What should be checked during the pre-braze inspection?

During the pre-braze inspection, checking the cleanliness and alignment of components is crucial for a successful brazing process. Cleanliness ensures that all surfaces are free from contaminants like oil, dirt, rust, or oxidation, which can hinder the fusion of the filler metal to the base metals and potentially lead to weak joints. Proper alignment of the components is also essential, as misalignment can result in improper fit and joint integrity, which may compromise the strength of the braze.

Ensuring that components are clean and well-aligned helps to create an optimal environment for the heat and filler material to flow correctly during the brazing operation, leading to a stronger, more reliable joint. This step is part of good practice and is fundamental in achieving high-quality results in brazing tasks.
