MODELING OF THE WELD PRIMARY MACROSTRUCTURE FORMATION AT LASER WELDING

Vestnik Gosudarstvennogo universiteta morskogo i rechnogo flota imeni admirala S. O. Makarova, 2022
In modern shipbuilding, those enterprises and shipyards that introduce innovative and highly efficient technologies gain an advantage in the competitive struggle. The experience of the largest European shipyards, such as Meyer Werft and Blohm und Voss in Germany, Kvaerner Massa Yard in Finland, Fincantieri in Italy, shows the great potential of laser ...

Dislocation model of the formation of a welded joint in cold welding

Materials Today: Proceedings, 2021
Abstract The dislocation model of welding joint formation during the process of cold welding is proposed. The relations were obtained and the estimated grade of tendency of a number of metals to cold welding was performed on the grounds of the hypothesis of active centers limiting sizes.

Weld defect formation in rail thermite welds

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2006
A previously developed heat transfer model is used to study the influence of welding parameters on weld defect development in thermite welds. Weld defect formation maps are constructed from a series of heat transfer simulations. For the current normal rail thermite welding conditions, it is found that shrinkage cavity formation can be avoided but cold ...

Weld formation control for arc welding robot

The International Journal of Advanced Manufacturing Technology, 2008
The control of weld formation in gas tungsten arc welding is required for “teach and playback” robot to suit the gap variation in the multi-pass welding process. This paper presents a robotic system based on the real-time vision measurement. A close-loop control system is developed for weld formation control in backing welding. A novel prediction model

Formation of Seam and Charge Welds in 2D Extrusion Welding

AIP Conference Proceedings, 2011
The conditions of extrusion welding when extruding through an empty or a filled die is investigated by experiment combined by FEA. An experimental grid pattern technique has been successfully applied to study metal flow in both cases. Finite element models have been created using Deform 2D and 3D.
