maximum amount of time to complete a weld
(OP)
Do any of the North American codes state the minimum amount of weld that needs to be deposited on a pipe joint before it can be left overnight? As well, do any of the North American codes state a maximum amount of time that a weld can be left without being fully completed? Let's say a welder is eighty percent complete and an emergency comes up, can the weld be left for a few weeks before it is completed or is there a maximum amount of time that it can be left uncompleted before it must be cut out?

But a purge cannot be left running(for practical reasons) for even a few hours. Preheat cannot be left "on." Weld rods (GTAW) wires or FCAW spools cannot be unattended (rust and accountability.)
7018 SMAW wires cannot be left out of the oven for more than 4 hours.
There are many reasons you need to finish welds - some related to time. Most for practical reasons of construction ans accountability.

What code states that rods in the oven should be consumed within a specified period?

Downhand: AWS is one of them. It's not necessarily that they should be consumed within a window, but rather that they should be consumed or returned to the rod oven within that window, 4 hours being typical.
