How Can I Join Stainless Steel Mesh to Create a Cylinder?

[MechEng91]

Hi I need a way of joining a very thin strip of stainless steel mesh to form a cylinder.

It forms the 300 micron mesh cylinder that sits inside a inline "Y" type strainer.

The one i have currently doesn't seem to be joined by adhesive but by a heat crimp or sum sort of non welding/soldering method.

Any ideas

Cheers

i think soldering is your only shot my friend, but if you gave a better insight as to what its needed for maybe we can come up with some other method.

Ok the strainer is much like the one above and you can get the mesh in steel, alumin, ss etc. Its used to filter water being injected at pressure into some jets for underground coal dust suppression. We were looking to by the filter mesh with 300 micron and 100 micron filtration. It may take more to manufacture however currently we haven't sourced anything under 800 micron in filtration.

So in essence its just a throw away filter of sorts. Just need a way of forming a cylinder without soldering this very fine mesh. It shouldn't impinge the flow of water, hence no solder.

Unless you can deep-form a perforated sheet into a cup, you would seem to need a seam...

Given that it will be disposable, can you over-size it and close the overlap with a sandwich of welded strip metal ?

That is a very good idea Nik however i don't want to impinge the flow of water through the strainer. There is a seem on the one i have currently however I am not quite sure if it stuck together by adhesive but blowing air through the seam it doesn't seem to be.

I had a similar question but your advice on the perforated sheet has helped greatly.

Brazing may the way to go unless one can spot weld.
