what kind of metal?
I have two metal strips ( around 0.5 mm in thickness )
I have to join these 2 strips to make them one piece.
But i don't find a suitable, easy, permanent method to stitch these 2 strips.
what kind of metal?
about how big are the pieces is the joint going to be butted together on an edge? how long of a seam? is it decorative or is it a structural even though its thin? is it going to be tight tollerance or do you have sum fudging room.
Ya, i know these techniques such as soldering, brazing, welding. I don't favour to use these things because i have to attach 2 small parts. Its not feasible to do welding, brazing to small parts
Any ideas about some adhesives like feviquick, loctite which would permanently lock these 2 metals.
Dont worry, these are not supposed to take heavy loads. May be a load of 0.25 to 0.5N.
If you can clamp or weigh down the parts, however tiny, in position with some SMD solder paster where you want the solder, then just heat gently with the tiny flame from a soldering torch until the solder melts.
The surfaces need to be freshly cleaned, better still pickled in hydrochloric acid so they are spotless. Only put the paste where you want the solder, and only just enough for the job.
Those helping hand gadgets with adjustable crocodile clips work well.
Forget the glue. This is easy with some practice.
It works on small parts you can only pickup with the tweezers.
Maybe heating with a small soldering iron will work OK too.
Clean it, flux it, clamp it, heat it.
Super X3. 3600rpm. Sheridan 6"x24" Lathe + more. Three ways to fix things: The right way, the other way, and maybe your way, which is possibly a faster wrong way.
there are some epoxies that could work but to be strong the joint probably wont be very small. I've tig welded down to 0.010 in. but the soldering technique niel20 described would be your best bet. or if you dont feel comfortable doing it yourself you could find a jeweler to silver solder it for you.
