I am not an expert welder, but my dad has welded all his life. He never heard of brazing cast iron. His recommendations are these: 1) Grind a "V" along the crack
2) Use a small nickel rod
3) Weld on low amp AC
4) "Stitch Weld", weld a small area ( around an inch ) across the crack ( at a 90 degree to the crack ), then peen the weld with your chipping hammer while it is still hot to relieve the stress. Let the area cool, then move about an inch further down the crack and repeat. The object is to keep the area as cool as possible.
5) This will take a while, but it will give you the greatest strength.

Cast iron is very sensitive, you do not want to get it too hot, and when it is hot do not cool it too fast ( do not pour water on it! ) or you will have cracking.

My grandfather had a 44 special that was in an accident shortly after he got the tractor. The tractor & a baler & a wagon rolled down a large hill hit a large tree head on. The tractor was in pieces. My dad welded all the pieces back together. The front casting ( where the engine & clutch sit ) was broke in two places. He welded them back together and we never had any problems with the frame breaking or cracking again. This was over 30 years ago.

Just had a tractor owner today mention to me about his transmission case that I repaired some 20 years ago. One of the supports in the transmission case had seperated from the main case. The support had been arc welded a couple of times. The owner of the tractor owned a large road construction company. Some 20 years ago I was in his shop working on a D9H Cat dozer that had threw a connecting rod. I was there to repair the hole that the rod had made in the side of the engine block. When I had finished repairing the damaged D9 engine block using brass, I was ask if I would be interested in repairing the transimmission case on the farm tractor. He told me today that the farm tractor had been used about 5,000 hours since I brazed the transmmission, the D9 engine had been used about 25,000 hours since the block had been brazed. He ask me how many repairs had I made over the years using brass. My answer would be in the hundreds. It is the only way that I knew. The method has been around for years, it was discovered before arc welding.

I did some research on this site & found lots of great information. Cast can be repaired with brass and it can br repaired with arc welding. Depending upon the situation one may be preferred over the other. If you were trying to repair a casting with a gasket or seal intact nearby, you would probably want to arc weld it because you could weld it at a low temp and not damage the gasket or seal. As I said before, this is a slow process, but a lot of cast repairs are done this way. Arc welds that fail are probably not welded correctly to begin with. Everyone seems to have their own thoughts on arc welding or brazing cast. I guess it just depends on the type of repair and the expertise of the welder.

I would weld the crack with a oxy-act torch using flux coated brass. Worked several years for Cat as a welder. Arc welding, (stick method), will cause future failures because the weld will but extra stress on the cast iron. Also the weld will crack where the arc welding burns into the cast iron. Cast iron has a open grain, and brass flows very well into the open grain. Arc welding cast iron is very similar to placing a support around or over the cracked area, a mechanical bond. Very similar to a doctor placing a cast over a broken bone. Arc welding will place stress (extra load) on the cracked area and when the original load is placed on the cast iron, the failure occurs again. Brass will not place any stress, the repaired area will only have to suppport the original load. I have used brass for over 35 years on cast iron and have found the cracked or broken area to be stronger after repairs were made. I have not seen any of the products that came on the market over the years that would weld cast iron that supported heavy loads. To get the best results with brass, be sure to grind the cracked area into a V so the brass with have a clean area and the grain of the cast iron is exposed. With a good coat of paint the brazed area will not be noticed. Good Luck!!

Go over to the TOOL TALK section. There are a few guys there that have the cast iron welding thing down to a science. Make sure you ask about hints, tips, procedures, etc. in addition to the welding rod type. I think they use what is called ni-cad rod when stick welding cast iron but that's all I know.
