I haven't seen this quality of aluminum welding in over 30 yrs, my son's god father who worked in a sheet metal fabrication shop was the go to guy to do aluminum welding, and he was the best of the best, and this gent doing the welding in this video should be proud of his work, kudoos to him and keep up the great work, as for the keyboard Karen's, well all I gotta say is if don't know then shut up watch and learn !! Have a great merry Christmas
Aluminum is hard to weld, because it doesn't puddle up, like steel does, instead it justs gets a wrinkle look, then a few seconds later after the wrinkle look, the aluminium just falls apart, so its crucial to get your welding rod into the wrinkle area, just as it wrinkles, them keep moving, before the whole wrinkle area, just falls off, in one big blob. Also, its good to use an aluminum flux when welding aluminum, for a better looking weld.😁👍
I would use mention instead of tell, but I get the picture. This guy could even fix a 6061 aluminum bike even though 40,000 psi is plenty of tensile strength. Stronger than carbon fiber in general.
Takes a bit of practice but can make a very sound weld using gas torch with aluminum arc welding rod as a filler rod. Can use in the field without electricity. Was a common practice in the early part of to 20th century. Easier to do if you have a pair of the old blue lensed gas welding googles so you can see when the base metal starts to melt. Over the past few years I’ve done several successful repairs this way and have tested several samples that achieved full penetration welds stronger that the base pieces being welded.
The way I’ve been doing this, the weld is fluxed and shielded by the flux on the arc welding rod I’m using as a filler rod. I’ve also done some welding with no filler rod or with bare aluminum filler strips where I cleaned all materials by sanding or brushing with an un contaminated stainless steel wire bush and welded using the aluminum flux sold by Tinman Technologies (a good source for speciality tools for sheet metal work and sheet metal welding) - off hand I don’t know what is in the flux which is supplied as a white powder you mix up with distilled water.
How do you know if your aluminum is hot enough to weld, but not so hot it falls apart? 1) you should clean all that comtanination out. 2) turn your torch to where it is just burning acetylene. You want that orange/black sooty flame. Put the torch on the metal and get it black. 3) Turn your torch to the proper heat for the job. 4) now heat the material. The black soot will burn off when the metal is ready. This works well before you TIG weld or any type of aluminum welding.
Para ese trabajo hay algo que se debe tomar en cuenta, muy simple. Remover lo que pueda alterar la aleación, como pintura, grasas y polvo. Lo aprendí desde cuando por mi calle pasaba un señor con un bote con brasas y fierros de bronce para reparar trastes agujereados. Su herramienta era básica, pero lo principal era ácido muriatico. Yo era un chico como de ocho a diez años. Nunca imaginé que trabajaría en la soldadura moderna, pero lo que más conservo es la igiene y ética al trabajar y que mis empleadores me aprueben. Aquel soldador de antaño se anunciaba con una flautista de plástico, hoy con una carta de recomendación o con buenas referencias.
Learned this 40+ years ago in high school. It’s best to clean all surfaces and wipe them down with acetone before welding, makes a cleaner, stronger and better looking weld
Please correct me if mistaken and supporting evidence. This cannot be welding but brazing or soldering. The base metal is not forming a puddle; not a fusion of base and filler metals.
This is gas welding. He is forming a weld puddle, and manipulating it with the butt end of a steel welding rod. The filler material is a fat bit of aluminum, which is added at times, then he goes back to working the weld puddle with the steel welding rod. When you see the welding rod, he is not adding filler, just working the puddle. The parent metal and filler are all blended together. That's not low temp zinc he's using for filler, it is aluminum, which means the parent metal is being heated to the melting point.
@@vandalsgaragetambién por cuestiones físicas y técnicas la soldadura queda con pequeños poros internos q debilitan el material, no va tener la misma resistencia una soldadura realizada como en el vídeo a una por electrodo revestido o por proceso tig siendo este último el más resistente, esto no quiere decir q este mal lo del vídeo solo q es otro proceso y no es el óptimo pero cumple su función.
Keren mas 👍👍👍 thanks udah share.. Mas mau tanya perbandingan tekanan/presure gas CO2 sama LPG nya berapa untuk menghasilkan las2an alumunium yang solid??
What I see is, the process of extracting dross from the surface of the puddle by using the arc welding rod to collect it by a scratching technique. The preliminary weld to secure the parts in place is cleaned in preparation for the filler rod, after the application of the filler rod the weld is again cleaned by pooling and scratching. The same thing happens when you melt ally for casting, before pouring ,the dross is removed with the help of a steel sieve. Great work...
Looks a really skilful job. What gas is used here propane or poss Argon or a mix?. Steel rod to remove Oxidisation and filler rod where necessary?.great anyway.👍
Most of the time, he's manipulating the weld puddle with the butt end of a steel welding rod. Then adding a little filler, and repeating the process. He is melting the parent metal, and adding filler, literally the definition of welding. If you think it looks easy, its because you've never tried to do it.
Salut! La lucrări de tinichigerie de îndreptare ce pot folosii pentru finisaje la temperaturi joase atât pe aluminiu cât și pe metal, ma refer sa nu mai intre asa mult chit, mulțumesc
well let's see.....it shows him at the start of the video opening the valve on an oxygen tank so I would guess it's oxygen and propane....but we'll let you figure it out Einstein 🤨
Припой не главное. Главное это в качестве груза; на алюминивую крышку положить аоюминивую головку. Это конечно шутка. А сварщик спец. Нужно чувствовать прогрев алюминиевой детали; чтоб не потекла от перегрева. А хаотичными движениями припоя сбивает оксидную пленку на крышке.

there's flux already on the rod
Thank you, great skill with the torch, so easy to blow through the metal
it's not that hard. you just need more practice
Formidable tecnica.muy basica y efectiva.gente muy lista y experta.felicitaciones
Bravo !!! grande saldatore !! i mie più sentiti complimenti !

Ótimo Soldador parabéns pelo Bom trabalho que você Faz ..
EXCELENTE VIDEO¡¡... Y MUY FACIL DE ENTENDER¡¡...SALUDOS DESDE MEXICO¡¡
Good job, looks like works well for you.
Takes practice to not put too much heat in that piece.
Congratulations! Simple and efficient. Big hug from the south of Brazil!
😂kkkkk se der vazamento por falta da penetração que é bem provável vai ter que lixar tudo novamente kkkk
Mas ele deve ser novo ele aprende kkkkk

The old cobalt lenses. I think glass blowers still use them.
I know that you use borax when you weld with bronze. Is it the same with aluminium?

@@mitsos306ify it's same used borax

Great video, what type of electrode do you use at the beginning of the repair ?

Propane limits temp. Read description! See prior videos on casting rod!
Merci de l information!😊
Las barras llevan fundente o como sería alli???

Early days I gas welded aluminum but I must admit I like TIG better!
Thank you for always sharing your great techniques, there are few who share this valuable information, I accompany you here from Brazil😃
I just found your channel today, and have been watching your videos all afternoon. Very nice work.
What are those rods u are using and what flux are u using
Gostei muito bacana dimais você é professor
Soldado e com acetileno e oxigênio e

Boss would fire me if weld looked like that.
very cool!!!great video!!!

Mas mau tanya perbandingan tekanan/presure gas CO2 sama LPG nya berapa untuk menghasilkan las2an alumunium yang solid??
Eu sou do Brasil e gostaria de saber qual o tipo do gaz..porque eu conheço o gaz vlp que e o gaz de coxinha mas esse eunaoconheco
Muy bien mi chingon
Are you using propane or acetylene ? With the oxygen
Propane, read description!
Jos mantap
Kerja yang bagus 👍
Man is good! I mean he is really good!
That will work Dr. Frankenstein
je heb gelijk deze gozer moet naar school !!
It works better when you clean the aluminum
Mucha habilidad y experiencia
I guess the reason why no one tells you about these welding tricks is, parts like this nowadays are made of plastic, especially in the auto industry.
Dude. Alumiweld. You're welcome.
Can you please tell me the rods being used here. Thanks
likely ER4043 filler rod for doing work on cast parts, it's an aluminum-silicon(5%) alloy filler rod.
溶接ですか？それともロウ付けですか？
Alumiweld works good also.
You use LPG or acetylene
Tope dimais você tem que mostrar se e com gas de cozinha o acetileno
He soldado aluminio pero hoy aprendí que se suelda sin fundente y a destorcer o acomodar la pieza sobre la marcha a puntos

Expecting more videos
Not many know how to weld with water as a fuel. My MultiPlaz welder does it with ease.
Looks a really skilful job. What gas is used here propane or poss Argon or a mix?. Steel rod to remove Oxidisation and filler rod where necessary?.great anyway.👍
Acetylen 👍
Gak terlihat pemakaian fluxnya, tapi kok bisa nempel sempurna ya? Mohon petunjuknya suhu 🙏
Yang dia pake itu kawat las khusus buat las alumunium, banyak di jual di toko bangunan
Saya pakai kawat khusus tetap ndak nempel, mungkin kurang kuat apinya
@@educhannel3377 selain itu media yg akan di las harus di panaskan
Very good
Impressive
¿No ayudaria una lijita, jabon y agua si no hay mas?
When you clean up that, Weld? , I would think the part would just fall off. Looks more like a solder job maybe a braze at best.

He is melting the parent metal, and adding filler, literally the definition of welding. If you think it looks easy, its because you've never tried to do it.
very good but CO2 gas?
Я тоже подумал а не O2? :)
Попробуй сварить тонкий алюминий умник.
铝焊药是什么成分？
Bang apa perbedaannya kalo ngelas aluminium pake acytelin dengan gas elpiji
Это же пайка... Ане сварка
Nope
Mas info nozle stang las nya dong 🙏
Old Style Bro, We call that ALUMAWELD...Lol...
Флюс для сваривания почему не используеш ??? С ним же легче сваривать наверное.
Artistry. Anyone who thinks this is easy (or mistakes it for brazing) has never tried to gas weld aluminum castings.
Que medida é a estenção de solda que você está usando?
This welding rod is of which material ?
Same question
Repurposed aluminum scraps
Salut! La lucrări de tinichigerie de îndreptare ce pot folosii pentru finisaje la temperaturi joase atât pe aluminiu cât și pe metal, ma refer sa nu mai intre asa mult chit, mulțumesc
Pakai acitelyn apa lpg mas?
wat is the alloy rod
Sir what kind of torch did you use ?
Tig сварка сделал бы в 10 раз быстрее и 50 раз красивее,, этот метод известен уже почти 100 лет.
Isn't that the head from a previous video that you "fixed".? Seems it's a paper weight now
Hola el electrodo que usas que tipo es gracias
Remove excess flux after welding by washing off with boiling water
is that straight propane or oxygen too?
well let's see.....it shows him at the start of the video opening the valve on an oxygen tank so I would guess it's oxygen and propane....but we'll let you figure it out Einstein 🤨
Alumínio é tão macio para derreter com a solda elétrica da pra fazer uma solda toda escamadinha
این الکترود و اون یکی اسمش چیه ؟
It appears that he is using the welding electrode to apply flux. What is he using for flux?
Ele tá Fazendo é caca😂
Ele tinha que ter usado o eletrodo na a solda elétrica era só dar um simples cordão kkkk
Não centralizou a parte quebrada, isso não vai encaixar no parafuso.
Bang,itu fungsi kawat las listrik buat apa? Kalo pake besi biasa sebagai pengganti kawat las listrik bisa?
It would be better if you don't have and use metalic brash.
Что у него за припой ?
Припой типа "старая проводка"))
Припой не главное. Главное это в качестве груза; на алюминивую крышку положить аоюминивую головку. Это конечно шутка. А сварщик спец. Нужно чувствовать прогрев алюминиевой детали; чтоб не потекла от перегрева. А хаотичными движениями припоя сбивает оксидную пленку на крышке.
but how come does gas welding work with a co2 gas. co2 is neither oksidizer or suport combustion like oxygen does
¿que gas usa: acetileno o propano?????????
E visto muchos vídeos soldando aluminio
Y no utilizan.fundente
Voy a intentarlo
Porque creo que el fundente hace todo lo contrario
Those are aluminium rod
Amazing
Do you mean you used LPG + O2? Oxygen, not CO2.
Bom dia solda na TIG fica perfeito.
НЕ АЛЮМИНИЙ, А ДЮРАЛЬ.!!!
Não sei não, em 40 anos de oficina nunca vi soldar alumínio com oxigênio, ou os tubos tem outro tipo de gaz quê não é falado?
Bengkelnya dmn bang?
Because that’s braising not welding…
You need some good aluminum flux.
Parabens
Itu co apa o2?
co2 LPG !
Please send me details about the alluminium brazing kit price details
Esa tapa era mejor buscarla en chiveras.
gas LPG nya bisa untuk ngelas kawat jemuran yg biasa di pakai untuk las acetylene gak bang?
What are you talking about? That part he ruined is aluminum.
انا لحام ولذيا خبر. في التلحيم في النحاس والحديد والالمنوم. والفونت الامر يعتمد علي السلك التلحيم. وكيفية أستعمل الشليمو
ich glaube kleben wäre besser gewesen als der Pfusch
Muchas lampra manipulando la pieza que vas a soldar
Sem limpeza do material,deve ficar bom mesmo. Essa solda não vai aquentar.
