Brazed Joint Shear Strength
The brazed joint shear strength is the mechanical resistance of a brazed seam against forces parallel to the joint surface. It depends on the gap width and overlap length.
Physicochemical Mechanism of Action
The shear strength of a soldered joint determines how strongly it resists forces acting parallel to the joint surface. This property depends on the chemical composition of the solder and the mechanical properties of the metal.
Metallurgical Relevance & Welding Risks
Low shear strength can lead to gap formation or cracking, especially under high mechanical loads. This can compromise joint reliability and lead to failures in service.
Workshop Practice & Instructions
To ensure high shear strength, it is important that the solder joint is properly formed. This includes adequate overlap length and correct gap width. Soldering time should be long enough to create a homogeneous joint, but not so long that the metal overflows or deforms.
