What is the purpose of a brazing schedule?

A brazing schedule plays a crucial role in the brazing process by specifying temperatures and times for the process. This ensures that the joints are heated to the correct temperature to allow the filler metal to flow appropriately, achieving the desired bonding strength and integrity. By adhering to a precise schedule, operators can control the heating and cooling rates, thus minimizing the risk of thermal stresses or distortion in the materials being joined.

Having a defined schedule also helps in maintaining consistency across multiple brazing operations, ensuring that every joint is produced under the same conditions, which is essential for quality assurance. Additionally, the right temperatures and times are vital to achieving the proper capillary action required for filler metals to flow into the joint, as well as ensuring that the properties of both the base materials and the filler metal are maintained throughout the process.
