I am looking to weld the axle tubes on a Ford 8.8 to the center pumpkin. The axle is being used on a Jeep I am building for semi-serious offroading. Anyhow, the center diff is cast steel, tubes are steel.
I am looking at putting 3 beads around each tube so that 1/2 of the circumference is welded (I figure that is enough and a complete bead is not necessary).
Anything special needed to weld to the cast steel?
Can it be done with my PM215, mild steel wire, and 75/25?
I have read on an offroading forum that low-nickel stick is the way to go, but isn't that for welding to cast iron?
