All sounds good might even pre heat the " floor dry" or sand in very hot oven or forge.Unlikely that it will hold but here is what you do to try
First grind edges down "wide taper for welding in valley"
Prepare a bucket of plenty of size, 1/3-1/2 full of floor dry
Get a good pair of welding gloves and proper welding attire
Heat both halves with torch till orange, weld hot, and quickly submerge in the floor dry and finish filling bucket with floor dry
It will take at least 12 hrs to cool, the slow cooling is a key factor in this process, I use a wire feed, my brother uses nickel rod? Maybe? Can't remember for sure, he is the welder by trade in the family
Cast steel welds like steel.
If cast iron, pre-heat in oven, weld with Ni-rod, peen the piss out of the weld to relieve stress (the cast iron's, not yours), place back in oven & let cool down slowly.
If it is a break in cast Iron, throw it away and buy a new/secondhand part.Have a broken row unit on a jd 1860.ots about 1 1/4 inches thick and a clean break ,can this be successfully welded.i can do it myself or have a welding shop do it if it's very specialized. What are my options. Thanks
Hello 361turboi have an old stocktank half full of sand for welding cast. I use an old forge that i put a propane burner in and take my time in it seems to work well. I dont do realy important things. They go to a machinest in town and hes realy good! Ive broke hubs on my pull tractor and he welded those up for me. So a good weld job on cast will hold up.
