Just do like Swamp says. I did and it works great. Your kettle ring just slides right in nice and snug without any welding.
I tried using some oven gasket(which worked pretty good), but it kept falling apart on me.
Oh yeah, I do notice that if I use another lid(other than the original) it does pull up a little bit when I take it off.
