Abstract: In this article, multiple lumped thermomechanical characteristics of the welding process are regulated by modulation of the welding conditions in real time through feedback control. The controller ...

Abstract: This article provides a thermal analysis of scan welding, as a redesign of classical joining methods, employing computer technology to ensure the composite morphologic, material and mechanical ...

Abstract: A variety of geometric, material structure, and stress/distortion attributes are needed to characterize the quality of thermally manufactured products. Because of in-process sensing difficulties and ...

Abstract: Optimization of the weld quality and productivity requires in-process identification and simultaneous regulation of several thermal characteristics of the joint. Since in traditional single-torch ...

Abstract: A general thermal modeling and control methodology for thermal processing of layered materials for rapid prototyping technologies is established in this article. An analytical multivariable model ...

Abstract: In thermal manufacturing processes performed by a localized, sequentially moving heat source, simultaneous regulation of multiple thermal quality characteristics requires real-time control of the ...

Abstract: Complete solution of the welding control problem involves regulating weld geometry, residual stresses, distortion and weldment metallurgical characteristics. The latter has been largely ignored in ...

Abstract: The control of welding processes has received much attention in the past decade, with most attention placed on real-time tracking of weld seams. The actual process control has been investigated ...

Abstract: Scan orbital welding of cylindrical vessel, flange, and piping parts is performed by their rapid revolution under a radially or axially translated heat source, with its power modulated so as ...

Abstract: This paper presents a simple analytical model of the temperature and concentration dynamic distributions during thermal processing of intermetallic and metal-matrix composite coatings, such as ...
