This video is really great! It gives a very useful stainless welding tip and probably a secret that many users don't know.
I was always wondering how to get a decent conductive connection otherthan buying a spot welder.
A very professional and useful way to weld stainless steel

ZincChloride flux is obtainable in the UK under the Baker’s Fluid brand. It should be washed off after soldering because it will continue to corrode the base materials. It should never be used on electrical joints as it could wick up inside the wires and lead to unseen corrosion. The proper flux for stainless steel is Phosphoric Acid . I suggest that the two bits of “Stainless” soldered together were actually chromium plated and you can solder this with the flux shown.
Thanks for your feedback 👍
how many percent phosphoric acid?
@@Adam-d7k I use 85% phosphoric acid and it works on copper, stainless steel, brass and iron.
.
Not to strong I would say 20-25% even a bit lower. If it's too strong it will eat your copper soldering tip very quickly. Use solder with the highest tin content you can find. To much lead is no good. I use 94% tin 6% silver to soft solder stainless and it works well
Thanks! I am from India. Now 70 +, in my teenage days I used to watch a Kerosene Stove repairer near my house doing soldering jobs. I used to collect old Dry cells, preferably of Estrella make, and give him. He used to give me few Paisa, enough for me to buy a Candy or Ice cream. I have seen him using the Battery case as seen in this Video while soldering. Although he used a soldering rod with a heavy Copper tip, which he used to heat with a Kerosene burner. Now I know the exact reason for the Zinc case.
Thank you very much for taking the time to share your memories as a child, i realy appreciate !!
Oxigen reacts first with Zn and it is consumed so remains nitrogen from air as inert gas to protect the soldering zone. HCl clean the oxidazed surface of the solded metal. In cas of aluminium is different, Al reacts with oxigen before Zn and Al2O3 is more compact.
To solder stainless steel, brass, iron and common cans and also copper, just use phosphoric acid, which is used in culinary recipes.

Cómo se usa el ácido fosfórico, se untan en la superficie a soldar y luego se pasa el soldador?
Well now. Thank you very much. I am retired electrical tech and never in last 45 years have I soldered stainless. Now to find some HCL. Hilo, Hawaii
🙏🙏👋
HCl = muriatic acid, something you can find in hardware store or pool supply stores, commonly sold to people to balance out the Ph in their swimming pool.
Also sold as brick cleaner. Muriatic acid.
Buen truco... para los que no quieran hacer todo el proceso, pueden usar en su lugar ácido fosfórico, para soldar acero inoxidable con soldador y estaño... hace años que lo uso... una cosa a tener en cuenta, es bastante corrosivo con los metales y desprende vapores dañinos al soldar... se debe limpiar la superficie después de soldar, así como la punta del soldador...
Exacto, ácido fosfórico funciona perfecto, como en algunos lugares es difícil comprarlo he puesto está alternativa.
Saludos 👋
?
Acido fosforico? Cuanto %?
@@Adam-d7k Depende de la superficie que vayas a soldar, pero para soldaduras pequeñas, con mojar la punta del estaño en el ácido (una gota, vamos...), es suficiente...
Lo aprendí hace muchos años, cuando trabajaba en los talleres Victoria, en Ferrocarriles Argentinos. Muy buena explicación 😊
For Al you must put mineral oil and scratch the surface with sand paper and you can do soldering process under oil, after, clean oil and that is.
Thanks for the tip 👌🙏👋
@@TREE3-ph4sr That can happen with any molten metal. Air causes airbubbles that's why Flux or a gas shield is used in welding. When the metal is hot all the air is pushed away but as it's cooling the air tries to rush back in so a Flux keeps that from happening.
@@Useruserusername790 air causes air bubbles? A little lol is deserved, but you are both right, that the air oxidizers. So scrape through the soldier. And I was going to try to sell my secret to 10169. LOL. Oil? OK, it is worth a try.
@@cliffontheroad "that the air oxydizers"? Mofo I was explaining how a gas or a flux keeps Oxygen out of any liquid molten or whatever. The material doesn't matter. Y'all really think it only applies to Metals. Think of your skin as a flux to keep oxygen out of your insides. Terms are just Terms.
Aluminium can’t be soldered ‘as is’ because it reacts with oxygen in the air to form a protective layer of aluminium oxide which is non-metallic (it’s the same as alumina ceramic!). Sanding it breaks through the very thin layer of oxide to expose the metal. Applying the oil isolates the metal from the air and prevents re-oxidisation allowing the solder to alloy with the aluminium and ‘wet’ it. But the oil must be applied immediately the sanding is ended as the aluminium re-oxidises very rapidly.
Mi padre preparaba esa solución para limpiar y soldar. Gran recuerdo de mi infancia.

Aluminium solders fine, need more heat and you need to scrape the surface harder with preferably a copper tip. Iron plated tips get contaminated
Merci pour l'astuce! Elle est peut-être déjà très connue, mais profane que je suis je ne la connaissais pas!
Está tremendo eso,estoy ansioso por probarlo

Hola, muchas gracias
Tak pájení je svařování?

Not quite cause solder is a very soft form of metal. Weld could be a fusion if the two will and the introduction of an additional metal where required, either one of the two is welding. Spot welding is an example of fusing the two metals together.
Yes! I didn't know this welding trick until I saw your video. Thanks for the great video.

Excellent video! Really appreciate the time taken to create useful content here. The flux from basic ingredients was very useful. Also, the helpful comments by other viewers is very useful, too.
Thanks, really enjoyed these ideas!
60/40 lead solder or 97/3 Sn/Ag solder are OK for electrical joints and low stress mechanical joints. The 97/3 solder is some 50% stronger than 60/40 solder.
If using a zinc chloride flux such as Bakers Fluid on mechanical joints, I neutralise with sodium bicarbonate solution.
High strength joints on stainless steel can be done using silver solder 55/45 Cu/Ag. Use proprietary flux which contains flouride. Have to heat to red heat, usually with a butane torch but oxy acetylene can be used using care not to over heat.
Akuminium can be soldered using proprietary alloys such as Lumiweld, which require no flux at all. However aluminium soldered joints are not very strong. For strong joints have to AC TIG weld them.

Cortas a trozos pequeños la vaina de una pila alcalina y la sumerges en alcohol 90º y con esta solución la aplicas antes de soldar estaño con cautín, es correcto? buen vídeo, saludos desde Punta Umbría.
No es ácido clorhídrico, si activas los subtitulos ahí explico bien.

@@Repairman10169 siiiii ya lo hice, gracias amigo, no sabía de esta función, saludos.
Boa informação, obrigado. Saudações do Brasil.
I am from S. India and belongs to an industrial town called Ranipet ( about 130 km from Chennai on the Chennai to Bangalore highway). You have mentioned HCL acid 50 % is it that much concentration needed ?. Please enlighten me on this point. Rest of the video is so informative and will help me in meddling with like materials while soldering. Also let me know the solder wire's composition : is it 63 +37 one or 60+40 one.
Even Alkaline batteries are surrounded by Zinc. I know this because I make my own stripper, Zinc Chloride, by cutting up pieces of Alkaline batteries. By putting them in hydrochloric acid and letting the Zinc be completely eaten away for about 3 days. I like to have a good dose of Zinc in the mixture, it makes it thicker and more stripping.
"Zinc-Carbon" Saline batteries are impossible to find in stores, at least in France. You have to order them from China, and they cost more than Alkaline batteries, the height of it !
Because Saline batteries are much less effective than Alkaline batteries. They should never even exist anymore.
I remember at the time, we could still find Saline batteries on the shelves, they were the cheapest ! But in 2024, it's long since over, all batteries are Alkaline, even the cheapest batteries. Which does not prevent them from also being surrounded by Zinc.
But there is no small bar in the middle that can be used for arc welding, it's a shame. Forced to order the batteries in China for a huge price, while they are batteries from another time !
If you're in France there's more zinc than you could shake a stick at. House rain gutters and down pipes are made of zinc.
In the US, another zinc source is from pennies made after 1982. Just file off a little of the copper cladding. After putting the penny in HCL and letting it react, you end up with zinc chloride and an empty copper penny shell.
Interesting !!
Nice technique, lots of items I have in my workshop will become live again 😂. Thanks from Pakistan

When you fuse it it’s best to know what grade of stainless it is because 304L isn’t the same quality as 316L etc
Thanks for the feedback 👍👋👋
I'd heard it was 93.25% didn't know the trick. What a relief.

Que le agregas después de deshacer el zinc y en que cantidad ?
I am in Jamaica and years ago an American invented a rust remover that allowed me to solder stainless steel. I did not even use a soldering iron. I just heated a piece of rebar on the stove top, applied it to the top of the cold fridge top and the solder instantly formed a thin skin on the surface! I often wondered what became of it.
Muito interessante, parabéns pela dica👍👍👏👏👏
Obrigado

Muito bom o seu vídeo!Conheço outro procedimento, para soldar peças de aço inox, mas exige o uso de Ácido Fosfórico, que é bem difícil de se obter em casa. Procuro por um livro, antigo de preferência, que ensine os detalhes de fabricação de GAXETAS DE COURO, vedações tipo copo de couro, para pistões hidráulicos.Algo tipo um manual antigo da Editora Labor, que ensine como fabricar essas gaxetas. Você conhece algum, poderia me indicar? Pode ser em Espanhol, não sei escrever, mas leio sem problemas, em seu idioma. A propósito, sou de Juazeiro/Bahia/Brasil.
Almit’s super-activated rosin flux actually works pretty well on stainless and other very hard-to-solder metals. - But good to know about zinc chloride and phosphoric acid from the comments. As others have said though, you gotta be careful to wash it off thoroughly afterwards to avoid corrosion.
Great point, thanks for sharing! 👌👋👋

Once a batch is made how long will it last?
I assume that after 30 min reaction that afterwards you can close a lid on the mixture.
What did you add after dissolving the zinc with acid? Water?
thanks from Belgium...

Very interesting. I live in northern California
Thanks for watching !
You are so correct I didn't know to make that from a battery
I did know about buying a $19 bottle of zinc chloride from Amazon
Thank you very much ❤
Thnaks to you for watching !!
Did anyone try this.
I know that the acid is in excess, it cleans the dirt off the surfaces before soldering. But the Zinc ions, do they have any effect in all this.
The original “soldering fluid”, “bakers fluid” or “killed spirits” is zinc chloride, from decades ago. When soldering to zinc plated (galvanized) surfaces you used the acid directly, diluted by some amount I don’t know. It is corrosive so needs to be properly cleaned after soldering. The excess acid may be unnecessary, probably better to dissolve some zinc in HCl till it stops reacting and there is some zinc left, less corrosive afterwards?
Thank you very much for showing how-to re-cycle and convert Zinc metal into its' Chloride form.
Cant you just buy Zinc Chloride Solder Paste?
Is it now more expensive for some unknown reasons?
I just use a standard (everywhere) flux named: "ZincChlorideFlux" that's sold in a small re-seal-able metal container that has still lasted me since I was a teenager last century when I learned to solder and weld.
A file and some silver solder can work wonders. Plus, solder won't stick if the part isn't getting enough heat.

Why solder a crimp on BNC connector in the first place? Does this work in reality? And does it work on aluminium aswell? I'm no chemistry whizz, but I am curious if it works.
