Sheetmetal so thin these days

I turned into a snow pile when leaving my driveway today (turned too sharp). Crunch crunch crunch…Put a nice dent in the lower rocker panel. I swear the metal these days is thinner than ever before. Its like the expectation that any impact will cause damage. 2024 Silverado Crew Cab
When we went to the K2 truck platform is when I noticed significantly thinner sheet metal but still "decent" - however the T1 was even thinner and we would sometimes make small dents in panels just hand carrying them to the line if not careful. Robot handling damage was always an issue as well.
 
I used to drive '80s Audis that had a horizontal "crash bar" in the door. Haven't seen that in a loooooong time
I thought every vehicle had crash bars from about 2000-2002 when side impact standards were increased? I have never worked on a car that did not have a crash bar in the door.

In the pickup box in my truck each wheel hump has a rear facing dimple on it (pointing out) that seems like robot damage or an aggressive pinch welder or something. Neat to have your perspective on this. Do you work Ft Wayne?
 
My 2016 Tacoma uses pretty thin sheet metal....I can see the hood flexing in the wind at highway speeds. Gotta be careful leaning against the bed sides to grab something out of it....it all moves.
 
I like to weld for a hobby so I often go to the local muffler and body shop to get scrap metal. Exhaust tubing is great fun to play with but auto body sheet metal has become so thin that it's nearly impossible to do anything with if using a MIG welder. My most recent junk fender was from a 2019 Toyota Corolla. It measured 0.021" thick. I also grabbed a Mazda hood which was thicker but not by much. I can weld the hood and have used hood sheet metal to repair mower deck erosion wear but the Toyota fender is going back to the recycle bin. It's good for nothing other than holding the paint in place.

For comparison, I cut all my spin-on oil filters apart and have used oil filter housing metal for scrap projects. Some oil filters have thicker sheet metal than car bodies.... and some don't.
Strange hobby

I have worked at the Baltimore plant, Bowling Green and Arlington where I retired in 2022. Also other plants including Ft.Wayne when I was in engineering. Your truck may actually have a normal condition because it is unlikely 2 robots would be creating the same defect on the same truck. Hard to say for sure as it may actually be normal.

They're probably done more gracefully now so they look integrated into the design. That 80s Audi probably had them slapped in there just for the American market.
 
The Silverdao body panels are a mix. The hood is aluminum, the tail gate is as well.
Swing panels to include doors - corners are steel …
Several grades of steel form a safe cocoon - but the trade off is high strength steel can sometimes rust easier …
Keep them clean and coated !!!

Baltimore…Astro/Safari line I assume. I live in DC area, I was sad to see that plant close. Between that and Bethlehem Steel, that place got hit hard.
 
Every component is engineered to save as much weight as possible. Every gram counts...more weight = less performance, less fuel economy.

Snow piles can also be hard as a rock. When I was in HS a friend totaled a Tercel driving into a snow pile.
Yeah that is so true. I see plenty of 'snow piles' that are like concrete and would certainly damage a car if hit, even a vintage one. You really have to be careful and not hit them is about the only solution. Arguably a large snow pile sunk the Titanic as well, and that ship had pretty thick skin (plates). ;)

We were hanging out in the mall parking lot at 16 years old and my friend (who was obviously an idiot) comes screaming through the parking lot in his salvage title Tercel thinking he was going to drive through this snow pile in a blaze of glory. Slams into it and immediately comes to a stop. Front end crumpled, steam, a puddle of coolant leaking under the car.

Funniest thing I've ever seen. I can still hear how terrible it sounded at WOT with the belts squealing and all before he hit it.
 
For me it was turning too sharp coming out of my driveway and crumpling the lower rocker on a snow/ice pile that was there from when opening the driveway up. Obviously out of my line of sight. The moral to the story, dont be stupid. But I swear, the stuff is thin.
 
Agreed. I repaired this first gen Taco but even with .023" on the lowest setting it was quite an ordeal. In some spots I was able to fit a brass backer block and that helped...some.

My Hobart 210MVP was on 220V. I'm honestly not sure if going to 110V reduces the bottom output because on 110V you don't even use the first 3 or 4 lower power settings. I'm sure the actual V output is spec'd somewhere.
Usually the only great option is moving faster. High settings and faster movement often work better than slower and lower. And it’s less total heat.

.023 is often counterproductive on thin stuff because it has high arc intensity with the fine wire. Often an .030 or 035 will have less burn though tendency.
