What Are The Types Of Brazing? “7 Brazing Types Explained” will be covered with nothing held back.
What are the types of brazing? In general, there are 7 main types of brazing.
They range from torch and furnace brazing to vacuum brazing and they all are subtly different which allows them their own brazing category.
Brazing is a fascinating technique used to join metal pieces together, and so far we have been speaking about brazing as one uniform term, but actually, there are many different types of Brazing.
In this article, we’ll take a closer look at all the different types of brazing. So, without further ado, let’s jump straight into the action.
What Are The Top 7 Types Of Brazing?
As we have seen in the introduction, there is a grand total of 7 different types of brazing that we make a distinction between. But what types of brazing are these exactly? Let’s take a look.
The 7 types of brazing that we will be looking at today are torch brazing, furnace brazing, silver brazing, braze welding, cast iron welding, vacuum brazing, and finally dip brazing.
We will look at the subtle differences between the types as well as the overall brazing process.
What Is Torch Brazing?
We now know what types of brazing we’ll be looking at, so let’s jump straight into the action with the first type on the list, torch brazing. What is torch brazing and how does it work? Let’s find out.
Torch brazing is a very basic and authentic type of brazing, where a torch is used as a heat source to melt the filler metal to form the brazing joint.
Torch brazing is great for precise applications as a torch is great to control and aim. This is what we generally talk about when we talk about brazing in general.

What Is Furnace Brazing?
With torch brazing out of the way, it is time to move straight through to the next type of brazing on the list, furnace brazing.
Let’s take a closer look at this technique and its advantages.
Furnace brazing is a technique where heating elements or gas furnaces are used as a heat source.
Furnace brazing does not require the use of flux and its main benefit has to do with heat control, as furnace brazing is great for precise control.
What Is Silver Brazing?
Let’s continue working our way down the list of different brazing types, next up we will be looking at silver brazing. What is silver brazing and how is it different from the other techniques?
Let’s take a closer look at silver brazing.
Silver brazing is similar to the other types of brazing, but with one main difference. That difference lies in the filler metal used, and you guessed it, with silver brazing that filler metal is silver.
This causes the joint to behave differently which can be useful in some situations.
What Is Braze Welding?
Following the previously mentioned list, the next type we’ll look at is braze welding. This one looks a little different than the traditional techniques discussed earlier. Let’s take a closer look.
While the word braze welding looks different from other techniques, it is actually incredibly similar to traditional brazing.
The only difference lies in how the filler metal is applied to the joint, braze welding applies heat in a much more concentrated way while regular brazing focuses on a larger surface.
What Is Cast Iron Welding?
We will now move on from one type to the other, with the next type of brazing that we will be discussing being Cast Iron Welding.
This sounds impressive, but we will cover everything you need to know about this technique.
Cast iron welding actually is quite different from the other techniques discussed in this article. Cast iron welding is a form of welding where lots of heat is used to melt the two base pieces.
There is no filler metal involved in this process.
What Is Vacuum Brazing
Let’s get back to regular brazing techniques for this next type that we will be looking at which is vacuum brazing.
This is an interesting technique, so let’s jump straight into the action by taking a closer look at vacuum brazing.
Vacuum brazing is exactly what you would expect it to be, brazing in a vacuum.
Doing this eliminates oxidation and forms stronger joints between the two metal pieces.
Vacuum brazing is often done with critical components in assemblies.
What Is Dip Brazing?
The seventh and therefore final type of brazing that we will be looking at today is a technique known as dip brazing.
But what is dip brazing and how does it differ from the other techniques mentioned today? Let’s find out.
Dip brazing is similar to the other types of brazing discussed today, the major difference is that dip brazing takes place in a large salt bath.
This prevents oxidation and strengthens the joint, essentially acting as some form of flux.
Final Thoughts On… What Are The Types Of Brazing? “7 Brazing Types Explained”
All in all, brazing comes in many different ways. Today we have discussed the top 7 types of brazing that are used most often.
No matter what method you use, you will be guaranteed to have incredible results if you apply the method correctly.
We hope that this article has been useful to you. Thank you for reading and good luck on your brazing journey!

Frequently Asked Questions
Let’s finish off by looking at some frequently asked questions on the topic.
What type of brazing is best?
That depends on what you’re looking for, every type has its own application.
What type of brazing is easiest?
Traditional torch or furnace brazing is probably easiest for hobbyists as there is lots of information to find online.
What type of brazing is cheapest?
Torch brazing is the cheapest technique as it doesn’t require expensive equipment to get started.
What type of brazing is strongest?
While not technically a form of brazing, cast iron welding is the strongest technique mentioned on today’s list.
What type of brazing is safest?
All techniques mentioned require high temperatures and are therefore considered dangerous. The safest would probably be furnace brazing as the heat is divided equally and safely.
