whats the difference between the t3 and the t4 flange?
T4 flange is bigger in all dimensions that the T3 flange. Some T4’s use a divided housing (but not all).

Yup … Main difference is just a bigger dia. all around
as in ID or just bolt pattern or both?..do they make t4 flanges to weld onto manifolds?
No clue about the weld ins … sorry
the bolt patterns are different and the t4 is bigger and can make alot more power on it unless you like the to make big power on a little t3 turbo and a little 1.6L 1595CC MOTOR LOL
