Re: Replicating Factory Spot Weld Appearance
In the old days, the welders were set at one heat. As the tips got beat down the diameter increased. Guys would go at the tips and rough down the diameter. NOt exactly round now. Now they have steppers that step up the current after every so many hits so they still get a good weld even though the diameter has increased. Saves on hydro too. I can see how the out of round welds occurred. I repaired weld guns in the Oshawa "A" body plant from 1976 to 1983.
