During which phase of the brazing process is inspection most crucial?

The pre-braze phase is critical for inspection because it involves preparing both the base materials and the joint area before the actual brazing process begins. During this phase, it's essential to ensure that the surfaces to be joined are clean, free of contaminants, and properly aligned. Any contaminants such as oil, dirt, or oxidation can interfere with the bonding process during brazing, potentially leading to weak joints or failure in functionality.

By conducting thorough inspections in the pre-braze phase, technicians can identify and rectify issues before they become problematic during or after the brazing process, ultimately enhancing the quality and integrity of the final joint. This proactive approach helps prevent defects that could compromise the performance and durability of the assembly.
