Effects of Reactive Interlayers in Magnetic Pulse Welding

, 2018
Surface coatings affect the joint formation in magnetic pulse welding processes (MPW). Two types of coatings were identified in former studies. Anodized layers, for instance, are detrimental for the weld formation if they are not removed before or during welding. Contrastingly, a nickel layer on a steel parent part was found to be advantageous since it
