First patch welded in

Managed to find some time to start welding in the patches i had cutout. I started with a small patch in the drivers side footwell, this is the process i will use to do the rest of the car.

Area to be welded cleaned first with wax and grease remover then paint removed with a 2" Coarse grade Roloc disc on an angle air die grinder to avoid any removal of steel

Patch positioned and held in place in this case with magnets

Ist Tacks

Tacks nearly complete, notice large gap on untacked edge - not good, patch cutting practise required!

Copper pipe heat sink placed behind gap to help avoid tacks blowing through

Tacking completed

Stitched welded in short sections, not pretty especially along the seam with the large gap, penetration not a problem with 20 gauge!

Welds ground down first with a solid grinding disc, then as i got closer to the panel changed to a flap disc to avoid grinding the parent steel 

And from the other side

Definitely not happy with the look of the welds, practise and more accurate cutting of patches should improve this - onward and upward!!
