Re: "welding"

 

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'd like to see some pictures of these resistance soldering machines. I am really interested.

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.

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.
