Re: What was it like to work on the auto assembly line
I certainly won't argue with that. Then again, I've never looked at a Deere machine of any size to see just how nice and strong one of those 440"/minute welds looks. I'm trying really hard to understand the significance or logic (other than savin'-a-buck) of a human welding ANYTHING at such speed, yet expecting the best penetration and quality of welds for the end user. Did Deere X-ray or otherwise test these type of welds? Do Deere welders (YOU) hold any kind of certs? DD

So what "revisionist" books are you referring? The historians I know personally, and the others I don't know, base their work on good scholarship, deep-digging research and verifiable facts. We historians write what we can, but there is absolutely no way you can write about every single person's contribution in the Second World War. Judging by the amount of WWII books on the market these days, it seems we are doing our level best to tell as many stories as we can. Not every story is great and not every story is suitable to be published and marketed. We historians have been reporting on the greatest generation for a good long time now. Maybe you need to read some more history books so you can be disabused of this false notion you have about historians and what they write about. |

wire on the frames and the wire feeder had high speed gears with the feed speed turned way up. I just moved my arm and hand at about the speed I remember moving and came up with 360"s per minute. So I would say doing it every day what you claim is true. The spool of wire also turned pretty fast. I wonder how many lbs of welding wire was deposited per hour?? G.M.

Re: What was it like to work on the auto assembly line
I can't speak for other plants but at the GM Electro-Motive Division plant if I remember correctly mig wire came in large fiber (55 gallon?) drums. The locomotive under frames and crankcase weldments consumed lots of wire.

Mostly survey courses are taught--the basic framework of world and national history. You just can't teach serious, detailed WWII courses in grade school or high school. There is just not enough time in the day to teach individual WWII battles from 1939 to 1945. I was educated in the 60s and 70s--we were taught the basics. If a student wanted to learn more about WWII history, then he/she has to do what I did--visit a library and read books. There is no other way. Students, then and now, need to learn the basics first. That way the individual stories of the veterans and homefront workers can be learned in context. When you are learning to fix cars, you learn the basics first. No one starts out working on Packards or V-16s. Same with history education. Basics are learned first. Then it is up to the student to pursue the avenues of history that are the most attractive to that student. I agree that today's students--and many of yesterday's students-- are woefully ignorant of basic history. It is appalling. But the schools teach the basic frame work of world and national history. It is up to the student to pursue the details. And many -then and now- just don't give a care. Can't fix stupid. Can't blame the schools. It starts at home. |

I think the problem with the welding speed discussion here is that you guys are talking apples vs oranges - ole39 and G.M. (I think) are talking about the Wire-Feed Speed in inches per minute (i.p.m.) while CC is talking about the Travel (or work/welding) speed, which can vary significantly depending on the wire diameter, type of weld, etc... e.g. using 0.045 wire at a Wire Feed Speed of 400 i.p.m. might only result in a Travel (actual weld) Speed of maybe 15 i.p.m. for example. Clear as mud? |

Re: What was it like to work on the auto assembly line
randy, actually that does make sense. just never heard it put that way. many times we were told we're not welders, just "iron pourers". i ran a 2 man job and ran at 440 i.p.m. my partner ran at 700 i.p.m, (gasp!) we got done at the same time! my personnel preference is stick, its slow, smokey and dirty, but love it!

speed with .035 wire as you can with .045 IF you can get enough wire feed speed with the 035. The speed of the wire or wire diameter controls how many amps you get. I also stick with welding speed on frames to be 400 inches of weld per minute or greater depending on operator experience and configuration of the weld joint. G.M.

Re: What was it like to work on the auto assembly line
I have ground down the welds on Ford wish bones on several occasions and it is really interesting! The one I have worked with have almost NO penetration, the welds are just laying on the surface. As you start to grid them down the seams will pop apart. Very eye opening. They are apparently good enough for normal use as I have never heard of a failure, but cleaning the welds up with a grinder is not a good plan unless you intend to re-weld the seams (which is what I have gone). You have to wonder how good some of these speed welds are? Good enough I guess, but not what I would consider a proper weld.
