The 348 and 355 Challenge cars have even worse welds because they had dealerships install the cages and hardly any techs knew how to weld. I imagine they had to do it that way because those cars had titles, they were homologated as street cars, sent to the US, purchased, then turned into race cars. The 360 and forwards are built properly at the factory but don't have titles so they can never be registered for street use. Maybe the M4 is the same deal (converted halfassedly after the fact rather than built from the ground up)

Why would anyone mig weld a roll cage? Especially somewhere easy to access like that gusset plate wtf

The only acceptable places to use a MIG welder in the automotive world is for chassis fabrication involving sheet metal, and even that is debatable. Generally speaking the only people who use MIG over TIG in something like a cage is because they either didn't have a TIG machine at the time or they couldn't afford one.

some additional food for thought:

THIS SAME ROLL BAR (ITS NOT A CAGE) COSTS $6500 AS AN OEM BOLT-IN ACCESSORY

THIS IS A $134,000 CAR

THIS IS THE FIRST THING YOU SEE EVERY TIME YOU CLIMB INTO THE CAR

honestly it doesnt matter if it would pass testing, it has too many visual defects and is undercut. its not a good weld.

>>16031891

Somehow I feel like that isn't a BMW factory weld, car companies these days have these things called robits doing the welding and they rarely half-ass things

>>16031893

MIG is all that's used in car manufacturing, the only people using TIG are racing teams and garages building cars, people who aren't mass producing.

>>16032011
MIG works better in manufacturing because:
1. You don't need to keep grabbing new filler, wire is fed through a gun. And you can be supplied massive barrels of wire.
2. It's technically easier to get different positions because you can use both hands to support the thing versus TIG, which is ONE HAND GUN, OTHER HAND FILLER.

the vw golf has a better quality interior than the one series

and the golf is made in mexico

sad really

I think if most people in this thread saw a track only car in real life up close they would probably have an autism fit.

If I saw this I wouldn't care, but I've also seen cages before and know that mig'd gusset welds look bad. The gusset is much thinner than the tubing so the weld builds up and you can't alter it after you lay it. it's not meant to penetrate the main crossmember, it's basically like tacking it on.

desu I would probably take this out and do a whole new real cage anyway if I was doing track shit.

should they have made sure it was cleaner, yeah probably. but, it is just a 100k production car not a pagani. They aren't going to stop the line and cut the roll bar out just because a gusset weld looks "bad".

the welds on the gt3 rs roll bar dont look any better than this.

Consistency is key to both a strong weld and to a pretty weld. If you have a tall, wandering crown like that, it's a sign of a novice welder that's not familiar with his equipment. Even if that weld has full penetration (which isn't unlikely), it still has stress risers everywhere. It should have been ground flat before paint.

Maybe for a consumer product at Wal-Mart, but not a BMW Lifestyle Accessory©. Welds aren't supposed to be uneven, undercut, and wander. Regardless of whether it performs the required function (not that it's a certified cage), it doesn't meet the workmanship standards for the car's price.

The car is cheap. You seem to think this is some kind of concourse car.

There's no undercutting. None visible anyway, naturally as it's painted.
It's uneven and raised because it's just a bead. There is no penetration. It's like gluing it on.
Mig beads always look shit when they don't have a fillet to sit in.

>>16038541
>There's no undercutting. None visible anyway,
I was about to say the same thing, then I looked again and saw the left side of the bottom gusset. The entire bead is undercut. Looks like the gusset is formed improperly, too.

>>16038541
The car is a quarter of a million dollars, and it's not a rough and ready race car. Do you realize how anal supercar owners are about details like this? This shit is also important because this roll bar is welded in, and if you wanted to fully cage the car you'd have to cut it all out and start from scratch instead of adding door and a pillar bars to the existing. You may think 'well the owner is a millionaire anyways he can get a whole new cage' but that's a shitty cop out because BMW didn't just hire a proficient company to build these roll bars to some standard so owners could remove the powdercoat, weld in some additional bars, and have a proper cage that can be certified.

You can get a VIN assigned if you're willing to go through the red tape and a bit of creative paperwork.

Lol you say 4 years like youre a veteran or something. While I agree with most of what you said, you're making alot of assumptions about the regulations involved in welding roll cages. It all depends on the WPS and what is allowed in the circuits. For all you know they cant go higher than a certain voltage to avoid damaging the structural integrity of the mild steel thats actually supporting most of the weight.
