Investigation of the Fatigue Strength of the Welded Joints Treated by Tig Dressing
The fatigue fracture of structural details subjected to cyclic loads mostly occurs at a critical cross section with stress concentration. The welded joint is particularly dangerous location because of sinergetic harmful effects of stress concentration, tensile residual stresses, deffects, microstructural heterogeneity. Because of these reasons many methods for improving the fatigue resistance o...
متن کاملPrediction of the weld pool geometry of TIG arc welding by using fuzzy logic controller
The present paper describes fuzzy logic simulation of tungsten inert gas welding (TIG) process to predict the weldment macrostructure zones' shape profile characteristics. The prediction of the weld pool geometry together with the shape of the heat affected zone (HAZ) was accomplished taking into account of TIG welding process parameters such as arc traverse speed, welding current and arc lengt...
متن کاملFatigue damage in solder joints
Miniaturisation of electronic products is increasingly important for reasons of functionality enhancement and freedom of design. This is realised by integration into silicon and developing miniature packages with high I/O and power dissipation density. Generally this leads to elevated temperatures, not only in the components but also in the solder joints. Elevated temperature cycling leads to f...
متن کاملFatigue Life of Repaired Welded Tubular Joints
In this study, the effect of repair on fatigue life of tubular joints is investigated. Six cracked specimens precedently subjected to fatigue loading undergone to weld repair. Two of those specimens were shot peened before primary fatigue loading. It is shown that repair gives rise to about 150% increase in fatigue life for original specimens while the increase of fatigue life for shot-peened ...
متن کاملFatigue Life Prediction of Rivet Joints
Strength reduction in structures like an aircraft could be resulted as cyclic loads over a period of time and is an important factor for structural life prediction. Service loads are emphasized at the regions of stress concentration, mostly at the connection of components. The initial flaw prompting the service life was expected by using the Equivalent Initial Flaw Size (EIFS) which has been re...
