Re: Replicating Factory Spot Weld Appearance
By the time I got to the truck plant, they had the weld gun tip dressers that Shonyenko describes. They also got tip dressers mounted on pedestals in the stations with the robots. The robots could take the gun to the dresser and have the tips dressed when required. The manual operators were famous for doing one or two less welds that they were supposed to. Got the job done quicker. The welders for putting the inner and outer wheel house halves together had to rollers that the current was passed through at intervals as they rolled around the arc. Guys would open up the flow control valves to speed up the operation. The weld checkers were always after us to slow the rollers down to get the required number of spot welds. Judges still have a lot to learn.

Keith
Do you have any personal photos you can post of your plant during those years showing the assembly process?

Re: Replicating Factory Spot Weld Appearance
GM still doesn't want cameras in the plant. Besides, by 1976 there wasn't much other than the Laguna to look at. From '65-'76, I worked in the old north plant in the big die room where we built new dies and did die repair on the dies in production. One dirty tedious job and I missed out on seeing all the neat cars being built.

Re: Replicating Factory Spot Weld Appearance
The Black 69 RS/Z survivor also has grind marks on the a pillars where the roof was leaded in and runs in the door jambs as well as the lower rear valence...
My 68 GTO has runs in the door and trunk jambs... which I will dupplicate when I paint it...

Re: Replicating Factory Spot Weld Appearance
How do you reproduce that? Do you use a spray bottle?
