Welding body panels (MIG, rookie) questions
Posted: Sat Nov 28, 2020 11:36 pm
Good evening! Very glad to be here. Newish to welding and very new to autobody work (the right way)
I have an 86 Grand National, and I have its donor, an 84 Regal. I will be essentially swapping my complete driveline and every body panel to the 84 Regal chassis, seeing as its complete and will be easier for me than doing a shell swap (no easy access to a lift)
My questions -
I will be replacing the floor pan, filling in some rust holes around the front and rear windshield area, and installing a patch panel on the passenger rear quarter. I have a LOTOS 175A MIG running 220V, and will run two setups - 100% argon with Silicone Bronze wire, or 75A/25C with some mild steel wire (70S6 is what it's running now). What would be the best way to prevent warpage when working on that quarter? I'm assuming the floorpan should be pretty straight forward, and some warpage will not hurt. It's going to be 90% butt welding. Im thinking the SiBronze wire will be ideal on the rear quarter seeing as its melts much sooner than the steel, but butt welding with this wire is very tedious.
Please remember I am here for advice, and want to do this myself. I'm mechanically inclined and have welded quite a bit of stick, but not alot of MIG.
