I would do some destructive testing to see just how well the filler metal from the mig penetrated the laser cut edge. Laser cut edges (same as plasma but laser seems harder to burn through) have a coating on them and it can just about block any penetration in that area because the surface of the cut edge has nowhere to go when it melts. It might be worth a sample piece to bead blast or wire wheel the surface off the laser cut edge and do a side by side comparison to see what fails first, if anything. If you get the same quality test out of the cleaned edge as the un clean edge then it should be good. The .075 will probably deform before you have to worry about the weld breaking. The only thing that stands out is the laser cut edge. It's bitten me in the ass before I realized it had to get cleaned up for a prefectly clean weld.

If you want more detail give me a call, I dont feel like typing for an hour.

Looks good as it is though, should be trouble free.
