TIG welding (comparison of tungsten angle and welding)

TIG welding (comparison of tungsten angle and welding)


Comparison of tungsten angles and welding Hello. Today… I made a video about “Comparison of Tungsten angle and Welding.” I’d appreciate it if you could press “subscribe” and “like.” Some people are curious about how to polish tungsten, so I made a video. If you’re looking for a book on welding or any material on welding… You can easily find the “Arc Difference” and the “Differences in Penetration” depending on the tungsten angle. And when they’re actually welded, I’m going to experiment with the connection. Let’s start with “spot welding.” Welding setup is set to “spot welding”. The current is 250 amps. Tungsten is about 10mm long. If we set it up like this, we can weld it… I thought I could see the momentary difference between the high currents and the arcs, so I set it up like this. If you look over there, it says 15 ?, 30 ?, 60 ?. Those numbers are just for comparing tungsten angles to each other. It is not the exact angle, so please refer to it. So we tested three different types of tungsten with a spot weld. If you compare these three welds, there’s probably a fine difference between the size of the arc and the depth of the penetration. But when you look at the welds with your eyes, they’re almost indistinguishable. As a result… it doesn’t make much difference with “spot welding,” does it? Now, let’s compare the differences when we do a “straight weld” using a low current. I’ve actually done a short weld with a low current that feels like it’s actually going to be a short weld. We didn’t put this on camera either, but the arc has a slightly different shape. But when you look at the results, there’s a similar outcome that’s hard to tell. If you look over there, the size of the weld is slightly different from the size of the 15 ? and the 60 ?. But because I adjusted the speed with my hands, I don’t think the difference in the angle is necessarily the only difference. So I’m going to do an experiment on the turntable to make it more fair. In this experiment, the length and current of tungsten and the speed of the turntable are set to the same… I’m going to experiment with different angles of tungsten. We’ll start with “60 ? Tungsten.” Again, numbers are written to separate the angles. It’s not exactly the angle. Please refer to the benefits. I’ll do the experiment under these conditions. That would be a fairer review, wouldn’t it? The current is 120 amps. Tungsten is about 7mm long. The nozzle has an internal diameter of 16mm. No weld rods. Welded using “weld without a welding rod.” As with the “free-charging welding,” the tip of the tungsten was welded as close as possible to the weld pool. This is the result. And I prepared the same size for the pipe. The length and thickness of the pipe are all in the same size. The pipe cut surface was also machined with a fanometer. Then all three conditions will be the same, right? This time, we’ll test it at 30 degrees. Tungsten is about 7mm long. I’ll test it with the same conditions as before. So here’s what we’re going to do: compare it to the previous welds. Based on the color of the weld, there seems to be a slight difference in the heat input. This time, I will test it at 15 ? for the last time. Again, tungsten is about 7mm long. The current is 120 amps. And the rest of the conditions were tested with the same conditions as before. Again, compared with only the color of the weld, there seems to be a slight difference in the heat input. If you’re welding on the same condition, the difference in heat input means that the depth of penetration is also different. Let’s compare the three arcs. The camera was stupid, so I couldn’t get the exact shape of the arc in the video. But the arc is slightly different in shape. And compare the arc in “Crater Current.” So here’s the result. If you compare the colours of the welds… Based on the color of the weld, the heat level… There’s a very small difference. So today we’re going to test how these different tungsten angles actually relate to welding, and what’s the difference? Obviously, depending on the tungsten angle, the arc shape is slightly different. But if you look at the differences in today’s results, you can see… There’s a very small difference when you look at the weld results with your eyes only. But there’s a similar outcome that’s hard to tell. And I think it’s very close to the tip of the tungsten and the melting pool when you’re welding on a “weld without a welding rod.” So I don’t think there’s much difference between the welds. As you can see, “Width of welds” is pretty much the same. In today’s experiment, we did an experiment on how tungsten angles actually differ from welds and how they relate. As you can see in the video, there’s no big difference. But I think it was a very interesting experiment. And if you have a chance later, if you have a chance to do something like “back bead welding,” “walking the Cup,” “fillet welding,” “freehand welding,” it’s going to be a very interesting experiment. Now, if you could sum up what we’re talking about today… Depending on the angle of tungsten, the arc varies in shape. But the difference is very small. And judging by the color of the weld, the heat level… high angle tungsten You can see that the heat in “60 ? Tungsten” is slightly higher. But it’s also very small. And in welding, where the tip of tungsten, such as “spot welding” or “weld without filler,” is very close to the melting pool… I can’t find much difference. So in the future, we’re going to experiment with what’s different about “back bead welding,” “walking the Cup,” fillet welding, freehand welding. So you can learn a little more about how to polish tungsten in some situations. I didn’t find this cool-down result today, but I did some interesting experiments. I’ll come back with a more interesting video next time. Thanks for watching.

  1. Thank you sir.
    Anyone needing English translation.. click on 3dots above video, click captions, then choose English. Subtitles will now be present.

  2. Excelente manera de experimentar. Gracias por el video y te has ganado un nuevo suscriptor. Saludos desde Ecuador 👍😎

  3. Ya encontré la forma de traducir al español grasias nunca e soldado con tig podrías alludarme a como ajustar mi máquina inverter 225amp.para empesar con acero y aluminio gracias

  4. 서스스케쥴 10짜리를 2.4갭이나 2 파이 정도로만 벌리고 빽내는 법도 궁금해요 오바헤드에서도 가능 한가 궁금하네요
    보통 턴테이블 사용하는곳은 12시방향에서 하진용접으로 10짜리 파이프를 2.4나2파이로 갭을 줘서 용접을 하던대 빽을 내는 방법 자세하게 가르쳐주시면 정말 감사하겠습니더!!

  5. Спасибо за работу, и особенно за русские субтитры. Очень познавательно и полезно!

  6. 영상 감사합니다! 이와 비슷한 실험을 외국에서도 진행한게 있어서 참고삼아 링크드립니다 https://youtu.be/ZI3SyGjjbfw

  7. 백넣을땐 각도를 작게 하고 니꾸 파이널은 각도를 크게 쓰는게 좋아요.
    이유는 텅스텐 각도가 작을수록 침투력이 깊어서 백넣을땐 스라가 잘녹고 니꾸 박을때 백 빨림을 방지하고 크리에이터 잡을때 핀홀 생김이 줄어들며 열이 분산되어 좀더 높은 전기를 사용할수있기에 용접 속도를 올릴수있습니다.
    영상에서 빽까지 침투력을 같이 봤었으면 좋았을텐데 아쉽네요
    영상 잘 봤습니다

  8. 파이프 용접 마지막에 텅스텐봉이 가열되었다 식는 속도, 용접이 끝나자마자 텅스텐 봉의 달궈짐 정도를 보면 텅스텐봉 각도가 적을수록 더 높은열이 집중되는것으로 보입니다.

  9. thank you very much for the subtitles. I like videos about experiments. There are always myths in welding. Thanks from Colombia in South America.

  10. 안녕하세요 알곤 용접기는 회사에 있던데… Tig 를 하나도 몰라서요
    1. 350A 하고 WP-26 하고 같은 규격인가요?

    2. 롱캡,숏캡,중캡? 이런건 왜 구별하는건가요?

    3. 유리로 된것도 있던데 텅스텐봉이 잘보이도록 하기위함인가요?

  11. 매우 흥미로운 영상이네요~ 조만간 필러와이어를 공급할때의 텅스텐각도의 영향 영상도 가능하실지요?
    그리고 용접시 산화(블랙 옥시드)를 최소화하는 방법을 알고계신게 있으신지요?

  12. Could you tell me please why I have sometimes go dark seams, in than the problem. The gas is clean, the parts are cleaned. Overheated, or driving slowly.

  13. 영상 흥미롭게 잘봤습니다ㅎㅎ

    생각만해보고 실험은안해본부분이었는데 생각했던것과 같은결론이네요.(저도 용접비드에 큰차이는 못느끼지만 텅스텐각이 크면 토치가 빨리뜨거워져서, 장비관리차원에서 얇은각을선호합니다ㅋㅋ)

    영상에서 텅스텐봉 식는정도를 봤을땐 얇은쪽이 용입이 약간이라도 깊을거라 예상되지만,
    세로로 잘라서 단면을 확인해보면 더 정확하게 답이나오지않을까 싶습니다

  14. I work at the dairy plant, we have requirements to cook with a blower. If I increase the speed and reduce the amperage there will be no penetration from the inside. As you know I have to have a double-sided seam, both outside and inside. Tungsten I have a 2.4, the nozzle 7, pipe stainless steel 1.5 millimeters.

  15. Muy interesante tu experimento, en los libros se insiste mucho en los angulos pero con lo que hiciste vemos que no es una variable critica , gracias

  16. Why sharply sharpen the electrode? At any angle of sharpening, the end of the electrode takes the form of a non-breaking drop.On holders without electrode cooling, sharpening the electrode leads to marriage, tearing and penetration of the metal of the electrode into the weld metal.

  17. Какая глубина проникновения сварки? В трех режимах? И толщина металла?

  18. 에어호스 연결하는 에어커플러(소켓)인데 재질 카본, 서스류는 아니고 일반적으로 사용하는 (주물?)재질입니다. 카본 파이프와 용접할려고 합니다.
    알곤 토치로 전류 80a로 맞춰 잠깐만 용접해도 에어소켓 부분이 푹 파이면서 가접조차 안되던데 용접하는 방법이 있을까요?

  19. The inside we didnt see the inside penetration !
    Also can you the same test with different tungsten distance from the metal? For longer arc test. Wah tungsten gives the best results wth on loger arc

  20. Мне кажется, что совсем не информативно. Потому как одно дело просто вести дугу по сплошному металлу и совсем другое заполнять присадкой сварочный шов. Там все должно быть по другому и угол заточки будет влиять сильнее потому как работает формула плотности тока на 1 мм2. При угле 15 град провар должен быть глубже (на мой взгляд) чем при угле 60 град потому как плотность тока на 1мм2 больше за счет концентрации дуги. Мне кажется так.

  21. いくらテストでもパイプ巻くなら開先しっかり取りましょう。こんなんだから海外の溶接製品ダメダメばっかなんだよ海外製品でどれだけ日本の企業が苦労してるか。欠陥だらけの製品ばっか造りやがって

  22. Terimakasih ilmu yang kau berikan,,
    Sungguh sangat bermanfaat sekali buat para welder pemula seperti saya🇮🇩

  23. I still believe that the difference is big even between 25° and 35° but its situational. I want the heat focused to one point especially on material that transfer heat fast, its also easier to burn away pipes if you manage to get some. Im also pretty sure that a sharper electrode angle give a tiny bit more penetration, even if its not alot. It makes sense, if you get a slightly wider weld you also get slightly less penetration as long as the energy input is the same.

  24. I use this disk in my 18v Makita battery grinder to sharpen my tungstens . can sharpen drill bits to and more .  https://www.ebay.co.uk/itm/283337062859
    best thing about using this is it is its portable

  25. Exelente tutorial grasias por el video solo si pudieran traducirlo en español seria de gran ayuda felicitaciones

  26. Thank you very much in Russia there is not so detailed information about this process. Everyone sculpts what he wants 🙂 I start to study under your beginning Thank you.

  27. que linda soldatura tan elegante correcta penetrada pareja a los lados sin socabura mucho respeto maestro y muchas gracias por la grande esplicacion de la afilatura del tungstenov muchos saludos

  28. Завораживает сварка любая. Вот интересно стало если все 3 пробы на разрыв испытать

  29. было бы интересно разрезать образцы вдоль – посмотреть швы в разрезе…
