Basically yes. the "good fit repair piece" can be mig spotted, to hold, then seam welded, to original steel, to inner piece and good fit repair piece all in one op. You should not have any "blow thru " holes to attend to and minimum grind back. Practise and get it perfect for your app and no grind back needed at all !!
Will do a mock up and post some pics, but every inch, even double row aircraft style.......18swg, bit difficult to cut and bend but strong and easier to weld.
I assume you have a sturdy bench with a good vice. Get a good pair of shears, relatively easy to cut ( for me at least, porrage and some years experience ) to line.
Some stout angle iron pieces for bending etc.
I am making ( or I was until the almera died etc... ) a metal folding "clamp" like I used to have access to, 10mm x 75 x 75 by 4 foot angle iron, 2 pieces, clamped flat and 5 holes bored to take tow bar ball size bolts, and one iron welded to vertical welded to 2 old car wheels.
So undo nuts sufficient to slide in sheet and clamp. The upper surface of the angle is "true" and level, so a "true and level to size fold can be made via correct size hammer and finisher etc.. Its not rocket science, a really handy clamp.
So bent sections can be made 3ft 6inch long, and say 4 foot wide/deep ( a good working height for me ) max, so make folds etc for body panels and sill repair pieces for the rustbucket of a fiesta.
Almera sill £70 each + vat, sod that !!
Max length I could make with small angle irons and bench vice was 15inch long and not very wide/deep.
From memory, sill vertical 15mm, 90 degree bend then 4cm wide, kick up 45 degrees ish x 4mm, kick down back to horizontal to allow for fold around curved part of sill and weld line about half way up sill.
Some horizontal repair bits where also needed to beef up sill and have good metal to weld corresponding flat area of outer repair piece to weld to, as well as some vertical inner sill wall etc.....
Remember, mig or arc welding ( or any other type of welding for that matter ) is mostly all about prep, no paint, no rust, no filler, no seam sealer, no underseal etc.., no volcano !! Machine set up and practise is equally as important and always have a minder for fire watch !
