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.
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
🙏🙏👋
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.
Hi, I'm from Québec Canada. I like this video. I'm glade to learn this trick. Thanks
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 😊
To solder stainless steel, brass, iron and common cans and also copper, just use phosphoric acid, which is used in culinary recipes.
👍
Esta solucion la conozco hace ya 40 años.
Exelente !
Lembrei meu pai ferroviário usava zinco com ácido sulfúrico pra soldar.qdo eu era criança. Saudades obrigado amigo pela lembrança.
Obrigado por assistir !
Mi padre preparaba esa solución para limpiar y soldar. Gran recuerdo de mi infancia.

Tę metodę z chlorkiem cynku stosuje się od setek lat. Co prawda ostatnio się odeszło od samodzielnego przygotowywania tego związku, bo w sprzedaży są gotowe pasty zawierające chlorek cynku.
Jasne, a poza tym podobnie działa odrdzewiacz Fosol.
Great technique, thanks (from Geoff in Birkenhead, England).
Great lesson. Greetings from New Zealand

Gracias por este truco máster. Saludos
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.
Muchas gracias por el dato mi viejo!! Ayer justamente quería reparar una rejilla de acero inoxidable y no pude, así que este truco me viene al pelo, mañana lo pruebo!!! Saludos desde la Patagonia Argentina!!!
A la orden ! Saludos querido !!
excelente el video ahora conozco algo nuevo.

Thank you for sharing useful information 🎉
Thanks 👍👍
Nice technique, lots of items I have in my workshop will become live again 😂. Thanks from Pakistan
Good video. Thank you Slovakia, Zlate Moravce
Aluminium solders fine, need more heat and you need to scrape the surface harder with preferably a copper tip. Iron plated tips get contaminated
Saluti dall'Italia. 👋👋
Grazie 👍👋
Bonjour, cela ressemble plus à du chrome qu'à de l'acier inoxydable mais le résultat pour la majorité des inox est sensiblement identique.
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.
Excelente dica, 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.
Genio como siempre!!!!!!!!!!!!!Abrazo desde Argentina
Hola, muchas gracias

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.
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.
Very interesting. I live in northern California
Thanks for watching !
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.

Thanks for the feedback 👍
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?
Qué buen dato ! Gracias !
Me había entusiasmado con el Al ... pero bueno ,todo no se puede.
Gracias Saludos !!

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.
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.
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

What was so cool! Thanks!
Sehr aufwendig. Bei Edelstahl nehme ich einfach Hartlot mit einer kleinen Lötlampe.
Could it also work with muriatic acid?
Yes it's called Zink Chloride, you can buy it in most welding suppliers, and yet again this is not welding it is soft soldering.
Right ! google translator does not know the diference !!
@@Repairman10169 Maybe it's Chinese; they always call soldering....welding!
Orthophosphoric acid (H3PO4) works best as flux on stainless steel.
Must clean well the solder tip and the work area when finished.
Yes right !! 🙏👏

what about silver?
how to solder a thin silver plate?
i mean 1 of mobile battery point side is silver (Aluminium)
which is spot welded, those who were are not afford spot welder
any trick for them to solder on silver?
A file and some silver solder can work wonders. Plus, solder won't stick if the part isn't getting enough heat.
👌👋
Very nice, thanks for sharing! 🙂
Thanks for the feedback !
The video connector (BNC) you show at the end is crimp-on, and should never be soldered. Impedance is very important in video. Soldering will alter the impedance, typically resulting in video degradation.
Yes your right
@@Repairman10169 😁
Yeah, the BNC was killing me. 😄🍻
@@jessebob325 🙂
Pour l'inox et les métaux difficiles, il existe de la soudure avec un flux spécial. Ça fonctionne très bien.
when I was a grasshopper soldered SS used phosphoric acid as flux and used silver lead alloy
You were a grasshopper? Was this in a previous life?
Wow zinc chloride works like magic! I can finally solder my nuclear enrichment reactors reliably now!

Stainless steel, in the same league as aluminum. The resistance to soldering is for the same reason, a nearly impermeable oxide layer that protects the metal underneath from corrosion.
100% right
thanks from Belgium...

The stuff from the old times , greetings belgium

That is a pain in the, you know what! I use ferric chloride. I brush some on, wait a couple of minutes, and wipe it off. Then, I use acid core solder. I bought a bottle of it for about 17 bucks on amazon. Acid core solder at ace hardware was about 7 bucks. HCL is a little harder to get your hands on and a lot more dangerous. Not to mention screwing around with the battery. Works like a charm on 309L through 316. Use it all the time.
What about your flux applicator brush?
It's what my Grandfather used to call killed spirit, I suppose I'm one of only 8%.
Our metal work teacher showed us how to make killed spirit at high school in the 70's
Sir,
Readymade soldering solution is available in the market
Thanks for the feedback !
Scratch the surface to remove the chrome, coat with zinc chloride and sollder, much simpler

E para alumínio, como fazer?
Per fare la brasatura su alluminio invece di usare lega di stagno e piombo si deve preparare una lega si stagno puro e zinco.
To solder aluminium, essentially you should do the same procedure, but the workpiece should be submerged in oil. The problem with aluminium is that it oxidises instantly, and the oxide is not wettable. To prevent this, put your workpiece in oil, scrub it with brush or sandpaper, apply the flux (*), heat up, add the solder alloy and melt it.
(*) Of course, the flux must be in the form of a paste, not aqueous solution. Interestingly, flux may not be necessary, because it is supposed to remove oxide, which - in this case - can not form in oil bath.
Se ve bien. Yo lo hacia usando ácido ortofosforico
Si funciona también con ácido fosfórico. Saludos
TOP, gostei muito mas, me parece que, esse ácido, é produto controlado difícil conseguir comprar.
Mira que nps cuesta aprender, tantos años peleando con el estaño y el soldador, con esta "brillante idea" me resuelbe un monton de roblemas "aparcados", gracias,,,,,😎👍👏👏👏👏
