It is possible to weld it, but it won't come out again. If you need a new one in the future, that part of the exhaust system will need replaced.

Before having it done, make sure that is where the leak is coming from, and as far as the computer, that sounds like a problem between the computer and the scanner, not the O2 sensor.
