You will look like the most skillful worker! Fastest sanitary pipe TIG welding 

HAHAHAHAHAHAHAHAHA !!!

HAHAHAHAHAHAHAHAHAHA !!!

Stainless does not need filler metal addition as it does not lose ductility with temperature (hot short) so it won't shrink crack on cooling. Yes, there is oxidation on the outside from excess temperature leading to the frosted looking weld (gray) but no black or green "sugaring" which indicates loss of chromium or nickel which would cause corrosion sensitive or brittle weld respectively. Both Cr and Ni oxidize in air at glowing temperature and higher, Cr confers corrosion resistance, Ni confers ductility as it stabilizes austenite structure. Cr alone would make the steel martensitic which can be brittle so Ni is added to stabilize austenite which is highly ductile. I'm a dabbling welder but I know my materials science as applied to welding.

I'm literally starting a job doing food grade stainless. The one thing I noticed 160 amps is way too high. You supposed to do maybe 110. And when you start at you're supposed to stay in the same spot at least six seconds and then you need to walk the cup. When you look inside it didn't penetrate at all. There was also no "devil's eye" in the weld pool. Which indicates proper penetration.

@@joeyvillalona478 Did you see the cut made after the weld to show penetration? Looked good to me.

@@keithjurena9319 looks kind of thin. My understanding if you penetrate it just right you would have had a slightly wider and a gold looking bead

Welding stainless sanitary tube is supposed to be welded without filler. Penetration looked exactly as it should. The weld on the inside and outside should be close to flush. I believe the intent of this video was to demonstrate a technique to weld sanitary tube very fast. I would imagine that this technique also aids in reducing shrinkage and warping due to being welded so quickly and presumably having less overall heat input into the part. I am a sanitary fabrication specialist and I approve. I don’t believe you know what you’re talking about, but I would love to see some of your sanitary welds to prove me wrong and back up that 10 years expertise.

yes of course It is also possible to apply a laser welding machine to this method.

@@weldHAGOJIBI Would love too see a video. Would you have too purge the pipe?

They must not have worked with sanitary systems. Most of what goes into semiconductor tooling is exactly this type of weld or fusion. Just because you are good at a few methods doesn’t make you an expert at everything. If it were going into tooling, it would be tested for any leaks and get approved or rejected. His weld isn’t the best, but it’s typical of what’s out there. Can confirm, 7 years experience welding for the semiconductor industry including Intel and LAM Research to name a few.

Well, this is a demo, we see that he HAS stuff to do back-gas for instance.

I've made welds exactly like this in brewer's, distilleries and other beverage facilities.these sanitary type welds are what is required for cleanliness reasons. As far as I know this is really only applicable woth stainless tubing.

yes

1티 이하는 잘 아시겠지만 턴테이블 있어도 한번에 가기는 힘들어요. 하지만 샵장인데 턴테이블 없다는건 작업성 많이 떨어지는데 기본적인건 갖추고 작업하는게 회사나 일하시는분이나 좋다고 생각합니다.

@@user-ue7ri5eb4m 공감합니다. 근데 회사규모나 지속적인 작업이 없으니 크게 어필 할 상황은 안되서 아쉽습니다. 회사에서 하는일이 식품회사이고 기계정비나 시설보수이기에 자주하는건 아니다 보니 비싼장비를 쓰자고 하기가 힘듭니다. 그래서 마음 같아서는 레이저용접기를 쓰고 싶기도 한데 자주쓰는것도 아니기에 어필하기가 많이 힘듭니다. -.-;;🥲🥲

@@ice11110 식품회사 쪽이시면 쎄니타리 용접이 주된일인거 같은데 그렇다면 레이저 용접기 까지는 몰라도 턴테이블정도는 욕심내는것도 좋은거 같아요. 가격이 그렇게 비싼것도 아니라 사측에 크게 부담되는것도 아니고요. 다만 장기적으로 봐서 식품쪽이면 레이저로 가는게 순리인거 같습니다.

@@ice11110 꿈이 크십니다.. 한국사장들에게 무슨 기대를 ^^;;

@@user-fk2zi2nu7e 그러게요.....쓴소리만 잔득 들었습니다.ㅎㅎㅎ

Yes. Needed filler rod

3 мм - 75 А😊

ye 90 ampers is good on 3 mm

Hot and fast. You know what country this is made in? This is how they keep production quick. He is also using a positioner/rotator which makes this easy.

@@SupraSav I know this is Korea. And I know this was semi automated with rotary positioner. Also argon purge inside and gas lens torch. My point was this was 70 amperes higher than normal for this thickness.

Здесь получается нижнее положение. Металл 3мм. По учебнику и опыту нужно в среднем 110А

Because there are too many variables, we do not use a set formula. I use my fingers to imagine the image and apply it to the actual welding.

Put a mark at the 12 o'clock position. Turn it on and count how many times the mark hits the 12 o'clock position in one minute!

Это просто реклама вращателя.

да он читер, пусть так без приблуды сварит и он великий сварщик.

И чего тут сложного ? Тем более с поддувов варит .

Это(не извиняйте!) - хуйня декоративная,а не сварка.Отшибу на раз резиновым молотком,даже не погнутся края - нет корня-нет прочности.Этот способ может пригодиться для стульев...но на китайской фабрике стульев.

Без присадочного материала образуется усадка внешнего валика шва (да там просто нет усиления ). В ответственных изделиях это не допустимо! А в гараже дяди Васи пойдёт.🥱

@@goblis1 На одном из популярных каналов по тиг сварке Тиг Миг Евгений Лысенко ( автор), очень много знающий и умеющий сварщик с большим опытом работы показывал на своём канале о практике сварки нержавеющих труб своим телом . Это практикуется и проходит контроли и ГОСТы по всем показателям.

It's silver inside. It's only going to look better if its all nice and filed then wiped down with acetone instead of straight from the mill and covered in finger prints.

제보 감사합니다. 그 사람들이 이런건 좀 안했으면 좋겠는데 속상하네요

@CarbonBacon V lmao oh so triggered

Agreed. That's a fail under the AS/NZ code.

Root is fused,its hard to see.the weld itself is sunken in in the middle.that weld would pass x ray

@@samuro843 I've seen an inspector fail a weld like that with sunken middle here in NZ. Not enough filler wire.

@@samuro843 so yea it has fusion but I wouldn't use that technique for a test. Shalom.
