Frequently Asked Questions for Induction Heating— Part Three

There are a various kind of different questions and puzzles about induction heating when it’s your first time in getting in touch with this technology, it may be a complicated or sophisticated question about the working principle of induction heating, or it may be a simple or brief question about the operation — how to use an induction heating machine. Well, all that you have already known or want to know will be clearly introduced in this article.


How do I select a braze alloy?

We have already put together a Brazing Alloy Selection Guide to help you choose the best option. It depends on the composition of your part, how and where it will be used, and the required joint strength. There is another helpful service that we provide for our customers is to put them in touch with an experienced braze alloy supplier.
We’ve been running these old vacuum furnaces for years. How can we set up a leaner operation?
The best thing you can do now is unplug those old furnaces and invest in a quick, clean vacuum induction system. Our new compact induction furnace will fit right into your manufacturing cell.


How hot does the induction coil get?

The induction coil is cool to the touch; the heat that builds up in the coil is constantly cooled with circulating water.



Can you use induction heating to braze steel parts in a nitrogen atmosphere?

Yes you can, but the nitrogen has to be clean and have a low dew point.


Can diamond bits be brazed with induction heating?

Sure, in fact induction heating is the most preferable method for diamonds bits because it works so quickly. The longer the diamond remains at heating temperature, the faster it degrades. We recommend atmospheric brazing in a vacuum atmosphere for the best results.


When is it better to use the indirect heat of an induction furnace instead of direct induction heat?

Yeah, we get that question a lot. It depends on the geometry of your part and how you want to heat it. If you have a part with simple geometry and your process calls for heating a specific area of the part, direct induction heating will generally be preferable. However, if you need to heat the entire part, or if the part has a complex shape, then you’ll achieve better results with an induction heating vacuum furnace.


Can induction be used to nickel braze in nitrogen?

Yes, with a vacuum system. We’ve had some success in with foil preforms, but we’ve had no luck with nickel paste because the binder in the paste doesn’t flow. So we suggest using a high vacuum system because it will work faster than oven heating and there is no time for nitrides to form.
