This corner/section

where the two pieces meet at the side, the corners touch. I cut the
other two corners for a flush cut.....

Should I cut one side piece to make flush with the other for better
welding or will a good welder be able to fill that in for a secure
job?
Thanks

The first pair , you need to widen the vee a little , give the welder
somewhere to put some filler . The other pair should also touch at the
inside corner , and have about a 60° vee .
