Interface phenomena in aluminium–magnesium magnetic pulse welding

Science and Technology of Welding and Joining, 2008
The morphology and structure of the weld interface in magnetic pulse welding of similar and dissimilar metals were investigated. The interface zone of dissimilar metal couples such as Al–Mg, was studied in comparison to Al–Al welds. It was found that intermetallic phases (IMP) of different compositions are created during welding of the Al–Mg couple by

Magnetic Pulse Welding and Design

2021
Advent of a polyvalent solid-state cold-welding process titled “Magnetic Pulse Welding (MPW)” has un-wrapped scope for reconnoitering uncommon metallurgical behaviors. For a researcher investigating MPW welding with a view to applying it for non-ferrous and dissimilar materials, the available literatures is to some extent, sporadic, and scanty.

Welding Interface in Magnetic Pulse Welded Joints

Materials Science Forum, 2010
Magnetic pulse welding was applied to the lap joining of similar (Al/Al) and dissimilar materials (Al/Fe, Al/Cu, and Al/Ni). The magnetic pulse welding is a kind of impact welding represented by explosive welding. The impact energy is induced by electromagnetic force generated by interaction among discharge pulse, induced magnetic flux, and eddy ...

Efficient welding conditions in magnetic pulse welding process

Journal of Manufacturing Processes, 2012
This study investigates the experimental research of the appropriated conditions for the magnetic pulse welding of AA6060T6 tubular assembly. Some welding tests were performed with two process parameters: the charging voltage and the width of the air gap between the two parts to be welded.

Modelling of Tubes Magnetic Pulse Welding

Volume 1: Advanced Computational Mechanics; Advanced Simulation-Based Engineering Sciences; Virtual and Augmented Reality; Applied Solid Mechanics and Material Processing; Dynamical Systems and Control, 2012
Magnetic pulse process is used in the forming and welding processes. In order to predict the welding conditions, it is necessary to have an accurate modeling, which involves a coupling between magnetic and mechanical phenomena. In a first step, a numerical modeling of the magnetic field has been developed in the finite elements software ANSYS™, and the

Magnetic pulse welding of tubular parts

AIP Conference Proceedings, 2019
Magnetic Pulse Welding (MPW) enables to join metals with very low heat input, compared to conventional fusion welding technologies. Thus, dissimilar material combinations are producible without the formation of critical intermetallic phases. The process consists of two stages, an electromagnetically driven forming process and the controlled high-speed ...

Magnetic pulse welding in plane geometry

Journal of Applied Mechanics and Technical Physics, 2013
The results of a study of the feasibility of magnetic pulse welding of flat conductors are given. Various inductor circuits and sheet configurations are investigated experimentally. An optimized inductor circuit for accelerating flat conductors by a magnetic field is presented and the necessary diagnostic equipment is developed.

Wave formation mechanism in magnetic pulse welding

International Journal of Impact Engineering, 2010
Abstract Wavy interface morphology is observed in Magnetic Pulse Welding (MPW) similarly to that of the Explosion Welding process (EXW). It is recognized that interfacial waves are formed in a periodic manner and have well defined wavelength and amplitude. The phenomenon of wave formation in EXW has been subjected to extensive investigations in which

Bonding zone formation in magnetic pulse welds

Science and Technology of Welding and Joining, 2002
The microstructural features of the bonding zone in magnetic pulse welds of similar and dissimilar metal pairs have been investigated. The nature of the reactions and phase formation that occur in the magnetic pulse joints displaying a discontinuous pocket type or a continuous transition layer along the bond interface is explained in terms of local ...

Magnetic pulse welding of different metal sheets

Materials Today: Proceedings, 2019
Abstract Magnetic pulse welding (MPW) differs from explosive welding only in the energy source used to drive the flyer sheet: magnetic field energy instead of explosion energy. The interaction of the magnetic field with the sheet involves a number of features related to the amount of the capacitor bank energy used, the heating rate to the melting ...
