Problem soldering stainless

I'm in the process of soldering a bowl to the stock pot lid. The solder is just rolling on top of both of them. I've cleaned, sanded, and fluxed. It just won't stick. What do I do? Any tips? I've done researched so don't jump all over me for not researching.

Most deff flux and to low of heat you don't want to color the stainless "get it to hot " or it will make it structurally unsound but the stainless will take more heat than copper and try heating smaller area and rather than large with the exception of preheating the are to be tiged / brazed

I'm also new to soldering stainless, but I've had some success. Having the right flux was critical. Another recommendation that helped me was to flow solder on both parts before attaching them. I was attaching a copper flange to a stainless bowl. I flowed solder onto both pieces separately, then re-fluxed and heated them until the solder melted and they joined together. Without pre "wetting" the pieces I still had trouble getting the solder to flow onto the stainless, even with the correct flux.

im new to soldering ss but Ive seen some good videos on here. from what I learned, soldering is like stilling. when soldering you slowly heat up the SS like heating (wash/bolier). to the point where the solder begins to flow, (getting output). using the right flux. I use harris stay clean liquid flux. (fermentation)
so heat up the steal slowly, put the solder around your fitting. flux well, heat the outside area and work your way in . in one video ive seen the guy stops the heat up and adds flux for the second time half way through heating. I did the same. the key is not to heat the ss to fast. basically go slow with the heat until the solder flows. always remember to heat the thickest piece (ss copper). let the heat transfer to the thinner material. heat and just lets it flow
my results. I got a great solder other than a pin hole! DOH! easy fix. ive got 2 more couplings to solder up. the strength of the solder seems to be pretty strong. only time will tell . gl
