Topic tags/keywords: help spring bolt solder

Hey guys! I’m Leo. I’m new to the forum.

I have been in desperate need of help to permanently attach this spring with this bolt.
It needs to be a permanent bond between these too. I know it’s two kind of metals so soldering it might not work, right? And epoxy might not hold permanently, right?
The spring will be used with the bolt to go in and out of a piece of wood so it needs to resist the twist pressure.

If any of you guys could share your expertise I would greatly appreciate. Thanks!!!

I would weld them together or use silver solder. Silver solder will take a lot of heat unless you use a tig welder then you can localize the heat effected area. From the picture I’m seeing a steel spring and a stainless screw. If that is correct then a weld will be the best method, I would prefer tig welding it but a mig weld would be okay to. Either way you will need some 309 welding wire and some Trimix welding gas. That’s is how I would go about attaching the two. Any way you choose don’t quinch the work piece it will screw up the spring and the weld let it air cool.

Thanks for the reply. I just have to make sure the bond is easy to do fast and cheap since this will be needed to be repeated hundreds of times. Also I can’t have any residue on the side since this will go inside a tight fitting whole. I’m considering welding it but I think gluing would be easier but I don’t know if there is a glue fit for this. If there is i’d prefer gluing since that’s a much easier and more of my level method. (I don’t do much welding so if I can go about not doing it it would be better.)

Thanks

Welding is the only bond that won’t fail.

Have someone weld it. They probably won’t even charge.

I’m sure it’s obvious but put a big heat sink on that spring or the heat could ruin it.

Instead of a bolt, could you use a piece of all thread that would screw into the spring?

- jbay

This is the first thought that came to my mind as well. The only thing I’d do different is to thread and glue a nut 1/4” from one end of the threaded rod. Then the spring could be glued or brazed to that 1/4” protrusion.

If you don’t have a welder, find a friend with something like this:

Use it to get the job at hand done, then keep an eye out on CL for a nice used model for cheap. It’s like a hot melt glue gun, but for metal :)

For what you are looking at doing, you don’t need as big of one as shown above – a little 90A model that runs on 120v would be more than enough (like this one at HF for under $100).

Cheers,
Brad
