What is a brazing furnace? 5 Key Points Explained

A brazing furnace is a specialized piece of equipment used in the manufacturing process to join metal components.

It does this by heating them to a specific temperature.

This allows a filler metal with a lower melting point to flow and create a strong bond.

This process is particularly effective for joining metals that are dissimilar or for creating complex assemblies.

5 Key Points Explained

What is a brazing furnace? 5 Key Points Explained

1. Process Overview

Brazing furnaces were first commercialized in the early 1920s.

The process involves heating metal components to a specific brazing temperature.

This temperature is just above the melting point of the filler metal.

The filler metal, which has a lower melting point than the base metals, is then allowed to flow into the joint by capillary action.

Once the filler metal solidifies, it creates a strong, corrosion-resistant bond between the base metals.

2. Atmosphere Control

One of the critical aspects of furnace brazing is the control of the atmosphere within the furnace.

The right atmosphere is crucial for facilitating a strong brazed joint and ensuring better surface quality.

In some cases, such as vacuum furnace brazing, the environment is completely free of gases that could cause oxidation.

This is essential for preventing the formation of oxides that could hinder the brazing process.

3. Types of Furnaces

There are various types of furnaces used for brazing, including batch and continuous furnaces.

Batch furnaces, such as retort type furnaces for hydrogen brazing and vacuum chambers for vacuum brazing, are used for smaller, more controlled operations.

Continuous furnaces are used for larger-scale production and can handle a continuous flow of components through the brazing process.

4. Benefits and Applications

The benefits of furnace brazing include the ability to join dissimilar metals, create complex assemblies, and produce strong, durable, and leak-tight joints.

This process is widely used in various industries, including aerospace, automotive, and electronics, due to its versatility and the high-quality joints it produces.

5. Post-Braze Process

After the brazing process, the components are cooled or "quenched" to achieve the desired material properties in the finished assembly.

This cooling process can be controlled and is often carried out in separate areas or chambers of the brazing furnace.
