A welding question

Well-known Member
I have a front axle from a 52 Ford 3/4 ton truck that I am modifying to use under a wood wagon I am building. It is very heavy. It will be the front axle that steers. I am welding different spindles on it and need to shorten it a bit. Also will weld a center swivel pin holder so it can pivot up and down. It is a drop forged axle. Hardest metal I have ever tried to cut. Wears out sawzall blades and grinding wheels. What type rod should I use when welding on it?
My thoughts are 7018. Been welding for over 55 years and never found anything as hard as this.
Thanks, Richard
 
Back in the 70s and 80s we used to buy Weldalloy S2E high-tensile rod for exactly what you are doing. I did many with a cheap arc-welder. Fantastic rod. 120K tensile strength.

It looks like the equivalent now is "Blue Rod 990."

Weld dissimilar alloys!

For dissimilar alloy steels and highest tensile strength. For
tools, dies, coil springs, leaf, spring steels, carbon steels,
stainless steels, wear, impact, heat and corrosion resistant welds.

Tensile Strength/ Hardness: 120,000 PSI - 500 BH
Type of Current : AC - DC
Welding Process: ARC, MIG, TIG
 
I've welded the tongue parts to homemade ones with regular 7014. Pulled them out with 400 bushel of corn on in the mud up to the rear axles with multiple tractors hooked together and 4wd tractors which ever I had available at the time. Never broke the welds yet been there since about 1981.
It is on 900-20's
 
Thanks guys. I am going to the welding supply shop tomorrow and see what they got.
We are lucky to have a very good store in town.
