Big gap between pipes in TIG welding root pass 

Goodbye 2020 Bye Bye Bye virus Happy new year ;)

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.

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.

Thank you for sharing your skills. I didn't understand a word you said, but your video is self explanatory.

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.

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 .

여기는 한국채널이 아니고 글로벌채널임 한국사람은거의 없고 외국인들이 대부분임 실력도 좋고 설명은 더좋음 이걸로 대한민국도 알리고 진정한 애국자시네요 👍👍

Very impressive. I didn't even know it was possible to weld big gaps like this!

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。

As a beginner to welding, I find videos like this incredibly helpful. Great job! 안녕 from California.

Excellent video. Now I finally understand "crater once" that you use. I was trying to compare it to my machines 2T and 4T modes.

This gentleman is so far beyond mere “Excellence” it is incredible.

This is real world. You have to know how to handle big gaps as well as tight ones.

Смотрю ваши видео и учусь . Спасибо . Стал вашим подписчиком . Ещё раз спасибо

Thank you. Great english subtitles.

Молодец что ты делишься с полезным материалам 👍👍👍

отличное видео! Сам только начинаю и сразу такой бонус. Это 100% лайк

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.

Thanks!!!!!!! I wondered how to bridge such a huge gap. 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼

Bravo! Well done, you are the best welder and teacher even seen!

Muito bom amigo! Parabéns estou aprendendo com a solda tig, seus videos está me ajudando muito!

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?

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!

Вот вы китайцы такие маленькие а умные ну почти как мы ... 😀😀😀😀👍

Always a joy to watch . Happy New Year to all your end .

Le tue saldature sono uno spettacolo sei bravissimo

Great job

I didn't know i needed to watch this..but now i know I did.

하고지비님 뒷통수 댕!~~합니다 자막에 "펄스용접을 수동으로 한다고 생각 하시면" 진짜 멋진 스킬입니다 양쪽 끝스라에서 크레이터 전류로 융착시켜 열입력을 유지하는 역시 하고지비님 멋집니다 왕팬입니다

우리나라 용접사분들 기술력 세계최고 수준입니다. 외국인들이 볼때 불가능할꺼 같은데 용접으로 갭 몇센티 이상도 아무렇지 않게 때움.. 조선소에서 일했는데 용접 기술력은 최고수준입니다.

One of the very best welding channels! Every video is good.

Great man, best content, welder number 1.....🥇🤗

Спасибо большое, с наступающим новым годом

Я хоть и не сварщик, но думаю такой зазор недопустим!!!

NapakaGaling Mo.....!!!Lodi na kita

화가 밥아저씨가 생각나네요;; 참 쉽죠 ㅜㅜ

I'm a welder in training, thank you❤️ for your video, they are always easy to understand . Happy new year 🎉

太讚了!大師的【有】段功能四段次 控制入熱 循環編織 反覆的隕石坑真幽默! 配合上 影片中的 電流 手法 有基礎的焊工 就淺顯易操作!受益良多!

Como siempre Maestro perfecto Sus enseñanzas excelentes de gran ayuda Saludos Saludos desde México

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!

Great work wonderful video thanks best wishes everyone

아낌 없이 주는 나무 weld [HAGOJIBI]님 행복한 새해 되기를 바랍니다.

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!

You ser the Master welder

Nice video many thanks 👍

Спасибо вам огромное за информацию 🛠🛠🛠👍

Very well presented sir thank you, you are a superb instructor!

Korean and tig together in one video? ! Epic, my two favorite things to practice.

Me seeing the gap between the pipes in the thumbnail: “Definitely clickbait”. Hagojibi: “Hold my beer…” Me: Starts slow clap…

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.

Я как Наладчик - Ремонтник, Электро-сварочного и Газо - Плазмо-резательного Оборудования .... Отправляю этого китайца !!! В 5й класс взаимодействия эллектрики учить!!! И в 11.. Взаимодействие магнитных металлов и электрополя изучать.

didnt weld for 5 years but this was fun to watch

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.

素晴らしい技術！

Wow, you are seriously talented HAGOJIBI, awesome, instructional, inspirational videos always.

알고리즘으로 하고제바님 유튜브방송에 들어왔습니다. 용접을 배우고자 하고 관심있는분들에게 유익한 정보인것 같습니다. 갭 8mm~9mm 에서도 루트패스가 가능하다니 정말 실력자이십니다. 다른영상도 많이 많이 올려주세여 하고제비님 ^^!!

very useful lesson, I hope someone will employ me as a TIG welder one day ... :D

esta bien nada de exceso de penetración, ya que con esa abertura es fácil que se puede descolgar, eres un profesional de la soldadura.

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.

Очень доходчиво и по делу обьяснили. Класс 👍👍

Nice job my friend. 👍😉

прикольно, у меня приятель так же говорить начал когда провалился через крышу в стойло к быку))

Greetings from Los Angeles California 🇺🇸, great technique and skills. 😃😃😃 very well done Thanks

Happy new year seipai

Happy new year. Awesome vid. Hope more amazing videos to come.

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.

謝謝您 我是焊工 看你的視頻 感到幫助

Saludos desde argentina. Gracias.

넘잘하시네요큰도움돼었어요

Спасибо за информацию

Great , once again :) . Happy new year too

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

너무너무 알기쉽게잘설명해주셔서감사합니다

Good tutorial..HADEWAE SIA MAH

Классно! Не думал даже что так можно.

Как мне сказал один сварщик - если сварочная маска не пролазит, заварить можно! Я бы и обычными электррдами завалил такой стык

Trimakasih berbagi pengetahuannya👍 fans from indonesia

해외사이트에서 많이 보던 특수촬영 기법을 사용하시는 분을 국내에서도 만나게 도ㅣ어 너무 반갑습니다. 좋은 영상 앞으로 더 기대됩니다. 바로 추천 구독 눌렀습니다.

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.

Muito bom e eficiente muitíssimo obrigado pela ajuda 👍

좋은 영상 감사합니다... 하나 부탁좀 드려도 될까요? 쇳물에 따른 차이점을 잘 모르겠습니다.. 현재 학원에서 용접을 배우고 있고요... 쇳물의 농도에 따른 융착정도나 쇳물량에 따른 비드모양의 변화, 백 속살 파이널시 쇳물의 적정량에 대한 감을 아직 못잡고 있습니다.. 특히 파이널시 쇳물량을 제대로 조절못하고 잇습니다.. 영상보면서 연습하고 있는데도 잘안되네요... 가능하시다면 초보를 위해 영상으로 만들어주시면 참 고맙겠습니다...

nice videos... nice skill , nice edit , nice recording , nice explanation 👍👍👍

Gracias por compartir tus conocimientos. Saludos desde México.

I would like to see the 'wedding ring ' and xray !

i got that 65 dollars on hour job thx you so much even tho i dint understand a single word it was very informative

Best Channel! Great teacher! Thank you!

정말로 목소리,(알아듣기쉬운) 언어사용,설명하시는능력,영상,모두 다 최고중에도 최정상급이다!!!!!

gracias maestro.. muy bonito videos !

Feliz navidad excelente tu video

Merry critsmas and happy new year dear friend hago jibi

Great job!

Excelente !

Awesome video.. thanks for the subtitles... very informative... keep up the good work

Consulta la razon porque se deja tanta apertura aparte de entrar cin la buza es la dilatacion de la raiz al ser soldada y que no haya contraccion por tensiones remanentes causa de potencisles fisuraciones .

Great technique!...

배우고 싶습니다.

Спасибо тебе за науку!

Perfecto amigo,feliz año nuevo!

Thanks for the video

GREAT VIDEO!!!! Very explanatory and laid out very simply. I’m new to Tig welding and your videos help me learn much easier! 👍🏻👍🏻👍🏻👍🏻
