Repair BROKEN Cast Iron Transmission Housing | Flame Spray Welding

Can we fix this broken cast iron transmission housing!? This housing is off a Caterpillar 140M Motor Grader which has been badly broken with a big hole in the casting and our customer can’t get their hands on a new transmission housing for months! Repairing cast iron is always a challenge so we will be using our preferred method of metal powder and jet flame spray gun with oxy acetylene to repair the broken housing. Will this method of flame spray welding work or fail?
In this video we are using:
- UTP Variobond flame spray gun
- Metalmaster HPM-150T Hydraulic Press

With that professional job, if i were the contractor, i would just put that new part on the shelf, and not bother swapping out this "defective" one. What a masterful piece of work, it will probably last the lifetime of the machine to be honest. Unless someone else does something dumb, like dropping it :)

If it was cracking and leaking, fine, have at it, but if it was now covered in dry mud and difficult to find, why bother? Kurtis is way, way good enough.

@@CuttingEdgeEngineering Yes, never seen that use before. Have done the bronze plate though, to fix up bores that were somewhat less than good, to get them to the point the shafting that ran in them, or at least the new shoulder bolts I used, would be a tight fit. Holes wallowed out, and the original pins were under 5mm diameter at the wear points. No way to get spare parts, seeing as the manufacturer, still in business, no longer supports a machine they made in the 1970's, and have less than a clue, though the parts likely are still on some of the modern versions, seeing as they likely use a similar version of the linkage. But the braze and drill was both faster and cheaper, and the shoulder bolt was $3, off the shelf. Now to get some flexible pneumatic cylinder shaft couplers for it.

Don't bother welding cast iron. Only lucky, or experienced people can pull it off, even when perfect tools are involved, and since this method ain't for everyone, learn to braze. Braze and cast iron go together like beer and pretzels. In this instance, for example, brazing a T profile plug, would make the whole area stronger than original (also, same principles apply, you can put a dissimilar metal there, as long as braze can stick to it). Back in the day, when brazing was part of the bread and butter, they used to braze steel strips over cast iron housings (think banding on a barrel) to make them stronger. I've seen housings from old, old Cats break crushers with this mod at the junk yard.

Great video. I've been welding for around 50 years off and on. This is the first time I have seen the puddle gun technique being used. That's quite impressive . I worked for a company that used a flame aluminumizing technique, but that was being used as a protective finish and not a structural repair. I would like to see more of this technique being used. Again , great video.

I'm a welder/fabricator with experience in this kind of repair. I can tell you this is one of the hardest repairs to perform, depending on the material. Grey cast iron is a nightmare, ductile is a little more forgiving, and mailable is almost as easy as steel. It depends on the carbon and silicone content, the distribution of the carbon and the grain structure. I usually use nickel/iron DC TIG or Alum Bronze AC TIG. But to weld steel in to cast iron is very hard, they have completely different coefficients of linear expansion. Steel, when heated, will always contract more than it expands. Cast iron hardly moves at all when heated, so the end result is, if it doesn't crack again while cooling, then stresses are set up that cannot be relieved by post heating, meaning that when the casting goes in to service there is a strong likelihood of it cracking due to operational stresses from vibration etc. The only way I have had any success is by peening the welds after every weld pass.

Hi Darren Garden, Just curious, I have a backhoe. Circa 1989. Back digger section held on by top and bottom pins. The bottom pin section holding the pin snapped through on both sides and made a very loud crack sound. Brocken area is like rough sand and a grey colour. Its some type of cast moulding. Its one massive section that the backhoe arm swings from. I did a spark test, sparks are relatively small and stay closer to grinder and are a red type of colour. It ships off like small bits of sand compared to mile steel where it peals off when using chisel. Any idea on how to fix this issue as its holding a massive amount of weight. The ram rod also snapped off when this happened. I had only just replaced the other ram rod which also snapped. Was thinking it is some type of cast iron? If so, would a Ni 55 or NiFe work? Also wanting to weld mild steel on outside to help support it. Was reading that Ni Fe can be cold welded. Any ideas greatly appreciated as this part can not be replaced.

@marinetrax Жыл бұрын

Oh forgot to mention, I only have a gasless mig and stick welder and propane torches. Also, would be impossible to heat up the part as its still on the machine and weights a massive amount. Part that broke off is 50mm high and 40mm thick. Broke off in two areas.

@darren-garden Жыл бұрын

@@marinetrax I used to make excavator lift arms and buckets. They are made from carbon steel and should be welded with er70s6 otherwise known as a18 mig wire or rods. Although mig is not recommended and dual shield flux core is recommended. Full penetration welds. Pre heat is essential or you will get weld embrittlement and it will crack. You also should post heat to stress relive, but not essential.

@marinetrax Жыл бұрын

@@darren-garden Thanks so much for your reply. Muchly appreciate it. Just to confirm, this is the section of the backhoe that the digger attaches to at back of machine. It has the breaks for the side shift and that holds the top and bottom pin. It is some kind of cast. I looked up to see what type of spark carbon steel produces and it says yellow. The sparks off this is more red and small. Not as small as cast iron, but the same colour as cast iron. And its brittle, peals off in sand like pieces and looks "sandy" grey. Do you still think that this is carbon steel? I was looking at using Ni 55 or NiFe welding rods and doing it cold weld as its impossible to heat up the whole piece as its a massive cast section. Thanks so much. I would post pictures for you but I cant on here. Thanks once again. Also, I don't have gas. I only have a gasless MiG or stick welder.

Well done !! I first used spray welding in the early 1980s, in the USA. You did an excellent job. I would only suggest 1 thing. In each of the corners I would recommend using a ¾ inch carbide burr for a radius. The same way drilling a hole at the end of a crack relieves stress, so does a radius. The metallurgy of the cast-iron housing was of a high-quality with a high nickel content. Lots of elasticity. 👍👍👍👍👍👍👍👍👍👍👍👍
