Can anyone help me figure out if its possible to replace this piece? (8 Viewers)

Flux core will be ok if you just make tack welds on top of each other and let cool every so often. If you can reach the back of the panel put some copper or aluminum bar backing the weld to absorb heat. I seen my old roommate replace his quarter panel on a 68 Camaro and ran a almost continuous bead with flux core and the whole welded area of the panel sunk in and looked like the inside of a boat hull.

For a part that is less visible, I wouldn't rush out and spend a pile of cash on a gas welder. But you'll get much better results if you do.

Another thing I like to do is keep an air hose with a nozzle handy. You will catch stuff on fire (undercoating, for example), and it allows you to cool welds.

I am not an expert welder, but I have had some luck with doing this kind of replacement with tack welds, spread out, moving to different areas, eventually filling all gaps.

also this will be my first time welding as well! and will be done with flux core...

If you get the gas attachment and add gas to your flux core machine, it will go better.
Also get the thinnest flux core wire you can find. I think they come with 0.035" wire and I think the thinner wire is 0.023" (from HF).

Lots of spot welds moved around to keep it cool. A continuous weld will shrink and cause it to have a huge "groove" where you welded due to the heat.

i got that titanium welder from harbor freight so it does both gas and gasless, so if im having a bad time or hard time ill switch over to gas. but i appreciate your advice thank you!
