What should be conducted on each breeze joint to ensure the alloy has flowed completely around the joint?

Conducting visual inspection on each brazed joint is essential to ensure that the alloy has flowed completely around the joint. This method allows the technician to closely examine the joint for any signs of defects or inconsistencies, such as gaps, uneven surfaces, or insufficient fill. By visually inspecting the joint, the technician can confirm that the brazing material has adequately penetrated and adhered to both components, which is critical for the joint's strength and integrity.

Choosing visual inspection is particularly useful because it is a straightforward and immediate method for assessing the quality of the joint without the need for complex equipment or procedures. Following visual inspection, technicians often look for uniformity in the joint area, ensuring the brazing has created a consistent and robust bond.

While other options like pressure tests, leak checks, and functional assessments can contribute valuable information about joint performance, they do not directly verify the complete flow of the alloy as effectively as a visual inspection does. These methods may detect issues that arise under operational conditions or assess overall system performance but might not reveal localized problems with the alloy's flow at the joint itself.
