On the exhaust coming out of the engine, you will see the O2 sensor screwed into the pipe before the catalytic converter and then you will see one screwed in after.  I don't know the exact location for them but they look kinda like a spark plug with a wire coming out of the top of it.

Right after the air filter, way before the throttle body.

There is a chance that your temp sensor is the culprit on both codes. The temperature sensor is what tells the ECU how hot or cool the engine is and weather or not to keep the engine in phase lock loop, or choke, mode. If the engine stays in phase lock it will run too rich and the O2 sensor will not be able to compensate.

Marc,
this shows that the oxygen sensor on the left exhaust pipe before converter is bad,
And the front oxygen sensor on the right exhaust infront of converter is bad.

sounds like you know what you are doing, sometimes the codes have to be removed after repair, i'm not sure whether or not your vehicle requires this. If it is just a light bothering you try and clear the code and see if it comes back. Some Advance Auto or O'reilly has a tool to do this free of charge

Do i need to weld a new catalytic converter to my 2000 chevy blazer


First of all do you have one on there presently? This is what one does so if you don't have one it would be a good idea. A catalytic converter provides an environment for a chemical reaction wherein toxic combustion by-products are converted to less-toxic substances.A catalytic converter (colloquially, "cat" or "catcon") is a device used to reduce the toxicity of emissions from an internal combustion engine. You may just want to check your O2 sensor. I hope this helped you!
