dumb O2 sensor question, installing the bung on exhaust pipe?

Do you drill a small hole into your exhaust pipe so the sensor takes a reading of the exhaust gas? I assume that is how it works! I guess you would drill a hole the size of the sensor tip and then weld the bung unit that holds the sensor over the hole that you just drilled. Never done a PC package before and wanted to make sure I'm doing it right.

Once you have a bung take it to a welder that can do stainless steel and he will take care of it for you. When i did it i think i drilled an 18mm hole and welded the bung on. Then you just screw the o2 sensor into the threaded bung. I had to make a spacer on my lathe so the o2 sensor didnt sit so low in the exhaust pipe and restrict the flow too much.

Lots of YouTube videos on how to install an O2 bung
