Can I weld my cam bolts?

Take a good look at post #19,pic 2
I spent almost 6 years as an alignment tech, and I have seen that with brand new Moog bolts.
The first time, it was a do-over for me. But it didn't take long to figure it out. I put an extra hardened washer on the head end to pull those flats about 1/8th inch further in and problem was solved. After that, I just automatically installed the washers.
