Brazing a Carbide Tip to a Steel Bar- Induction Oven

This is an introduction video on how to braze a Pretinned Carbide Tooth to a Steel bar. Using our Purified Flux the brazing process can be easy to navigate.

thank you Mam the information

[@keithmiller130]

would like to see you braze carbide tip to stump grinder teeth with oxi and aco

[@AuMechanic]

And the temperature used is what ?

[@majdq8]

What if the part to be brazed is not pre-tinned. Is the procedure similar or is there a way to pre-tin?

[@CarbideProcessorsInc]

I would recommend ribbon braze alloy. We would paint a very light layer of flux on each side of the ribbon and put that between the steel and the carbide. Make sure the carbide surface accepts the braze alloy and that the steel is clean.

[@majdq8]

Thanks for the answer I will check it out on the website. How much does the pre-tinning add to the the carbide part? I have a carbide insert that I need to put inside a metal part and would like to know how much tolerance to keep between the 2 parts to allow for proper brazing? Do you think .1mm will work or will I need more space between the parts to allow for the brazing alloy?

what kind of silver brazing rod are you are you using ???? I want to order some off eBay. I need to braze carbide stump grinding tips to steel teeth.

[@ljubomajstorovic5558]

did you find silver brazing rod on the ebay

[@carbideprocessors6959]

We stock multiple sizes of wire and ribbon braze alloy. Please visit our website www.carbideprocessors.com

You can probably get good braze alloy off of eBay but you need to be careful.
There are an awful lot of different kinds of braze alloy and many of the sellers aren’t all that sure about what they are selling.
We buy our braze alloy directly from the manufacturer so that we get a certified product where the any trace materials are somewhere around one or 2 parts per billion.
There are maybe five common, high silver, braze alloys that can be used in this application. The most common seems to be a 50% silver cadmium free alloy. There is a 49% alloy with manganese and a 50% braze alloy with cadmium that are both stronger. There is a 40% silver braze alloy that is not as strong but that is a little cheaper. There is a 56% silver braze alloy with tin that is easiest to use but is probably the weakest.
You also need a special brazing flux. That is a brazing flux with BRAZING in capital letters and underlined.
The terms brazing and soldering are often confused. Brazing can be considered as high temperature soldering. The separation point is typically 880°F although other temperatures are used.
If you go into a welding supply store and ask for flux you will typically get a soldering flux because that is far and away the most common usage. This flux will burn up too fast and you will not get good braze joints.

Thanke you for you reply. I am watching you channel for few weeks and i have learned a lot from you presentation. Can you ship flux and brazing alloy to Croatia this is in EU i could pay you through paypall or bank transfer you can send this through regular post. You can contact me at [e-mail]. Thanke you.

Hi Ljubo, I just emailed you information!

[@CarbideProcessorsInc]

Pretty hard to argue with that. I'll get Jo a better camera.
it is slightly better than nothing. A great number of our contacts seem to have very little, if any idea of how to braze.

[@trantuan-df6ns]

I like order this paste. Please offer

[@atlefatle]

totally out of focus this is

[@ShortKingzz]

Thanks yoda

[@lorifilm]

She in focus was pretty well. Mmmm

bad quality and sound
