I've seen some cast welds done by grinding a little chamfer on both sides of the repair also. Check out this link if you get a chance Dann.

The weld joint needs to be compleatly ground out so you get full penatration an filled back with a nickle rod I have used monel 60 rod with good results. TIG is the only way to go.
You know I welded cast iron ornamental railing banisters to steel square stock one time and it worked out really fine.
I learned a lot here so thanks for the info about brazing the inside cracks first.
Really good link on the fusion welding of those pieces, amazing cast iron repairs like I wish I could do! I was unable to get the grate to "black hot", just before red hot, and keep it there.
Carl, great description of how cast iron expands in 3d, and the temp differences as you go about trying to braze. Oxy/acetylene flame is 5700f so no wonder my brazes cracked going from one to the other across the grate.
I hope this will get me through the season with these botched dollops of brass I tried to get to stick to the thing
