe. There is no weaving of any kind and when you are done you should have a bead on the inside that resembles a wedding ring. Once your root is in you can run your hot pass, fill, and cap using a walking the cup method as shown here or if you are steady enough you can free hand it.
I saw one comment that put it succinctly. Its a demonstration, not an endorsement. Its just showing what can be done, not necessarily in a pipefitting situation, but in a personal use or home repair situation.
Молодец что ты делишься с полезным материалам 👍👍👍
Смотрю ваши видео и учусь . Спасибо . Стал вашим подписчиком . Ещё раз спасибо
Bravo! Well done, you are the best welder and teacher even seen!
Thank you. Great english subtitles.
Yes
отличное видео!
Сам только начинаю и сразу такой бонус.
Это 100% лайк
Im a pipe fitter and i would never give my welder a gap like that....for one i would be embarrassed and for two all the welders that iv ever worked with would “politely” tell me to fix it!
The usual pipe fitter term of “a good welder would catch that!”, really does apply here🤣
Saying that, i could use this video the next time my welder says the gap is half a mil to wide!
Thanks!!!!!!! I wondered how to bridge such a huge gap. 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼
Le tue saldature sono uno spettacolo sei bravissimo
Вот вы китайцы такие маленькие а умные ну почти как мы ...

Почти не считаеться😂
우리나라 용접사분들 기술력 세계최고 수준입니다. 외국인들이 볼때 불가능할꺼 같은데 용접으로 갭 몇센티 이상도 아무렇지 않게 때움.. 조선소에서 일했는데 용접 기술력은 최고수준입니다.
Я хоть и не сварщик, но думаю такой зазор недопустим!!!
Always a joy to watch . Happy New Year to all your end .
Thank you for a slow and patient explanation. My thought is that it did not seem like much penetration into the pipe metal. Also, I wonder if the irregularity on the inside can cause erosion by the material in the pipe, through turbulence?

참 쉽죠 ㅜㅜ
素晴らしい技術！
Korean and tig together in one video? ! Epic, my two favorite things to practice.
Great man, best content, welder number 1.....🥇🤗
Muito bom amigo! Parabéns estou aprendendo com a solda tig, seus videos está me ajudando muito!
Great job

I rarely watch subtitled videos like this (i like to listen while I do other stuff and just glance at the video), but I followed this one all the way through. Amazon work and subscribing for sure now!
Спасибо за информацию
아낌 없이 주는 나무 weld [HAGOJIBI]님 행복한 새해 되기를 바랍니다.
I'm a welder in training, thank you❤️ for your video, they are always easy to understand . Happy new year 🎉
U speak Chinese?

Hi!
Man you make me envy you when I see youre welding skills. It's a pleasure watching you welding. I hope buying a TIG welding machine in 2021.
Have a happy new year!
I'm also buying my first TIG this year. I hope one day to be at least half as good as this. Happy new year.
Como siempre Maestro perfecto
Sus enseñanzas excelentes de gran ayuda Saludos

Me seeing the gap between the pipes in the thumbnail: “Definitely clickbait”.
Hagojibi: “Hold my beer…”
Me: Starts slow clap…
That's exactly what happened...
Как мне сказал один сварщик - если сварочная маска не пролазит, заварить можно!
Я бы и обычными электррдами завалил такой стык
간단한 용접 방식 감사합니다,
You ser the Master welder
Nice job my friend. 👍😉
very useful lesson, I hope someone will employ me as a TIG welder one day ... :D
Happy new year seipai
didnt weld for 5 years but this was fun to watch
넘잘하시네요큰도움돼었어요
Спасибо вам огромное за информацию 🛠🛠🛠👍
esta bien nada de exceso de penetración, ya que con esa abertura es fácil que se puede descolgar, eres un profesional de la soldadura.
Nice video many thanks 👍
Nice video.
They explained and showed it great.
Welding a wide gap also takes a little practice. Because the seam can collapse very quickly.
I'm looking forward to the sequel.

hello, im a german industrial mechanic. in my apprenticeship we learned welding, although not as good as real welder, but we had the
opportunity to participate in a welding contest. this was only an experiment, it would have been great to see how you finish the weld.
cause like this it unfortunately has no strength. basically you closed the gap by melting the rods. but you need to melt the pipes,
and make a combination with the rod, so it form a bond. this thick pipe has to be welded in multiple layers, and there is plenty of
techniques you can use. if im totally talking shit, pls let me know. but at least that is how i learned it during my time at the company.
화질이 엄청 좋아지셨네요 ㅋㅋㅋ 너무 좋습니다
I had to use tig pulse for these tiny little gear boxes. Had to weld these little gears on small shaft maybe 3mm wide. Also had to use feeler gauges to set the gear within a few thousands as I welded the gear on. When grounding the gear box, you couldn't put the grounding on the opposite shafts, because it could arc out internally. Basically these things were a nightmare to weld, and at $500 per gear box, messing up wasn't an option. The gearboxes were used to open and close valves for natural gas pipe lines under water if I remembered correctly.
Very well presented sir thank you, you are a superb instructor!
Great , once again :) . Happy new year too
너무너무 알기쉽게잘설명해주셔서감사합니다
배우고 싶습니다.
알고리즘으로 하고제바님 유튜브방송에 들어왔습니다.
용접을 배우고자 하고 관심있는분들에게 유익한 정보인것 같습니다.
갭 8mm~9mm 에서도 루트패스가 가능하다니 정말 실력자이십니다. 다른영상도 많이 많이 올려주세여 하고제비님 ^^!!
Очень доходчиво и по делу обьяснили. Класс 👍👍
Классно! Не думал даже что так можно.
謝謝您
我是焊工
看你的視頻
感到幫助
I'm an API inspector in oil refineries and chemical plants all over North America. That's a rejected weld every time. It would be cut out, refit, and rewelded. That's an abysmal welding "technique" that shouldn't be taught.
Inspector not actual welder makes since you know nothing but what we are suppose to do lol
@@christopherkicklighter1329 Clearly I know more about it than you. I welded for quite a few year before moving up to Inspections. As a welder, I wouldn't have even tacked up such a poorly fit pipe because I knew it was rejectable then. There is no point in busting a weld due to a bad fit.
@@atheistontheroad4545 maybe so then you know there are times that the situation you are in can not be helped and you have to make it work.
@@christopherkicklighter1329 No, I know the exact opposite. Poor welding technique is not a fix for poor fitting technique.
Looks like we will just have to agree to disagree
Greetings from Los Angeles California 🇺🇸, great technique and skills. 😃😃😃 very well done Thanks
Wow, you are seriously talented HAGOJIBI, awesome, instructional, inspirational videos always.
I would like to see the 'wedding ring ' and xray !
прикольно, у меня приятель так же говорить начал когда провалился через крышу в стойло к быку))
Great work wonderful video thanks best wishes everyone
Great job!
Excelente !
Very good video. I will put this to use. Thank you for detailed explanation. I’m just starting out so this was very helpful. Thank you.
Thank you.MASTER
Perfect
감사합니다.
Happy new year. Awesome vid. Hope more amazing videos to come.
i got that 65 dollars on hour job thx you so much even tho i dint understand a single word it was very informative
GREAT VIDEO!!!! Very explanatory and laid out very simply. I’m new to Tig welding and your videos help me learn much easier! 👍🏻👍🏻👍🏻👍🏻
Perfect 👌
Спасибо тебе за науку!
Perfecto amigo,feliz año nuevo!
Tig looks easy compared to mig. Can’t believe you can actually see that well while tig welding
새해복 많이 받으세요
항상 퀄리티 좋은 영상 감사합니다. 용접 배우면서 시작한지 얼마 안되서 시력이 너무 안 좋아지는 관계로 지금은 그만두었지만 그래도 계속 보게되네요. 항상 기술에 감탄하며 많이 배워갑니다.
Dobra technika pozdrawiam
Vary impressive tig welding to all the people that gave it a thumbs down or bad comment you don't know a good welder or even a good weld from a bad one so take your opinions elsewhere because you shouldn't be watching videos like this
Best Channel!
Great teacher! Thank you!
Welding is one of those things you watch and think "that's easy." You think that until you strike your first arc 😂. I recall my first weld, stick welding 25 years ago 😂😂. I won't tell you that story, even my grandkids don't know that one 😂.
Saludos desde argentina. Gracias.
Thanks for the video
That Korean can weld!!!!! Well done brother
Good sir thank you sir
Merry critsmas and happy new year dear friend hago jibi
