For the project I'm doing(axis movement controlled by pneumatics) I need to attatch two pieces of steel several times. It doesn't have to be a strong weld at all, It just needs to be there and stay there....

Would a certain kind of epoxy be okay for this, or will I have to weld?

I don't have access to an intricate welding tool / system, but could probably rent one....

Like I said, it doesn't have to withstand pressure, or hold anything in, it just needs to be there...

Thanks in advance....
Kthx, BAI

If it is small, and supporting nothing more than its own weight, epoxy may be acceptable. Otherwise, you may as well weld it.

It is quite small. 1/4" in width and only a couple inches in length...

I would weld it, but I don't have any experience welding, and as such, wouldn't know how to do it...

If you don't have welding experience, don't try it unless you have plenty to pratice with. Pieces that small are hard to set up, plus they will draw, and chances are you will burn them up before they are where you want them. If it's just for looks, JB Weld is the way to go.

Er...
Solder, duh.

Not as strong as welding or brazing, but its cheap and fast and better than epoxy.

is it asthetic, or structural? For some reason I'm getting the idea that this is a bipod.
If you can, use a nut and bolt. Otherwise weld it, then last choices for me would be soldering or adhesives/glues.
I'm weird, I know it, you don't need to tell me.

i would have to say pop rivets or jbweld for something that small.
nuts and bolts or stick welding for a piece of metal 1/4" wide is plain stupid.


1/4" = 75 pixels

1/4" NPT is not 1/4" wide
