Has any one ever welded the C4 Corvette front frame rail impact bar. I had a small fender bender and the spot welds broke free. The frame is straight and there is not twisting, cracks or creases. The impact bar is the front cross member that holds the hood and nose. The problem is I don't have a spot welder. Can the frames flange edges be welded on to the impact bar in place of the spot welds? Thanks.
antfarmer2 wonder why they just spot weld the cross member instead of fully welding the edges of the flanges. seems that would be better than than the spot welds. any way, i'm going to have to hire a professional welder to do the job.
Front Cross member that holds the hood and front bumper, the spot welds separated.

The robotic welders are responsible.
You should see a body shop in action spot weld just about everything. Welding will draw and warp the metal much harder to control in mass production.
I painted cars in my youth. From what I remember from my ICAR course (which was a long time ago) it is generally acceptable to weld any kind of mild steel, however you choose to do it. You would best do this with a mig.
Welding is not, or may not be acceptable, on specialized steels. (Such as those found in door crash bars, etc.)
Because if you heat those up they lose strength and are effectively mild steel that won't do the job when called upon.
And again, assuming mild steel, it is acceptable to drill out a resistance type spot weld and replace it with a plug weld. This is a common practice in body shops, actually.
