What is the last step to be completed in silver brazing preparation?

In silver brazing preparation, the last step to be completed before the actual brazing process begins is to support the components. Properly supporting the parts ensures they are stable during the heating process and helps prevent movement, which could misalign the joint. This stability is crucial as the temperatures involved can cause components to shift or sag, potentially compromising the quality of the brazed joint.

The process typically unfolds in a logical sequence; cleaning surfaces and applying flux are earlier steps that prepare the metals for a strong bond. Cleaning with acetone removes contaminants, while flux helps prevent oxidation during heating. Lighting the torch is an action associated directly with the brazing process itself, rather than a preparatory step. Therefore, establishing a proper support structure before initiating the torch is essential to achieve successful results in brazing.
