Welding Procedures and Type IV Phenomena
In this work, we attempt a quantitative estimation of the type IV rupture stress for welds in ferritic power plant steels containing 9–12 wt. % chromium, using a neural network in a Bayesian framework. This article describes the methodology that was used in creating and evaluating the neural network model. The sensitivity of the rupture stress to the test conditions, the composition of the stee...
متن کاملModeling of transport phenomena in hybrid laser-MIG keyhole welding
Mathematical models and associated numerical techniques have been developed to investigate the complicated transport phenomena in spot hybrid laser-MIG keyhole welding. A continuum formulation is used to handle solid phase, liquid phase, and the mushy zone during the melting and solidification processes. The volume of fluid (VOF) method is employed to handle free surfaces, and the enthalpy meth...
متن کاملImaging of snapping phenomena.
Snapping phenomena result from the sudden impingement between anatomical and/or heterotopical structures with subsequent abrupt movement and noise. Snaps are variously perceived by patients, from mild discomfort to significant pain requiring surgical management. Identifying the precise cause of snaps may be challenging when no abnormality is encountered on routinely performed static examination...
متن کاملTransport Phenomena and Keyhole Dynamics during Pulsed Laser Welding
Numerical and experimental studies were conducted to investigate the heat transfer, fluid flow, and keyhole dynamics during a pulsed keyhole laser welding. A comprehensive mathematical model has been developed. In the model, the continuum formulation was used to handle solid phase, liquid phase, and mushy zone during melting and solidification processes. The volume-of-fluid method was employed ...
متن کاملAnalysis of Welding Shrinkage
The problems of distortion, residual stresses and reduced strength of structure in and around a welded joint are of major concern in the shipbuilding industry and in other similar manufacturing industries. The present paper deals with the theoretical analysis of transverse shrinkage in a welded butt joint. The mathematical model used in this analysis is based on the assumption that the plate un...
