Jet Composition in Magnetic Pulse Welding: Al-Al and Al-Mg Couples
Stern Supplement Aug2014112_Layout 1 7/14/15 2:31 PM Page 257 WELDING RESEARCH Jet Composition in Magnetic Pulse Welding: Al-Al and Al-Mg Couples MPW jet phenomena were investigated and jet material composition for similar Al alloys and two samples of dissimilar Al-Mg alloy couples were observed BY A. STERN, O. BECHER, M. NAHMANY, D. ASHKENAZI, AND V. SHRIBMAN the maximum magnetic pressure. The ABSTRACT acceleration of the outer tube through the standoff gap is higher near the open Magnetic pulse welding (MPW) produces a mechanically induced essentially solid end of the tube due to higher magnetic state but partially fusion-type weld, with an extremely small fusion zone and pressure and decreases down to zero at extremely high cooling rates. Composition of material jet emission in MPW was inves- the weld end where there is no move- tigated for similar and dissimilar metal lap joints. The jet residues emitted from Al/Al ment of the outer tube (Refs. 6–8). As a and Al/Mg lap joints were collected and characterized, and their composition was mi- croanalyzed by scanning electron microscopy with energy-dispersive spectometry result, the collision is oblique and the (SEM-EDS). The composition of the jet remains was governed by the degree of rela- initial part of the joint collides at a high tive density difference between the two metal components. The metal jet emitted collision angle and at very high collision during Al/Mg welding was mainly composed of Mg, the metal component with lower velocity; frequently, no bond is formed density.

Magnetic Pulse Welding and Spot Welding with Improved Coil Efficiency—Application for Dissimilar Welding of Automotive Metal Alloys
Journal of Manufacturing and Materials Processing Article Magnetic Pulse Welding and Spot Welding with Improved Coil Efficiency—Application for Dissimilar Welding of Automotive Metal Alloys Chady Khalil, Surendar Marya and Guillaume Racineux * Research Institute in Civil and Mechanical Engineering (GeM, UMR 6183 CNRS), Ecole Centrale de Nantes, 1 rue de la Noë, F-44321 Nantes, France; [email protected] (C.K.); [email protected] (S.M.) * Correspondence: [email protected] Received: 4 June 2020; Accepted: 6 July 2020; Published: 8 July 2020 Abstract: Lightweight structures in the automotive and transportation industry are increasingly researched. Multiple materials with tailored properties are integrated into structures via a large spectrum of joining techniques. Welding is a viable solution in mass scale production in an automotive sector still dominated by steels, although hybrid structures involving other materials like aluminum are becoming increasingly important. The welding of dissimilar metals is difficult if not impossible, due to their differential thermo mechanical properties along with the formation of intermetallic compounds, particularly when fusion welding is envisioned. Solid-state welding, as with magnetic pulse welding, is of particular interest due to its short processing cycles. However, electromagnetic pulse welding is constrained by the selection of processing parameters, particularly the coil design and its life cycle. This paper investigates two inductor designs, a linear (I) and O shape, for the joining of sheet metals involving aluminum and steels. The O shape inductor is found to be more efficient both with magnetic pulse (MPW) and magnetic pulse spot welding (MPSW) and offers a better life cycle.

Probing Magnetic Pulse Welding of Thin-Walled Tubes
Journal of Manufacturing and Materials Processing Article Probing Magnetic Pulse Welding of Thin-Walled Tubes Koen Faes 1,* , Rishabh Shotri 2 and Amitava De 2 1 Belgian Welding Institute, Technologiepark Zwijnaarde 935, B-9052 Ghent, Belgium 2 Indian Institute of Technology, Bombay, Mumbai 400076, India; [email protected] (R.S.); [email protected] (A.D.) * Correspondence: [email protected] Received: 29 October 2020; Accepted: 9 December 2020; Published: 11 December 2020 Abstract: Magnetic pulse welding is a solid-state joining technology, based on the use of electromagnetic forces to deform and to weld workpieces. Since no external heat sources are used during the magnetic pulse welding process, it offers important advantages for the joining of dissimilar material combinations. Although magnetic pulse welding has emerged as a novel technique to join metallic tubes, the dimensional consistency of the joint assembly due to the strong impact of the flyer tube onto the target tube and the resulting plastic deformation is a major concern. Often, an internal support inside the target tube is considered as a solution to improve the stiffness of the joint assembly. A detailed investigation of magnetic pulse welding of Cu-DHP flyer tubes and 11SMnPb30 steel target tubes is performed, with and without an internal support inside the target tubes, and using a range of experimental conditions. The influence of the key process conditions on the evolution of the joint between the tubes with progress in time has been determined using experimental investigations and numerical modelling. As the process is extremely fast, real-time monitoring of the process conditions and evolution of important responses such as impact velocity and angle, and collision velocity, which determine the formation of a metallic bond, is impossible.

Five main methods have been developed to date. These are gas gun welding (GGW), explosive welding (EXW), magnetic pulse welding (MPW), vaporizing foil actuator welding (VFAW), and laser impact welding (LIW). They all share a similar welding mechanism, but they also have different energy sources and different applications. This review mainly focuses on research related to the experimental setups of various welding methods, jet phenomenon, welding interface characteristics, and welding parameters. The introduction states the importance of high-velocity impact welding in the joining of dissimilar materials. The review of experimental setups provides the current situation and limitations of various welding processes. Jet phenomenon, welding interface characteristics, and welding parameters are all related to the welding mechanism. The conclusion and future work are summarized. Keywords: impact welding; impact velocity; impact angle; welding interface 1. Introduction Welding technique has wide applications in the areas of aerospace, automobiles, shipbuilding, pressure vessels, and bridges.

Welding is one of the most widely used metal fabrication methods in world wide. Welding is safe operation when carried out under normal and correct workshop conditions, but it must be pointed out that equipment free from defects and well arranged, properly ventilated , tidy workplace are important factors for safe working. Even though, welding is carried out widely across the world, when certain basic measures and precautions are not followed, it results in injuries, discomfort, loss of eye sight after a longer period, or sometimes even leading to death of the people work there.
