Welded differentials.....who is willing to admit that they have done it?

I used to weld the spiders in the dirt track cars we raced in street stock, they'd last the entire season with no issue. It was crude....but effective!!!

Some advice if you're going to do this....

Spray the spiders down with brake-clean or something similar first to get as much of the oil out of there as you possibly can. Make the first welds with a 6010 or 6011 rod....just enough to get a good base weld in that ties the gears together. Then switch to a 7018 low-hydrogen rod and go to town building up and fusing together all that you can. If you start getting porosity in the weld, stop and switch back to the 6010/6011 rod and burn the porosity out, then back to the 7018 to finish.
