What might happen if the thin part of a joint is heated excessively while brazing?

When the thin part of a joint is heated excessively during the brazing process, it is likely to warp or collapse due to the intense heat. Thinner materials have a lower thermal mass, which means they can reach higher temperatures more quickly and are more susceptible to changes in shape under thermal stress. This excessive heating can cause the metal to lose structural integrity, leading to deformation such as warping.

In brazing, controlling the heat is crucial, as it is important to ensure that the filler metal flows into the joint without compromising the base materials. If the thin areas of the joint become too hot, they may lose rigidity and fail to support the integrity of the overall assembly. This can result in an improper bond or even a complete failure of the joint, which is why precise temperature management is essential in the brazing process.
