Advanced Controlled Atmosphere Brazing Technology
Controlled Atmosphere Brazing (CAB) is a flux-based aluminum brazing process that utilizes a non-corrosive flux in a nitrogen-controlled environment to form high-strength, oxide-free joints. The CAB process consists of several critical steps:
- Thermal Degreasing – Removing oils and contaminants for cleaner, defect-free brazing.
- Fluxing – Applying a non-corrosive flux to prevent oxidation and improve joint quality.
- Drying ovens– Eliminating moisture to prepare components for brazing.
- Brazing – Precisely heating assemblies in a controlled nitrogen atmosphere for uniform joint formation.
- Cooling – Controlled cooling to solidify brazed joints without stress or distortion.
This continuous, oxygen-free brazing environment eliminates the need for post-braze acid cleaning and minimizes flux waste and environmental hazards, making CAB furnaces an economical and eco-friendly alternative to traditional brazing processes.
