Hello all I have a problem with rust on my welds. First off, I am not a welder. I had an experienced welder weld 1/4" High Pressure SS couplings into the bottom of my brew pot. It has been about two weeks since this has been done. Now at first I didn't think anything of it because I was busy finishing the rest of my rig, and I had heard that welding SS on SS shouldn't produce rust. I also heard than if there was rust, then it should not really cause a problem but it seems to be slightly spreading. What can I do to remove this or any general information would help. Thanks.
