Influence of brazing process and gap size on the fatigue strength of shear and peel specimen

Abstract Brazing is a joining technique used in many industries for components that consist of individual parts. Many these are cyclically loaded during service. For this reason, reliable approaches to assess the service life must be developed. purpose, it necessary gain knowledge about factors influencing fatigue strength and damage behavior. In paper induction, vacuum- continuous furnace brazed shear peel specimen with different brazing gap widths analyzed. Therefore, specimens were characterized, measuring geometry surface condition radii, tested under load control using constant amplitudes. It found manufacturing process parameters have significant influence on mechanical properties material, profile fillet radii. These again an behavior strength. particular crack-like defects varying severity, which can extend deep into located highly stressed areas radii also that, regardless used, there tendency area width number size increase increasing size, negatively affect depending
