Grind Your Welds With Pride, If That's The Way You Do It
To grind or not to grind? What a question! It all depends on what you’re really trying to show, and in the case of welded joints, I often want to prove the integrity of the weld.
Recently, I wrote a piece in which I talked about my cheap inverter welder and others like it. As part of it I did a lower-current weld on a piece of thin tube and before snapping a picture of the weld I ground it back flat. It turns out that some people prefer to see a picture of the weld bead instead — the neatness of the external appearance of the weld — to allow judgment on its quality. Oddly I believe the exact opposite, that the quality of my weld can only be judged by a closer look inside it, and it’s this point I’d like to explore.
So dear soylentils, do you even weld and if you do, do you grind your welds?

A penetration weld on steam pipe is structural and doesn't need to be cleaned. For a TIG welded UHV vessel, the internal welds will be acid pickled and external welds dressed and pickled.
Fighting talk. When's the SN weld-off?

I didn't say good, just pretty fair. I figure good for an amateur would be able to pass for a pro at one specific type of welding, say stick on 1/16-3/8" mild steel, and have lesser abilities in other areas. I couldn't pass for a pro to anyone who knows what they're looking at.
My rights don't end where your fear begins.
