First attempt floor repair

[78SWB]

I went to replace my rubber floor mat in my K5 and found some rust that needs some attention. Going to order a patch panel from LMC and cut out what I need to replace. I’m looking for any tips you guys would have for doing the job as I’ve never done this before. What’s the best way to deal with spot welds?

Spot weld drill bit. Drill from the side you need to remove.

You can get cheap one from harbor freight. Or good ones from Eastwood.

cut a squared off minimum repair that you feel is needed based on sheetmetal thickness... aka the screwdriver stAb.. cutoff wheel, sawzall, teeth..... start cleaning existing metal... media blasting can't be beat.. anything less, will bite ya in the arse given enough time...... trim more as needed, reclean....

and yeah, a spotweld bit is ideal.. you can use a nice large reg bit, like 5/8, but you'll get into the support a bit.. but you can plugweld it later... you can also use various other methods of destruction, a 3" cutoff wheel nipped at it, followed by some strategic air hammering, etc..

from that pic, I'll bet you'll be into the side panel a bit...

you can do any combo of butt/flange patchwork.. butt is better, https://www.eastwood.com/intergrip-...CVXnmyJ0IcWO9EnNMAqcSUoOiYxKTgpxoCj9gQAvD_BwE but strategic flange work can be vastly easier and fine/stronger when done correctly..

Any updates, headed down the same road soon.

I have been told to try and avoid any hard angles and make them rounded. This is to help prevent heat build up in a corner. Even when spot/stitch welding, the corners will heat up and distort or blow through.
