Atmosphere Brazing Furnace

A High Temperature Atmosphere Brazing Furnace is designed for clean, reliable, and high-strength metal joining under a controlled protective atmosphere. It provides stable high-temperature performance, uniform heating, and precise atmosphere control to prevent oxidation and ensure bright, high-quality brazed joints.

This type of furnace can be configured in different structural forms depending on production needs, making it suitable for various industrial applications such as stainless steel components, copper and nickel alloys, heat exchangers, and complex assemblies.

With flexible design options and consistent brazing results, it is an ideal solution for manufacturers seeking efficient and repeatable thermal processing.

The Brazing Process and Techniques

Controlled Atmosphere Brazing is a highly disciplined, multi-stage procedure designed to deliver consistent, high-quality results. The workflow typically includes the following steps:

Cleaning and Degreasing: Components are thoroughly cleaned to remove oils, particulates, and other contaminants, ensuring strong adhesion and proper alloy flow during brazing.

Metallization: A proprietary thick-film coating—usually based on molybdenum/manganese or molybdenum/manganese/tungsten—is applied to ceramic surfaces. This layer enhances wetting behavior, supports uniform alloy distribution, and protects against oxidation.

Brazing: The prepared parts are heated inside a continuous furnace operating under a controlled atmosphere (commonly nitrogen). This environment allows the braze alloy to melt, flow, and fill the joints without the risk of oxidation.

Cooling: The assemblies are then cooled under carefully regulated conditions to solidify the joints and preserve mechanical strength and dimensional stability.
