Galaxy uses exothermic-atmosphere brazing for aerospace and defense components that benefit from a continuous furnace process. Parts move along a conveyor belt through controlled heating and cooling zones within a furnace, allowing for steady, efficient production of high volumes.
Exothermic-atmosphere brazing takes place in a continuous-belt furnace containing a controlled gas atmosphere. Before entering the furnace, components are prepared with the appropriate brazing alloy and fixtured as needed. They then travel through controlled heating and cooling zones on a continuous belt. Furnace temperature and belt speed are established so each assembly reaches brazing temperature long enough to form the required joint without unnecessary exposure to peak heat.
Because the furnace operates continuously, parts can be loaded and unloaded throughout a production run. This differs from batch furnaces, where an entire load must complete a thermal cycle before the next group of parts can be processed.
The process can be well suited to:
Exothermic-atmosphere brazing is well suited to compatible copper, copper-alloy, and non-chromium-bearing steel assemblies.
Because the suitability of exothermic-atmosphere brazing depends upon a complex set of factors, Galaxy provides customers with specialized technical support that begins long before parts enter the furnace. We review the materials, joint design, and required metallurgical properties before production begins, establishing the parameters of the braze around the needs of the assembly..
Our experienced team can help determine whether the process fits your materials, production volume, and performance requirements. Bring us into your design process early to benefit from our expertise.
