great video. My dad used to have a shop and did major overhauls. The ford 390 heads used to be a big problem with fractures. We try to tell people when they start their car in the morning ( usually 0 degrees or lower out side temp) let the car idle for 3 or 4 min to prevent thermal shock to the exhaust side of the head. this is where the cracks usually develop. We would put the head in a kiln made for ceramic and slowly raise the temp to a cherry red and then weld the head immediately after welding ,the head would go back into the kiln and we would slowly lower the temp to prevent warping. I hope people watching your video pay attention as this is an art in itself an those that think they know it all will find they did not know as much as they thought after watching your video. Hats off to you for sharing your video and demonstration of true craftsman skills.

I had a cast iron head crack on an old 1988 Dodge Truck. I literally looked like Uncle Bucks car with the steam coming out of the exhaust. I removed and took both heads to a machine shop that heated them up in an oven that he made from stacked bricks and torch to preheat the metal. He then welded heads and pressure tested to assure he fixed all the leaks. He then allowed the heads to slowly cool to room temperature. He then machined the heads and installed separate seat inserts. The machinist made a comment that he has never had a cast iron head crack again after welding it with his process. Here is a behind the scenes look into what happened. Prior to unleaded gas, lead was use to protect the valve seats. After the switch to unleaded gas, the auto manufacturers had to start using hardened seats. There are two ways to get hardened valves seats. One was to machine the heads and install hardened valve seats into the head. The other way was to super heat the cast iron head and cooling it quickly by quenching it with water. This rapid cooling hardened the cast iron and was a cheap way to make hardened seats. The downside of this method is that the harder metal was more susceptible to cracking. That is why so many vehicles had heads cracking in the 80's. The machinist without knowing it was changing the cast iron back to the way it used to be and his separate valve seat inserts is the way that heavy duty heads are made. His fix wasn't a band-aid. It created something better than the original.

Welding cast iron can be troublesome for sure. Parts need to be clean as the driven snow, pre-heated & very slowly cooled. I've had good luck using 1/8" Nomacast rod, and cooling parts in sand or wrapping them heavily in welder's blankets. Looks like you 2 did a fine job! How cool is this "community" here? 500 & his parents just jumped right in... they (like a lot of the folks here) really are good people!

used to watch an old man in Bakersfield weld oilfield pumping unit engine heads that were cracked. he'd sit them on a wood burning stove and stoke the fire pretty good and let them sit there for an hour or 2 and then weld them and then stoke the fire again and go home and let them cool down gradually as the wood burned down and the stove cooled down to ambient temp. he'd always peen the weld Peening is one way to counteract the shrinkage forces of a weld bead as it cools. Essentially, peening the bead stretches it and makes it thinner, thus relieving (by plastic deformation) the stresses induced by contraction as the metal cools.

@michaeldvorak55565 жыл бұрын
I've seen it before were someone used a gas grill to pre-heat the cast iron. Size of part may not allow this. But after welding then they put in sand and completely covered with more sand to slow the cooling. Any part that isn't covered will cool at a faster rate and cracking likely.
@happykat3912 жыл бұрын
The Certanium rod is a necessity for large welding projects but Airco 375 is cheaper and works just as well for smaller items . Also, I learned that along with proper fixturing higher heat than you used is required if the part has to be re-machined through the weld line. I use an acetylene torch to bring the piece to a dull cherry red in a dim room before starting to weld. Then you can machine the piece with conventional tooling without running into hard spots at the weld/iron interface.

Hitting it with the point of your welding hammer throughout the weld process will relieve the stress in the weld and it's less apt to give you those hairline cracks as it cools. Keep up the good work !

I know I am a bit late to the party, but, I have welded cast many times with good results using Castaloy rods. Most welding supply chains have them, and they are not real expensive. Any high nickel alloy rod will do in a pinch. The prep and pre-heating is the key, which you obviously have down pat.

The reason the whole chunk came off is your heating it in one place. Cast iron can't be heated in one spot, if you really want to know how to weld it, you must place the whole head into a bed of red hot coals (wood stove) when it turns red be ready to go and weld it hot, then it will weld like steel. (try it :)
