The black paint if for YOUR welds :-)

I only have to worry about weld quality if I send work out.

I DO screw up welds, now and again, but if I do, I grind it out, and
start over.

Even good professional weldors occasionally mess up. It's what they do
AFTER they mess one up that separates professionals from the hacks.

My Dad was a professional steam vessel weldor before WWII. In his job,
"mess up" meant ONE slag inclusion or bubble inside an inch thick weld,
which they X-rayed to inspect. Find one? Grind it out!

That is also typical of gas transmission lines :-)
