Wow, i thought mine was bad on the inner arches when i peeled back a previous "repair" (new arch badly tacked over the old rusty arch) this one is much worse. Top job guys.
I've just found the same problem on my 1995 mitsubishi! Some utter prat just slapped a panel over the front offside chassis floor/sill just behind the wheel arch. Not only is it the worst bit of welding I have ever seen in my life (drips, lumps of weld metal left inside the frame, all sorts lol) but they also welded the 3 drain holes in that area shut thus creating a sealed frame section that was never supposed to be sealed, then covered it all with rubberized crap to hide the bodge. 4 years ago when I was doing my first restoration it all still felt solid, and I did an exterior rust strip (using a wire brush and phosphoric acid) then a waxoyl underseal, not realizing the inner wheel arch skin was slowly rotting from the inside! Fast forward to now and there's four or five 3 inch rips in the wheel arch skin around the dodgy weld and what was the original floorpan skin has just turned to magnetic crumbs which I scraped out earlier... (Was originally a thumbnail sized hole which I was planning to sort out but during a recent suspension rebuild the full extent to the problem made itself known...) The saving grace is that the mainframes underneath are still 100% solid and the rot hasn't spread to them at all yet. Already got fluidfilm on order to scope in there and protect them. All I can say is.... My mechanic's mate is definitely gonna have some fun with his welder in a couple days haha! And I'm definitely paying the price for some idiot's bodge 5+ years ago before I even owned the car... But she's too rare to scrap, and I've put way too much work into her to give up now. Still, it's only a fraction (10% if that) of the damage shown in this video so that gives me hope! My engine is bulletproof (4g93 DOHC) and everything else is 100% mechanically sound (with spares on hand) so I think the old girl is gonna defy death one more time! :)
I see where you have little square holes that are cut out, but I don't see you replacing them. Maybe there're not necessary, but a simple way to make them is to get a broach that cuts square holes. You drill a hole to the required size, go to the press that I see you have, insert the broach into the hold and press. Voila! A square hole!
Not everything is worth showing a repair on :) we do repair them but we don’t show the repair as we have covered a repair like that before and unless it’s complicated viewers don’t want to see it again :)
If you watch our other videos we sometimes refer to the bits we don't always show. Like prepping the inner sides of panels etc Also this whole car will have cavity Waxoil in addition to that :) 👍
if you mean the tack welding that ends up being one long continuous weld, thats because a continuous seam weld would put to much heat in the metal and warp it or burn through :) 👍🏻
