I'm pretty sure your batt. has to be left off for quite a while for the ECU to reset.
but don't quote me on that...

around 20-30 minutes from memory.

When i had another muffler added to my car, they didnt disconect the battery. And theres been no problems.

I probably would just to be safe but

so ya reckon i should get it all ready to weld and take the terminals off and do the welding asap so the ecu isnt disconnected for long, prob 5 mins max?

I've only ever heard you're meant to disconnect the negative terminal, but when mine was done i dont think they disconnected anything cos everything was normal when i picked it up, no problems whatsoever.

Most exhaust shops have a special surge protector they just place over the battery terminals. All the technical material I've read at college says to disconnect both battery terminals before carrying out any welding. I wouldnt worry too much about the ECU resetting itself as it wont take long to relearn again.
