Hello everyone.
TIG welding beginners will have had this experience when welding carbon steel.
Dirty weld beads!
This is because TIG welding has the disadvantage of being vulnerable to foreign substances.
Today, I will briefly introduce the solution to this.
Thanks for watching and have a nice week.

Перед сваркой нужно зачистить разделку кромок и околошовную зону? Кто бы мог подумать, это же секрет древних буддистов!
Nice work I guess you could say, Proper preparation prevents piss poor performance!
Buen tutorial maestro, lo primero limpieza, limpieza y mas limpieza y sobretodo en el aluminio, gracias por compartir sus conocimientos y experiencias, un saludo cordial y por supuesto un merecido like desde Narón (Galicia)👍🤓😜
As a professional welder, tig 100% has to have a clean surface. No matter the metal
A fingerstool is a must for Tig welding which absorbs the heat and allows firm control over the direction of metal. 20mm Pipe welding at a 45 degree angle with root fillers and cap will wreck anyones wrist.
you learned me 90% of all my weld knowledge, i thank you very much sir, i had no experience before but wanted to be a welder so bad, its my passion and i learned so much of you. now im a fulltime welder and im living the dream. thank you❤
Спасибо! Отличный наглядный пример. 👍
It's all about having clean metal to weld , no oxides no rust no contaminates and good gas flow 👍😉
Excellent Video Quality and layout explanation. Camera angles perfect and lighting. Thank you so much 🙏
¿Que no hablan de esto? Si es lo primero que se aprende...limpieza y eliminación de oxido, pintura, etc. Excelente vídeo.👍
On the contrary, that is the very first thing you learn from a professional TIG welder. Prep, clean, then clean some more, repeat and then maybe you get to lay a bead that most probably will look like burnt chicken shit anyway. Unless you have mastered all the other hundreds of variables and techniques involved to get something even remotely resembling the clean bead in this video. For all the amateurs out there interested in getting into TIG welding because you've seen some weld porn on KZhead or Instagram. What these porn producers wont tell you about TIG welding, is as follows. (and I've explained this to a handful of friends over the years who caught the TIG welding bug and was about to run out to buy their first starter rig.) Provided that you already have access to an insured, relatively weld safe workshop where you have enough power and permission to store large high pressure gas bottles. You will need. A sturdy metal worksurface to weld on (tin clad wood will burn and smolder for hours if not days). An angle grinder with a decent selection of discs for cutting and grinding. A fire extinguisher. Protective closed leather boots. Protective clothing made from natural fiber, wool or leather (Most synthetic materials will burn so fast you have little to no time to react. Especially when your vision is limited by a welding hood.) (Synthetic fabrics are basically low density plastic which will burn, melt and stick permanently to your skin resulting in severe burns and hospital bills.) Now you can go out and buy the most basic Chinese TIG setup you can get. Apart from the initial cost of the $500 welder, you need to buy (or rent) an argon gas bottle, pay for filling it, Buy a gas regulator, fittings and hoses. Buy a decent welding hood (don't waste your time trying to use the one they might include with the machine for free). Buy electrodes and filler rods for the different materials you wish to be able to weld and so on. That should set you back about $1000 in total. However, if you want some kind of quality product where you don't have to curse the machine and all the cheap components on a regular basis, you can look forward to spending $2000 and upwards on your setup. Believe me, learning to TIG weld is difficult enough without having to second guess your equipment. And if you want the option to weld aluminium you will have to spend yet another $1000 dollars just upgrading from a DC to an AC/DC machine. Also if you care about your long term health and want to avoid slowly getting poisoned by toxic, cancerous smoke and gasses you might want to consider buying a welding hood with a forced air respirator (gas mask), that is at least another $700 and upwards, plus the added joy of buying and replacing filters and charging batteries on a regular basis. Even though expensive, respirator hoods are well worth it because you will spend long hours exposing yourself to the fumes while training before you can even hope to produce a half decent weld. Getting a decent respirator hood is a good idea for the other processes as well, but especially with TIG because you basically don't have the option of working outdoors, or in a well ventilated room, because of shielding gas coverage issues. If the nozzle experiences the smallest amount of wind or moving air it will ruin your weld completely and foul and/or burn your electrode as well. MIG welding basically has the same problem (since it's also gas shielded) but is a bit less sensitive to wind, and you can also choose to use a flux core wire which gives you more or less complete freedom to work outdoors in most cases, which of course limits the risks of inhaling the toxic fumes. As they say, "very few welders get to see old age". TIG welding is by far the most time consuming and expensive of all the common welding processes. Not to mention the hundreds upon hundreds of hours you need to spend training before you can produce something even remotely close to what this guy does on ordinary black steel (carbon steel). Good results on aluminium and stainless is at least another couple of hundred hours. If you care the least about the results, prep, cleaning and setup takes up at least 75% of the time if you are welding regular black steel. But will take up closer to 90% of the time when welding stainless, aluminium or even more exotic materials. The material must be completely free from mill scale, rust, oil and other contaminants and then thoroughly cleaned with pure acetone. Less pure acetone or brake cleaner might contain chlorine which will produce deadly chlorine gas when burned. And now, what probably got you exited with TIG welding in the first place, those perfectly rainbow colored weaves or stacks of dimes will put your budget upwards of at least $5000 and you will have to spend thousands of hours studying how to weld and manage heat spread in stainless steel to perfection in order to achieve that. If you ever get to that point you are now in the top 20% of professional TIG welders. And even those guys only put up pictures of the one or two nicest looking beads they were able to produce during a 40-50 hour work week on Instagram. So unless you want to dedicate your life to a career in welding, forget about the perfect rainbows. Also, the rainbows are an artefact which is not necessarily wanted by the end customer. IE companies don't pay their welders to produce pretty rainbows unless it's a show piece or for an artwork. Their main concern is of course the structural integrity of the weld, which is hard enough to master. Just in the process of learning TIG well enough to produce a half decent weld bead you will spend months just prepping and cleaning material and filler rods, grinding tungsten electrodes into pounds of cancerous (and in some cases also radioactive) dust. And believe me, you will spend some time demounting and regrinding and remounting and adjusting your electrode. The smallest amount of contamination (most often molten steel from accidentally dipping the electrode in the weld puddle or striking the electrode with the filler rod) will make your arc wander or pull and make it even harder to get a good result. The different methods of grinding tungsten (one of the hardest metals in the world) electrodes while avoiding the hazardous dust is a long discussion in itself, ready made relatively safe tungsten electrode grinders will start at about $600, there are other options, but what ever you do, be very careful not to inhale the dust. So if you are only working with black steel, my suggestion is to buy a MIG welder, spend 50 hours and become a half decent at MIG. The cleaning and prep work is about a tenth of what you have to deal with as a TIG welder. And you will lay down the beads three times as fast as with TIG. There are options for MIG welding aluminium and stainless steel as well, but it gets kind of complicated with different gas mixtures than the regular 80/20. A decent MIG setup is about half the price of TIG, and you don't have to be as particular with your hood choice. Same thing goes for stick welding but it's even cheaper (roughly $200 gets you in the door) and stick can be even less sensitive to clean material than MIG depending on the choice of electrode. Though it takes more time to learn and is a bit harder to master on very thin material than MIG. But you can always be outdoors in any kind of wind as long as your material is somewhat dry from water. However if you are hellbent on trying TIG. Start by taking an evening starter class. Or if you know someone who owns a TIG setup, ask them if they are willing to show you the ropes.
Some Welders don't say shit because that's how they make money. They just work.
Zajakallah I had a confusion on this long time . Now I am clear with this video
Prep work sucks but it is absolutely critical!
Wow, I am an insurance agent and I wanted to see what one of my clients did for a living to understand and this TIG welding is beuatiful , what amazing technique this is, I would not mind a hands on lesson.
Note how the electrode is weaved and no attention is being paid to root penetration. This would fail a coded test for insurance.
Really, no one knows you have to clean your material first? So glad I watched this or I may have been clueless with what was going on if I ever forgot to clean my material.
préparation is 80 % of good welding ,thank you
What tungsten you use?
First of all, your welds are just as they should be..you're a professional. ;) I always taught my apprentices to clean their workpieces before welding. I know in the world of today time is money and it has got to be fast and cheap. However, a good weld always requires some preparation, especially TIG or MMA. You showed what happens when it's just welded away. A lot of slag will form due to the mill scale and impurities in it which melt and flow on top of the weld puddle.
At 86 I have just bought a tig and not tried it yet but have watched quite a few videos and am still feeling confused and am wondering if I will get as good a view of the puddle as are shown in the videos ?
@@alandouthwaite6980You will be looking from further distance something like this 4:00 , but it just depends on how close you put you head to it, but you absolutely will not be as close as the camera when he is welding
@@makl196 Thank you for your reply, at least I know now what to expect. Nearly ready to have a go now...if I can set up my new helmet !
Fantastic❤
용접 전 클리닝 중요하지요 ㅎ
Я такой сваркой работал на заводе толстый метал варил на ура, а тонкую нержавейку лишь через месяц научился варить что бы её не прожигать,смотрел ваши видео уроки не плохо помогли они)
Странно... Для толстого металла придумали полуавтомат MIG/MAG и сварку под флюсом, они больше всего могут "залить" металла в сварные соединения, это самые производительные виды сварки. А сварка TIG/WIG как раз для нержи и тонкой работы придумали. Меня аргонщики учили на 1-1,5 мм нерже, чтобы прочувствовал дугу, толще 10 варить можно, нифига не эффективно
great stuff !
I would be more than pleased if mine came out like first one
😂
Everyone starts from somewhere and with a little training you will be welding like the best.
I'd settle for the bad one in the the thumbnail

So dirty, maybe some inclusions and fail NDT? Preparing the weld area is the most important step. Doubly true for TIG work. Good prep work will help achieve better looking welds. Practice will gain consistency.
Nei tuoi ultimi video non usi la voce. Le tue precise istruzioni erano di grande aiuto sia per imparare e sia per confermare le intuizioni dello ascoltatore. Esiste un preciso motivo per questo cambiamento? Io leggevo le tue istruzioni col traduttore automatico nei sottotitolo in italiano. Grazie
I can understand everything I'm glad that you do this and for all languages. 🇺🇸

This needs to be done for stainless as well to remove the chrome and nickel oxides
hey, may i ask u what is ur reference helmet, love ur content
일단 클리닝을 안하면 용융풀이 윗부분쪽에 융착되는게 뒤쪽에 보여서 이게 융착이 된건지 안된건지 쇳물보기가 힘들더라구요. 근데 전기용접으로 태크 놓고 그거 그라인더로 갈아냈는데 꼭 티그용접하면 클리닝 안된것처럼 쇳물보여서 힘들던데 이건 해결책이없을까요?
없는것 같네요 아크는 CO2 쉽게 수정가능합니다.
반대 상황을 예로 들어볼게요 아크용접시에 티그용접봉을 용융풀에 대면 즉시 부글부글 기포가 생깁니다 그걸보면 용접 종류마다 용접봉의 재질이 다르다는 것을 알 수 있다고 생각해요 슬래그 성분도 당연히 다르고요 시오투로 테크놓으면 용융풀이 끝나는 지점에 슬래그가 혼입됩니다. 당연히 더럽죠
How much time it will take to learn it
Nice video, subscribed :)
Sim mestre essa é mais uma grande aula devemos saber que para obter uma soldagem boa é preciso também ter uma limpeza 100 % da peça a ser soldada para termos qualidade em todo o seu prosseguimento até o final show 👏🙏
Very Good 👍
danget now every time i do this weld this song must be on in my head for it to work
Please, please make more videos of Stick and wire feed welding stories. I subscribed and will turn on notifications. Thanks 🙏
Weldingtipsandtricks provides you with regular information on what subjects you want.
Easy answer!! : professionals already know to clean their materials!! Its like saying "i got in my car and drove to work". "Ok well did you turn it on?" "Yeah ofc i did"
No one talks about it because its just natural to clean any material. You should never weld over mill scale
Why they don't talk about it? Because they all know your welding area should be clean. ffs
역시 용접최강
i now hear this music when im tig welding and i love it.
Why dont welders talk about this? Because there down the pub or checking there football bets. 😊
Ask a plumber what his tricks are.
Ну что вы в самом деле? Первое что говорят профессиональные сварщики: TIG сварка только на зачищенный и обезжиренный металл. Второе: не зачищайте отрезным кругом - он не рассчитан на боковое усилие и может красочно лопнуть (да я тоже ленивый). =)
TOP!👍👍
Merci
What cup size is that?
The dirt is problem? I mean the dirt is stay top of the weld or also in the weld? Is effects the wels strengths or just a ecstatic problem?
The mill scale and rust will become inclusions in the weld and become faults in the weld. Weakening the weld creating failure under stress. Structural welds often go through Non Destructive Testing. Magnetic particle, ultrasound, or radiography. The weld flaws will be revealed. These spots will have to be rewelded. Most structural welds are expected to have a 94% pass rate. Too many fails and the welder is fired.
Good one
They talk all the time that you need clean / prepared surfaces if you choose to TIG weld …
In any welding prep work is key! Even with brazing.

I have encountered welding objects on the construction site that are full of chemicals such as hydrochloric acid, strong alkali, etc. Tell the owner that he still requires you to weld directly without cleaning

0:26 is laser welding any good? Is it as fast as shown online?
Yes, laser welding is fast and give nice results but it gives less heath, so connection may be weak if you weld to fast. However for thin plate laser welding is always the best solution.
Ive always been taught to clean your workpiece. You never want to mix rust or other impurities. The reason why that hotpass looked better at the bad side is because the first weld got a lot of the mill scale out and whatever it was on the metal.
그라인더 하기 귀찮으면 용접사 그만둬야지요 ㅎㅎ
So kids, always remember to clean your plate
good
Argon blowing out that cup so hard these two welds probably used 2000# each.
I’m glad he cleaned that shit cause I was about to lose it lol

Спасибо. Класс!!!🦾🦾🦾👍👍👍😁
Что за присадка???
8 мин показывать что нужно зачищать металл)😂варишь неплохо,но сталь металл в целом не трудно сваривать. В России на заводе каждый 2й сварщик сделает так)
Also remember to clip the burnt ends of your filler rod before continuing to weld with them
Какая прелесть 👍

티그 용접의 단점...
You are clearly a master welder and I am not, I just have good eyes ;). I found one mistake, you should clean the welding area before you tag the plates together, so then the root is totally clean too between the plates.
Ну чистить и под обычную желательно. Это ещё аллюминий не показал,там при плохой зачистке вообще содомия.
Why don't they talk about this? because this is day 1 in welding school
I'm a welder and the first thing I've always been taught and one of the main sayings of welders is "preparation is more than 50% success" so this title that says welders don't talk about it c is false and misleading!!! if you see a good result, you must always clean the metal, remove impurities, scale, slag, ... the metal must be clean, then a little acetone can degrease and the same on the filler metal . every time I was asked I always said, we prepare the material, we clean it, we clean the parts to be assembled and welded, and off we go. it is not for nothing that a welder's table and his welder are always very clean, the welder reflects his personality, if he is clean he is a meticulous person, if he is dirty, you know the rest. nice video on the other hand, but I don't understand sign language.

아하 순전히 클리닝 차이인건가요?
용접의 기본은 준비 과정 이지요 품질을 높이기 위해서는 반드시 산화막을 제거하고 용접 하는건 기본중에 기본 입니다.
You did go faster on the grinded area which makes cleaner and nicer welds and if you are actually trying to educate you would have mentioned that.
What have you missed that you have not mentioned though showed that cleaning the metal is important to obtain a good clean finish? Answer: The mill scale should be removed fully on all joints before it is tacked together, not after it has been tacked together. You should show the difference in results and the effect it has on penetration under the plate.
You are never happy so !!!!
@@zibobpompon5768 it’s the difference between a good weld and a weld that will fail in service. I am speaking from 40 years of experience.
Actually he did grind it out and it shows lack of penetration. Maybe watch whole video?
Sometimes it isn't in the welder's power to do so. Fitters may not prep the weld area at all.
@@Sasquatch-ff1pj It the fitter didn’t follow proper procedures, I send it back because if the weld fails I can end up in jail. But if the management wish to push the issue it is my responsibility obtain a waiver that transfers all blame onto them.

No Time to prepare when there are too many pieces to weld and when its hidden
티그 기본 갈고 해야지..
😂😂😂¿,,por qué los soldadores profesionales no hablan de esto?, pues porque es algo muy,muy básico. Limpieza en TIG ABSOLUTA
What’s with the no preparation of the metal?
That's what he's trying to show--GTAW does not like mill scale or rust at all. No welding process does but the others have ways of mitigating the contamination--TIG does not so the base metal must be as clean as possible.
@@locomike102 yes I understand that. Cleaning is imperative to maximum quality and when all edges are cleaned properly your welds are guaranteed to last for many years. Because it has been cleaned after tacking you still have the oxidised mill scale trapped between the two pieces of metal. Mill Scale is Oxidised metal and contains moisture that can lead to cracking from hydrogen trapped between the two plates of steel.

Nice welds, but what’s up with game of charades? I’m new to TIG, and I have absolutely no idea what you’re trying to communicate with the hand gestures.
