Weld on carbide teeth

[Tractor Seabee]

I will add to what is already said!

Can you even buy the new carbide teeth? Are they an exact replacement or do you have to modify something? How many are there to do, you cannot select but need to all or none. From your picture it is apparent they are silver soldered. First you have get the old ones off and clean up the old brazing. At least you will not have to coat the steel first. What are your brazing skills? What equipment do you have? You will either have jig up something to hold the new ones in place or have a helper to hold then till they are cooled to set. How fast does the wheel turn? Balance is something to consider. Be prepared to pay for 50% silver brazing alloy. It sells by the ounce not the pound Silver brazing carbide is not normally a DYI project. I consider my self to be an expert with silver solder and I would not tackle this project. Too easy to get the teeth out of line and not notice it till you are done. You will be hard pressed to find a shop that does such work as it is normally a manufacturing process to make the wheels.

You would be surprised what that blade can cut and clean. Cuts roots, asphalt and concrete.

What is that blade used for cutting?



Mr. HE

The blade is for a Janick Trencher. Cuts ground, roots etc

Some of the blades are made to be able to replace the teeth and some are not. Before you buy anything , I would heat up one of the teeth and remove it to see if it has a snap type of tooth or a groove that holds it in place. If it does, this would be a doable project. If not, you should use the tooth money towards a new blade. As I stated before, I have a bunch of silver designed for this task at a fraction of retail price. Good luck.

That blade is almost certain to have soldered or brazed on carbide alloy teeth. The Janick video says they use "mining grade" carbide on the blades. There are dozens of suppliers of new carbide and soldering it in place is not hard. It will take some calling around and I'd guess new carbide will run $1-3 per tooth. I just used bing.com and searched for "Mining carbide blanks and inserts" and got a few dozen options of places to call and see if they have the right size. Hope this helps, let us know what you find.

I have used silicon bronze rod and TIG'ed them on to steel before. Well twice, when I made broches to take the seam out of the inside of box tubing and was out of silver.
