[@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.

[@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

[@user-vx4hp4nz1u]

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.

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.

[@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.

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...

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.

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.

[@klave8511]

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?

[@AndrewCampbell-ut6jk]

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.

[@DinkyDoughnut]

@@VitezslavNosek 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.

[@aeroearth]

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.

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.
