Final answer:
When designing a brazement, an increase in joint length should be paired with a corresponding increase in joint clearance, brazing temperature, and heating rate.
Step-by-step explanation:
When designing a brazement, an increase in joint length should be paired with an increase in joint clearance. This is because as the joint length increases, there needs to be enough space for the brazing material to flow and fill the joint properly. If the joint clearance is too small, the brazing material may not distribute evenly or may not fully penetrate the joint, resulting in a weak bond.
Additionally, an increase in joint length might require a higher brazing temperature and a slower heating rate. This is because a longer joint takes more time to heat up and the brazing material needs to reach its melting point evenly throughout the joint to ensure a proper bond.
The base metal thickness can also have an impact on the brazing process. Thicker base metal may require higher temperatures or longer heating times to achieve proper bonding.
