Replicating Factory Spot Weld Appearance

[Keith Tedford]

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.
