Fisher Body Corvair Unibody Assembly

In my 50+ years of Corvair Nut I cant recall seeing pictures of the unibody being welded.

Obviously there must have been multiple jigs and where were the Fisher plants located.

So how many plants were there...did they TIG, MIG, oxy/acetylene gas, or stick weld them.

I believe all welding was resistance welding.

Pretty sure Tom is correct.. They has some sophisticated robots back then, in addition to the crew.

Here is an older thread that has a video that Kevin Willson uploaded..

I've seen some photos, I'll do some additional research.

Hope Rick Loving chimes in.... thumbs up

The vast majority of all 1960-1969 Corvairs were built at the Chevrolet and Fisher Body assembly facilities in Willow Run. In the sixties, Corvairs were also built in California (Oakland & Van Nuys), Kansas City , Missouri and in Canada at Oshawa , Ontario . Willow Run was always considered to be the "home" plant.

Yes in the above thread at 16:25 ish he is resistance welding.

I snipped a screen shot at 16:12 right before the welding footage.

Not sure about other assy. plants but at Willow Run, Fisher Body was right beside the GM assy. plant. When Fisher Body completed their part it was sent through the "Hole in the Wall" To stay ahead, not sure if the finished bodies were "Banked" on the Fisher or the GM side.

Great topic! Come to think of it, in 54 years swimming around in this hobby, there has actually been very little discussion about the body assembly process.

Dave N had a series of articles in the Communique several years ago where he interviewed several people from Fisher.

Can't think of ever seeing a picture of a LM being welded together!

Resistance welded with a machine like this one?

Fisher had plants adjacent to EVERY Chevy, Olds, BOP, Cad etc. CAR assembly plant. Sometimes they were in separate buildings, connected by a conveyor; sometimes the buildings were physically attached, and sometimes they were under the same roof but divided by a wall, as in Van Nuys. In all cases, though, they were autonomous financially and in management from the car division (Chevrolet, Buick etc.) "side" of the plant, though they had to work together intimately. Each body delivered to the car division was bought from Fisher by the division, if accepted. Any repairs due to Fisher goofs were charged back to the Fisher side. There were also certain assembly operations that were done by Fisher for Chevy, and vice versa.

Fisher Body, like any assembly process built the bodies starting with individual stampings, assembled into sub grouped units, then eventually all assembled or added to the overall body to finish the car.

If you look in the GM Assembly manuals, you can see each "year" and body style with all the panels in an exploded view...these were all just welded together in a specific pattern to allow for final assembly.

Yes pretty much, just larger current available so you don't have to wait so long between welds.

There was a LOT more to what Fisher did than that! The bodies were all painted, polished, and ready for final assembly over the wall.

They were spot-welded together as others have said. I have never seen any other type of welding on a car body. They're still made the same way today, only a higher percentage of the welds are done by robots.

Most cars today have extensive laser welding in addition to the venerable spot weld.
