Stainless steel mesh bonding to mild steel plate

Me too...

That is some small stuff you are talking of, and if the material were larger I would use a good stainless welding rod... I am guessing some press/tack welding process would work with a powder flux...There is not enough information, really... How thick is the mild steel, how large is the whole structure, what are the applications/forces it will have to survive, etc.. Is sandwiching it a possibility???

You are talking about the tch they use to make fine well screens. Id contact UOP Johnson and see if anyone there can give advice. I use these fine screens and they are mild steel frames with 416 stainless mesh Usually 100 microns at the small end , up to 20 slot at the upper end. I have no ide how they are tck welded but I always thought that it was by a method where the steel frame was the anode and the mesh was the cathode and it just fused by arcing. I dont really know though.

Maybe it's just a simple soldering operation.

Only silver solder will bond to stainless... To my understanding...

You could be right, and maybe the higher temps involved in silver soldering wouldn't work here.

hello ,i am sorry i couldn't answer you question .do you know some websites about steel mareket and iron ore market?thanks
