Panel repair with mig

I saw a video of a chap welding in a new panel on a car. He created a flange on the old panel as opposed to butt welding and welded the seam continuously. .
I kinda like that idea. Or how about overlapping slightly and plug welding then using bondo to blend the two in. You could waterproof the back to prevent water from getting into the seam. Ant thoughts?

Neither. Both methods are for hacks. Look at my thread title " Some work" you can see how to properly repair/ weld in a panel

Theres all sorts of issues with both. Lets start with the flange. First and foremost it will allow water to get behind both pieces of metal and will rust, two, it looks like *** from the back side, three, its a hack method. Five, no one welds a continuous bead on sheet metal. If you do you might as well throw the panel out in the street and let a forklift run over it, it will be so warped.
The plug welds then bondo is just NONONO. Asking for rust and the bondo to crack. Those two types of repairs are the kind that gypsies do on rebuilders. Crap like that gives guys like me a bad name.

When I said continuously welded I meant a whole bunch of stitch welding. Looks like you do superb work. What is the reason for the notches and tabs in your panels. How do they come together. Butted up and welded?

Those are for Clekos. They hold the panel in place without clamps etc.
