In a joint that requires both heavy and thin sections, what should be monitored to prevent damage?

In a joint that involves both heavy and thin sections, it is crucial to monitor the thin part to prevent damage. Thin sections are more susceptible to overheating because they have less mass to absorb the heat effectively. When excessive heat is applied, the thin part can warp, melt, or become adversely affected, compromising the joint's integrity and potentially leading to failure.

While it is important to consider the heavy section as well, it generally can tolerate higher temperatures due to its greater mass, which acts as a heat sink. Therefore, careful temperature management focused on the thin section is essential during the brazing process to ensure a strong, durable joint without damaging the materials involved.
