  • Cast Iron Tractor Part

    This tractor part came in today with a giant cut out where the crack used to be. The part houses the steering box plus is the tank for the radiator and it froze. The guy ground it all the way thru and was going to braze it then he changed his mind. Neverless it was a large gouge. I gave it a few test tacks with some machinable cast rod and it looked like it was going to be ok so i proceded to connect the dots. Then i ground it all out and put some longer beads on it grinding between the beads as i went. I sprayed some pentrating suff on it and didn't see any cracks...Bob

    DID you hear any "ticking" after the arc ended?

    I was working on a turbo exhaust case the other day and spotting it with 100 amps for maybe 1/2 to 1 second was cracking it further.

    Dug a hole in the ground, lit 5 lbs of charcoal, and blew it with my shop vac, set the casting in the middle of the heat for 25 mins until it glowed, and welded away without any cracking.

            Filler rod?

            Done some cast welding myself , unless I heated the piece all I would hear is snap crackle pop! What type of filler rod were you using?

              Preheating is not required but will make a softer weld according to the directions. But since i was not going to machine it i didn't worry about it. I have used this rod for about 10 years with no problems...Bob
