I am going to weld in a new section in my exhaust y-pipe to get the front driveshaft off of it. Question is do I need to disconnect the truck's battery before welding the pipe. Using a mig wedler.

yup!
I would--I welded hundreds of times on cars and trucks with no problems--then one time I welded some new metal on the tailpan of my van under the rear doors--after I was done,I started it up to move it out of the garage,and I heard a loud squealing noise coming out of my subwoofer box--my 300 watt amplifier went up in a cloud of smoke!--didnt fry the speakers or the radio,but the amp was TOAST!---this was with an arc welder,but the mig is basically the same ,I would definately disconnect the battery--I was glad my van didnt have a computer in it,or that might have been cooked too....
--I've seen others blow headlight and tailight bulbs out while welding too,and I think the HEI module wont like the voltage surges either...

Get a good ground and it's not necesary. I've never unhooked a battery on any vehicle I've welded on. Welded on quite a few too. Computer and non-computer. Obviously not a big deal if ya wanna disconect it anyways though.

Personally I will disconect the battery before welding on any vehicle
For the amount of time it takes , you would really be pissed off replacing electronics ($$$) because of a poor ground situation
I have not in the past and been lucky , but a few guys did it on their pulp trucks and paid the price (no waranty coverage , comp. rats them out at the dealer)
Better safe than sorry.
