How to install a 400-mesh screen

The attached diagram shows the structure of the device; a mesh is placed on such a structural frame for filtering catalysts. How can the mesh be secured tightly to the device walls to prevent leaks? We are not able to carry out welding using such a process for now. The catalyst particles are very small.
A baffle can be welded to the upper part of the grating; this baffle together with the edge of the grating forms a groove, and the excess parts of the wire mesh can be inserted into this groove and pressed down to secure them in place
