Could you use one of those welders made for welding wires onto Lithinum Ion cells?
Search for "battery spot welder" on ebay or wherever

Thanks Chris Lot of nice things there in Ebay. Problem is minimum 9 pages to chose from. I think I will chose something over USD50. /johannes ? ? ? ?

1) If you using EDM to remove tap you broke in the mini lathe it is related.? 2) Now if doing machine using EDM and not using a mini lathe it is not related? I only want to tap removal that mini lathe broke Dave

A spot welder would work, I think…I am assuming the 2mm here is diameter and not length :-)
Make your own??or buy one, Harbor Freight sells their 240 V one for $160… ? ? On Mar 19, 2024, at 9:20 AM, Johannes <johannes@...> wrote:

Johannes,
What you need is an old (non-working) microwave oven, and about 6 feet (2 meters) of very heavy copper electric cable.? Remove the power transformer from the microwave and discard the rest of it.? All you
need is the transformer.? There are several articles on ?“youTube” about how to make a very nice and simple low-cost spot welder from these basic materials.? As spot welders go it is a lightweight version but should work perfectly for your purposes. ?Happy
welding.

If soldering is an option strengthwise, but the issue is heat, then you might want to look into resistance soldering. It runs a current through the metal and the heat is very concentrated to just the point being soldered. It is popular with model railroaders working with small delicate pieces. Not cheap by soldering standards but cheap compared to welders. If you look around there are also some DIY articles.

"you might want to look into resistance soldering. It runs a current through the metal and the heat is very concentrated to just the point being soldered. . . . Not cheap by soldering standards"
I'm wondering, could you use a soldering gun for this?? They essentially use the same method. There's a transformer inside the handle that turns the 110 v. current into low voltage, high amperage current that runs through the copper tip and heats it.?
So you could connect two cables where the tip connects and attach their other ends to the work. That would run the high amperage current through the joint. The cables would have to be fairly heavy so they wouldn't get hot themselves, but I don't know how heavy. (Perhaps speaker cable would work here. It's heavy gauge supposedly for the best sound quality).
I use a Weller soldering gun (the same one I've used since getting it for Christmas at age 12, so they're pretty durable!)? That's 100 Watts. I don't know the wattage you need for resistance soldering, but if a single soldering gun weren't enough, you could hook up several.

I occasionally use a soldering gun when I need heat beyond the typical electronic soldering iron.? I have also used a resistance soldering unit.? Resistance soldering is MUCH better than a soldering gun because the heat is quickly and efficiently developed within the parts.? With a soldering gun, you still have to depend on heat transfer which can take a long time and end up with more of the part heated.? I think the role of a soldering gun for soldering mechanical parts is merely one step above a conventional soldering iron
However, you can get soldering irons with HUGE tips that can get more heat into the part much faster than a soldering gun.? And for some things, such as soldering small brass parts on a brass model railroad engine, speed is important, or everything heats up and other parts start falling off.? Today, most use resistance soldering, and some might use solders that melt at different temperatures and assemble things in a sequence.? But I have seen assembly line photos of people in Japan in the 1960's building small brass model railroad engines that were soldering tiny parts with these giant soldering irons.? That is how they got a local area real hot real fast before the heat could significantly transfer everywhere else.

Thanks to you all boys. I have got many solutions for “welding”, and I am thinking and reading. No solution is made yet. Attached is a picture of what I have to made min 33 of before Christmas this year. It is 15 cm long. All metal is 2 mm galvanized rod. To made a 1 mm hole is not complicated, just it take time. To make a 1 mm tap is very easy, I have a clockmaker lathe and good cutting tool. ? To info: this is a “Ratt-kjelke” , it is Norwegian word for “steering wheel sled” Very popular 70+ years ago. However, not made for snow, only ice! You see it has a brake. Terrible toy for children, ?now I think it is forbidden, maybe you can find it in a museum of horror. ? ? /Johannes Mexico ?

I do see on a welding group where have tell the person a microwave transformer is not big enough for spot welding.?
It takes thousands of amps to weld metal.
YouTube videos work on film only.?
It can stick the metal but will not hold.
You do spot welding with fluxcore?

I bought a resistance soldering machine powerful enough to do
gold soldering for about $35 from an Ebay seller and it was less
than 20 miles from my house.?? I can solder brass tabs onto a
clock bezel fast enough to not discolor the outer surface of the
part.?? If you back off the carbon electrode until it arcs, it
will burn a hole through a hacksaw blade in seconds.?? Quick way
to make 8" long blades for a tiny vintage power hacksaw.

Just do a Google image search for, "resistance soldering unit".? You'll see lots of them + instructions on how to build one. I got mine at a garage sale, from somebody who used to make metal eyeglass frames. The innards are basically just a fairly hefty low voltage transformer & a small variable auto-transformer? to control power level.

Here are some offerings from Micro-Mark who caters to hobbyists:
And you can go to YouTube where there are MANY videos including so for how to build one of your own for low cost.? The two methods used for heating is to attach a lead somewhere on the part and then use a single point probe.? The other is to use tweezers where each tip is an electrode.

i SEE? SOME HOWRO RESISTANCE WELDING? UTUBE?? BUT? SOMETHING? HAVE? TO? BE SAID?
Professional welders have three setups
1- Squize is a short time not to deform the object
We must not weigh for a long time on the Welding Pieces
2- Heat heat 'you have to modulate the voltage to vary the heat; Easy to do with a dimmer
?
3- Hold is that you have to hold the piece after
having welding so as not to make cold welding if it moves a can after applying the heat
ALLE? THIS? EQUIPMEENTS? DO NOT? MAKE? PERFECT? ?JOB? IF? YOU? ?DO NOT? KNOW? THIS
