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

Click For Summary

Discussion Overview

The discussion revolves around methods for joining a thin strip of stainless steel mesh to create a cylinder for use in a "Y" type strainer. The focus is on exploring non-welding techniques suitable for forming a disposable filter that maintains water flow without obstruction.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that soldering might be the only viable option but requests more context to explore alternative methods.
  • Another participant mentions the need for a seam and proposes the idea of oversizing the mesh and using a welded strip metal to close the overlap, while expressing concern about impeding water flow.
  • A different participant raises the possibility of using brazing or spot welding as alternatives, providing links to resources on brazing stainless steel.
  • Participants discuss the characteristics of the strainer and the filtration requirements, noting that the current options available do not meet the desired micron specifications.

Areas of Agreement / Disagreement

Participants express various methods for joining the mesh, including soldering, brazing, and welding, but there is no consensus on the best approach. Concerns about maintaining water flow and the disposable nature of the filter add complexity to the discussion.

Contextual Notes

The discussion highlights limitations regarding the specific joining methods that do not impede water flow and the challenges in sourcing appropriate filtration materials under 800 microns.

Who May Find This Useful

This discussion may be useful for individuals involved in engineering, manufacturing, or applications related to filtration systems, particularly those seeking non-welding methods for joining fine mesh materials.

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.
