Brazed joints utilize a filler metal that aligns with the American Welding Society (AWS) standard AWS A5.8. This standard specifically addresses the classification of filler metals that are used for brazing, which is a process that connects materials through the use of a filler metal that has a melting point above 450 °C (more than that of the base metals). Brazing typically involves heating the base metals to a temperature that allows the filler metal to flow and bond with the surfaces, thus creating a joint that enjoys distinct mechanical and thermal properties.

The significance of AWS A5.8 lies in its focus on establishing the quality and characteristics of the brazing filler metals, which ensures that the joint produced will perform reliably under the specified conditions. Hence, this standard is crucial for ensuring the integrity and performance of brazed joints in various applications.
