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 spot welding of bimetals

Journal of Materials Processing Technology, 2014
Abstract One of the main parameters in magnetic pulse welding (MPW) is the requirement of certain distance/spacing called “air gap” between the two sheets or tubes to be welded. This work presents means to alleviate this constraint through stamped humps in one of the sheets.

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.

Magnetic Pulse Spot Welding: An Innovative Approach

Advanced Materials Research, 2014
The magnetic pulse welding is a rapid process (takes place within few micro seconds) that joins both homogeneous and heterogeneous materials in the solid state. The process involves applying variable high current on an inductor to generate Lorentz forces on to the conductive primary part (flyer).

Parameter Identification for Magnetic Pulse Welding Applications

Key Engineering Materials, 2018
Magnetic pulse welding (MPW) is a promising technology to join dissimilar metals and to produce multi-material structures, e.g. to fulfill lightweight requirements. During this impact welding process, proper collision conditions between both joining partners are essential for a sound weld formation.

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

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 ...

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 ...
