Mechanical Properties of Brazed Joints - AWS Brazing Handbook Chapter F-5 - Author's Presentation

The Brazing Handbook, Vol. 6 Fundamentals of Brazing: Mechanical Properties of Brazed Joints, a new chapter in the Brazing Handbook, was published in 2025. The mechanical performance and therefore the suitability for service of any brazed joint is determined by many factors including, the base and filler metal properties, brazing method and parameters, brazement design (geometry, joint thickness), and the presence of any brazing imperfections. These factors are interrelated by the braze manufacturing process through a complex relationship of physical, material, chemical, and thermal interactions. The considerable number of variations and interactions among these factors results in a great variability in the structure, composition, flaw population, residual stress state, and therefore the mechanical properties of brazed joints. This chapter aims to provide a framework for understanding the effect of these factors on the properties, including (static) strength, fatigue strength, toughness, and creep resistance, of components containing brazed joints.
