The process to braze steel or stainless steel parts in a continuous conveyor furnace using generated (Exo, DA etc) or synthetic controlled atmospheres (N2-H2-base) can be broken down into the following six(6) steps starting from the enterance of the furnace:
1. Complete removal of oily deposits on the parts left from some previous operations
2. Complete removal of chemical or hydrocarbon additives in filler metal paste (if used)
3. Parts surface oxide reduction--especially at the joints
4. Maintaining uniform temperature across the parts especially near the joint areas just before the melting of the filler metal
5. Uniform penetration of the molten filler metal into the joints to fully braze the parts
6. Controlled cooling to avoid distortion and discoloration of the brazed parts
This presentation will analyze each of the six(6) steps in detail. It will show that 20 to 40% increase in throughput is achievable by doing some "make over" to the existing furnace so that each of the six (6) steps is carried out MORE efficiently, effectively and uniformly.
Furnace atmosphere brazing process is broken down in six(6) steps. The presentation will analyze each of the six steps and show that more or less 33% increase in production rate is achievable by doing some "make over" to an existing brazing furnace.
