This video is really great! It gives a very useful stainless welding tip and probably a secret that many users don't know.

[@DinkyDoughnut]

I was always wondering how to get a decent conductive connection otherthan buying a spot welder.

[@nguyenhop]

A very professional and useful way to weld stainless steel

[@houstonceng]

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.

[@Repairman10169]

Thanks for your feedback 👍

[@Adam-d7k]

how many percent phosphoric acid?

[@miltonkawatak5659]

@@Adam-d7k I use 85% phosphoric acid and it works on copper, stainless steel, brass and iron.

[@richardbarber4444]

[@jamesrichards4859]

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

[@Chacha-c2b]

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.

[@gabipaduraru2004]

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.

[@alfreire]

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...

[@Repairman10169]

Exacto, ácido fosfórico funciona perfecto, como en algunos lugares es difícil comprarlo he puesto está alternativa. Saludos 👋

Acido fosforico? Cuanto %?

[@alfreire]

@@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...

[@Useruserusername790]

​@@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.

[@cliffontheroad]

@@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.

[@Useruserusername790]

@@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.

[@ianmathieson65]

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.

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.

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 !

[@johnking3234]

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.

Aluminium solders fine, need more heat and you need to scrape the surface harder with preferably a copper tip. Iron plated tips get contaminated
