What is a furnace brazing? (5 Key Points Explained)

Furnace brazing is a semi-automated process used to join metal components, particularly those with dissimilar materials, by using a filler metal with a lower melting point than the components being joined.

This method allows for the creation of a repeatable metallurgical bond, making it suitable for mass production.

The process involves heating the components to a specific temperature until the filler metal melts and flows into the joint, followed by cooling to solidify the joint.

5 Key Points Explained

What is a furnace brazing? (5 Key Points Explained)

1. Heating Process

In furnace brazing, the entire assembly is heated in a controlled environment, typically within a specialized furnace.

The temperature is carefully regulated to match the melting point of the filler metal, ensuring it liquefies without affecting the structural integrity of the base materials.

This is crucial as the filler metal must flow into the joint through capillary action, which occurs when the gap between the parts is very small.

2. Filler Metal

The choice of filler metal is critical as it must have a lower melting point than the materials being joined.

This ensures that the base materials do not melt or lose their properties during the brazing process.

The filler metal, once melted, is drawn into the joint due to capillary action, creating a strong bond between the components.

3. Cooling and Quenching

After the filler metal has flowed into the joint and the desired temperature has been maintained, the assembly is cooled.

This cooling process, often referred to as quenching, is done in a controlled manner to ensure the filler metal solidifies properly and to achieve the desired material properties in the finished assembly.

Cooling may occur in separate areas or chambers of the furnace to optimize the process.

4. Advantages

Furnace brazing offers several advantages, including the ability to join dissimilar materials, precise control over tolerances, and minimal distortion of the finished piece.

This method is particularly effective for high-volume production, as it can handle multiple components simultaneously, making it a cost-effective solution for industries requiring large quantities of brazed parts.

5. Types of Furnace Brazing

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

Batch furnaces are used for smaller quantities or when the materials are highly reactive to oxygen, necessitating a vacuum or controlled atmosphere.

Continuous furnaces are more suitable for high-volume production, where parts are continuously fed through the furnace.
