Why is it important to support parts during the braze operation?

Supporting parts during the brazing operation is crucial because it prevents parts from separating or misaligning under the influence of heat. During the brazing process, materials expand when heated and can potentially shift, leading to gaps or misalignment of the joint if not adequately supported. Proper support helps maintain the integrity and alignment of the joint, ensuring that the brazing material can flow correctly into the joint space, resulting in a strong bond. This is especially important in achieving the desired mechanical properties and longevity of the assembly.

While aspects like access for operation or cleaning are relevant to the process, they do not directly address the critical function that part support serves during the actual brazing.
